Q150 Bookshelf Speaker

Replaced Klipsch 600MKII (pair) and Klipsch Reference Premiere RP-504C II Center Channel Speaker with these. to allow for a proper L | C | R channel situation as the RP-504c while a beast, was too big for my room and overpowered the 600MKIIs. While you might think this is a step down (it is, slightly), it served multiple needs. BIG BLACK SPEAKERS AND GIANT CENTER CHANNEL...I needed a very specific stand to accomodate the limited space on either side of the screen (and I wasn't re-hanging that sucker of a 77"). The only thing I could find was a bit cheap looking...dark gray/walnut'ish vinyl veneer, black legs with terrible ventilation and open face storage. It was just big, dark and heavy looking all around and ate up so much visual space. Once IKEA finally restocked thier ventilated doors (game consoles, A/V gear get toasty and I wanted a cleaner look), I jumped on the Besta stand (shown). This required a change of speakers. While the RP-504c (and EXCELLENT center channel) could fit under the screen, the 600MKIIs could not (at least not vertically and their design doesn't lend itself to a horizontal configuration). Enter the KEF Q150 Bookshelf Speakers. If you are looking at these you are also looking at the Q350s as I did. I don't fill a large room (upstairs apartment) and have dual SVS SB-1000 pros (you NEED a sub (s) for these. If sat further away, had a larger room, I would have gone with the Q350s. The Q150s can be placed verticall or horizontally without changing the sound dispersion due to their unique driver design. Note that the Q150s share the same configuration/some of the internals that the MUCH higher priced LS50 Metas do (the Q350s do not as they contain some revisions some audiphiles find wanting). Again, you NEED a subwoofer for these. With three identical speakers (I purchased two pair, so sitting on a spare) across the front sound stage there is no isolation of vocals (at first I did notice some, but I was coming from a mammoth 4 Driver / 1 Horn) what I got was a much wider soundstage. Decent mids and a nicer, more relax high than the mark IIs but cannot be played as high or as lound (which is fine). They are musical and transparent but for sure a step down from the klipsch in the music playback department; the other trade off is these look so much better.

Some information so you know where I'm coming from. I was first exposed to these by my partner who uses them for a 5.1 surround setup. And that is amazing! Being passive speakers they require an external amp. But they can take plenty of power and pump out the volume. Watching Dune with these is an auditory experience! However, this review will focus on my own use case as a pair of near field desktop monitors. I picked these up on sale, to replace a pair of failing mackie cr5s. And let me tell you, it was worth the money. Physically they look amazing. I love the walnut as it gives them a bit more of a classy look compared to the black or white. They are also light but solid. I wouldn't want drop them, but if I did I don't think I would be too worried. The connectors are clearly colored and can use banana plugs or a screw-on connector. (Or you can cheat and just shoved speaker wire into the port). the little cover can be a little tricky to remove. But if you have decent nails it should come out with a little finagling. Being passive you are going to NEED a separate amp to use these. These are known to like power so if you want volume pick an amp accordingly. I am using a Schiit Rekkr through a magni/modi combo. And while it's not the most powerful speaker amp it has been more than enough to run these. On the Magni's 0db gain setting (Middle on the switch) with my computer volume maxed these speakers sit comfortably in the middle of the volume dial and they are crisp and clear no matter what music, game or podcast I've put through them. With the rekkr you can crank the volume and while loud, it's certainly not deafening like you might expect so it's likely a little under powered for the purpose. But it has served me nicely so far. After upgrading I have started to use these more than my HD 6XXs the only things that beats these out for me is my Audeze LCDXs and those cost more than my entire audio setup, so take that as you will. If you're in the market for new speakers and want to take the dive into high quality passive monitors. Grab these on sale and you will not be disappointed. Just make sure the rest of your setup is up to the task to run these power hunger speakers.

Many reading this are probably in the same predicament they find themselves in when the Q150 and Q350 frequently go on sale for $300 and $500 respectively. I too found myself on that see-saw of trying to decide which to buy and if the Q350 was worth the extra $200. I scoured the internet for any comparisons or comments and found very little worthwhile info. From the bits I did gather, there seemed to be a general consensus that the Q150 had cleaner treble, but the Q350 sounded bigger, warmer, had better mids, and more bass. That unless on a budget, one should just spring for the Q350. There’s also speculation that the Q150 is inherently superior because it uses the same size driver and similar size enclosure as the LS50. So, which is it? Let me touch on build and dimensions real quick for those unfamiliar. While I personally find the black iteration of both of these among the most beautiful bookshelf speakers out there, the build leaves something to be desired. While the binding posts might be the cheapest I’ve encountered and the cabinet is pretty hollow, I tend to quickly forgive these factors as long as it sounds good. The matte black vinyl looks great and I’m THRILLED it's not the black ash abomination that finds its way onto so many speakers. The edges are very sharp and clean; a great contrast to the round, centered drivers. There are no grills included, but I would have never used them. Plus, the ones you can buy look cheap and don’t cover the entire face of the speaker. Why KEF didn’t even bother making a grill cutout for the logo of an upcharge grill is beyond me. I’m a huge fan of KEF and their coaxial drivers, and the LS50 still remains my favorite speaker (with subwoofer assistance). I also previously owned the Q150 a few years ago and preferred it in direct comparison to the CCB-8, UB5, and Denton. The Q350 is new for me and I was hoping it would build on what I remembered from the superb Q150. Sadly, it doesn’t. To cut to the chase regarding the value proposition, if the prices were reversed with the Q150 at $500 and Q350 at $300, I’d still purchase the Q150 over the Q350. Unlike the bigger driver and higher price would lead you to believe, the Q350 is not everything the Q150 does but better, nor is it a Q150 with more bass and a bigger sound. It’s a complete side step at best, and in my honest opinion, a flat-out downgrade. I pulled my trusty Studio 570s off mains duty and listened to the Q350 for a few days. While there is always something special to be said about the imaging coaxial drivers provide, these just always sounded way too mellow, too laid-back, and almost muddy. They lack dynamics and never really seem to emerge from their slumber until I seriously crank the volume. At quiet to normal levels, forget it. All the times I was completely uninvolved with the music, I’d instead be constantly urging them to give me MORE. Bring forth the vocals! Bring out the details! Bring up the sparkle! They are indeed very warm, overly so. Almost like KEF experimenting with a Sennheiser or Wharfedale sound. They remind me of the UB5. No glaring faults, but just blah (I still remember liking the UB5 more). The urge to connect a power station and put a trillion watts into them so they can WAKE UP! Vocals definitely suffered because of this. While soft and gentle, they’re simply too muffled. Not so good for quiet, night time, or dialogue-heavy listening. Putting the 570s back in place and BAM, the veil vaporized and the injection of clarity and accompanied shock was like a splash of cold water. I hastily ordered the Q150 after becoming increasingly unhappy with the Q350 and the fact it was no match for the 570s. Hoping I’d at least be able to keep one of the KEFs (almost just for their appearance and coaxial drivers alone), I set the Q150s in the same location, on the same stands, in the same room. 6ft apart with my listening position also 6ft away. To my relief, they were exactly as I remembered them. They had the sparkle the Q350 was completely missing. Vocals, especially female, finally came alive. Everything sounded more realistic and believable. Fine details and imaging seemed more carefully crafted and didn’t get lost in the added midbass and laid-back nature like they did on the Q350. Most surprising was that the bass and extension were comparable, but cleaner and more defined on the Q150. The Q350 has more midbass and smoothness, but of what did it no favors. The soundstage and imaging between the two also sounded pretty indistinguishable and I’d likely fail a blind test. Had I not known of their prices, there is no question I would have thought the Q150 was the more expensive speaker as it has a cleaner, clearer, more balanced sound. But, it's clear to me that the Q150 and Q350 were cut from the same cloth regarding different aspects aside from their sound profiling. For one, the Q150 is also still difficult to drive and definitely sounds better when turned up. Although, they do not suffer from low power or low level listening as much as the Q350 due to their more forward nature and better treble. Both also require a tempered expectation when it comes to bass. If pushed hard, the bass will start to fall apart and become flabby. If you’re a basshead and like party volumes, I shouldn’t be the one mentioning you need floorstanders and/or a subwoofer. Lastly, I found it interesting that while my ear is actually 4-5 inches higher than tweeter level when they’re on my 28” stands, putting 4 inch yoga blocks underneath them to mimic a 32” stand (and become within an inch of ear level) revealed that they didn’t sound quite as good, becoming thinner and brighter. Goes without saying for any speaker, but definitely experiment with speaker height, width apart, toe-in, and distance from surrounding walls. Ultimately, the Q150 was the clear winner here in both value and sound. Many will buy them simply for the fact they’re $200 cheaper… and that’s the real final nail in the Q350s coffin. With that $200 savings, one could purchase a nice pair of speaker stands and still have cash left over. Not to mention, the Q150 is easier to maneuver, place, and experiment with due to their size and weight reduction. They’d work brilliantly on a desk and I anticipate the smaller driver would sound better nearfield. The Q350 is big enough that placement options other than dedicated stands would be limited. Everything said, I highly recommend the Q150 and think it would fit the bill for most people and in most cases over the Q350. But at the end of the day, it's all about the music… right? And that $200 you just saved.

I don't normally write reviews for any product that I purchase unless they really stand out to me, but I felt compelled to write one for the Q150's within minutes of listening to them. I'll admit, I initially bought these because of the looks. The pictures don't do it justice because they look absolutely stunning in person. The perfectly sharp edges and aluminum woofer give it an elegant and modern look. Not to mention, the Uni-Q Driver Array. I'm a big Klipsch fan and while they sound clear and big, the Q150's have perfect imaging. It's almost like the speakers aren't there. Since the tweeter is placed right in the middle of the woofer, it doesn't matter what height or distance you listen to them because the sound comes from a single point source. Build quality: I previously bought a pair of Klipsch RP-500m's, but I had to return them because of the poor quality control nowadays. Out of the box, I could tell that these are expensive speakers. The vinyl wrapping of the cabinet is very sleek and sharp. I couldn't find any imperfections, especially at the edges. I will caution, however, that it can easily get scratched if not being careful. The woofer is assembled perfectly and looks sophisticated with the aluminum material and waveguides. The small KEF "name tag" looks very chic and unique as opposed to other speaker brands simply printing their logo on the cabinet. It's difficult to see in the pictures, but the "Uni-Q Driver Array" is printed in a dark blue color which I thought was black. Nevertheless, great build quality. Sound quality: Wow. It's really hard to describe how these sound because it's almost like the sound isn't coming from the speakers at all. What I can detail is how clear and crisp everything is. The highs are crisp and crystal clear. The mids are clear and warm. Then there's the bass. Do not believe in the frequency range numbers. These definitely go down beyond the claimed 51Hz. I was worried about having to get a subwoofer, coming from RP-500m's, but these produce an astonishing amount of bass for the size. Provided in the box are two bass port plugs with 2 stages: both foam pieces together or you can remove the inner foam piece for just a foam ring. My advice: put them in with just the outer foam because it tightens up the bass and makes it less boomy. All in all, these sound great. I like electronic music mostly and these are perfect for EDM or house music. Deadmau5 sounds amazing on these. Likewise, these will sound great with pretty much any genre of music. I'm powering them with a Nobsound TPA3116 100W mini amplifier and it's plenty of power. I did recently purchase an Audioengine N22 amplifier and while it sounded great with the KEFS, it unfortunately had unbalanced channels. So I'm sticking with the Nobsound for now. I'm sure these would sound much better with a high end amplifier, but it shows how forgiving these are of the power source. In conclusion, these are great for near field listening: punchy bass, warm mids, and crystal clear highs. These definitely need to be broken in because they will sound harsh during the first couple of hours. After that, they become mellow and warm sounding. It's easy to listen to and pretty to look at. Can't wait to see what KEF does in the future!

Having listened to these for a solid 20 hours, I can say confidently that I don't regret choosing these. There are a large variety of bookshelves to choose from now and, having only limited opportunity to hear them, I am comparing these to my more expensive Elac DBR62's. They are being used with a Wiim Amp and an Elac Sub1010. I've heard these described as both warm and on the brighter side. I would say they are on the brighter side. The clarity and soundstage are both very good. Mids and highs come out with such clarity that, with a well mixed track, one could mistake where the sound is actually coming from. There were times it felt as if kit hits were coming from behind me, though the room has much to do with this. For a small office these nail it, in my opinion. I will say, I prefer my DBR62's for sure. They sound much more immense, they fill a room much easier, and the low end and mids hit harder while maintaining a remarkable clarity and airiness at the high end. The soundstage is just as good as these, if not moreso. They are also typically twice the price. Comparing MSRP, the ELACs win hands down in my preference. But at $350, for a smaller budget system, these are just fine and I don't regret keeping them. Pros: - Very detailed - Wide soundstage - Good imaging - Easy to listen to for longer periods Cons: - Veneer is of low quality. Build quality in general should be better for the price. Binding posts are meh. - Needs a sub for lower range depth - Does not come with speaker grills. They can be purchased for an additional $40 ($20 each), effectively raising the price of complete speakers. Overall, these are great and pretty much what I expected. I would say they are 80% of the Elac DBR. Here's a quick tip - If you order the combo with speaker grills, they will likely send you two speakers and only one grill (because they sell each grill separately). Call Amazon and dispute this because the image of the combo shows TWO grills and two speakers. They will send you your second at no cost if this happens. Who would purchase a combo with two speakers and one grill anyways?

I bought these in white for Father's day when they were on sale for $300. I also bought Q Acoustics 3020i's ($300) and Jamo S803's ($200) around the same time to audition them and see which pair I wanted to keep. I ended up keeping the Kef q150s (and the Jamos). All three are very good speakers which I think anyone would be pretty happy to have. All three look really good, which actually matters a lot to me- but I think the Kefs are the prettiest. Build quality is similar across the board, I don't have any issues with any of them. The Jamos are certainly a step down from the other two, but they still look really sharp and nothing was concerning to me. Q Acousitcs may have a slight edge in cabinet construction over the Kefs, but all are pretty good. The Jamo S803's are great- they have a dynamic signature that bumps up the highs and the mid-lows a bit. This is great for apartment-level listening, as I can have the speakers at a moderate level that won't bother my neighbors and still find the speakers fun to listen to. I found the Q-Acoustics very flat- to the point of being comparatively boring at the volume levels I prefer. The Jamo's don't play as deep as I was hoping- subwoofer absolutely needed. The Kef's actually got deeper than the other two by quite a bit, which surprised me because the driver is smaller if you don't count the massive surround. Anyways, the Jamo's give some energy to the higher bass, but fall off too quickly to satisfy me at least. Also, the Jamos are way less efficient than the other two pairs- they need more power. On the other hand, I have an amp rated to 20 watts per channel RMS that was capable of driving the Jamo's beyond a comfortable listening level for me in a mid-sized room. They are inefficient, but you don't need anything special for them to work. The Q Acoustic 3020i's are also very good. I like the rounded corners. They are bigger than they look because these speakers are very deep. I think I like the proportions of the Kefs the best, but again, all three look nice and sound good. The 3020i's have a pretty flat sound signature and are certainly a bit more refined than the Jamos. Imaging and sound stage were similar between the two, however. Again, I kept the Jamos and not the Q Acoustics because I simply enjoyed listening to music using the Jamos more than when using the Q Acoustics. The 3020i's are probably "better" but I personally recommend the Jamos- even if they were the same price, but especially since the Jamos are quite a bit cheaper. I was actually blown away to hear for myself how much better than the other two the Kefs are. In every way. I could truly hear the difference that the Uni Q (concentric) driver makes. The difference was apparent immediately - nothing sounded wrong or bad when I listened to the other speakers, but everything had more depth, space, and clarity coming through the kefs. Plus, to my surprise, these speakers got noticeably deeper than the other two. I still need a subwoofer to suit my own tastes, but these are much closer to the point where you don't need one, and for many genre's these would be perfect on their own. Still, I think the imaging is the real standout feature of these speakers that makes me really love them. The speakers start to blend in to the background and it feels like the room is just making music when you play a well-recorded track with these positioned well. My brother in law has LS50's, and these get impressively near that experience for a fraction of the cost. The LS50s are better in every way, much the same as these Kefs are better than the other two pairs- but the Uni-Q driver is not just hogwash marketing malarkey. At the sale price of around $300 (which these also hit during black Friday and much of the Christmas Season) the decision is easy. But at $550, it isn't clear cut whether the difference is worth the cost. That is going to be a personal decision. I would probably pick the Jamos for the best value. All three pairs of speakers are very good, but the q150's were the clear winner in my comparison. Note: I tested these speakers in a living room, but I am going to put one pair on my desk eventually. However, for now I can't say anything about how the speakers compare near-field.

Okay, so are these speakers incredibly amazing? Absolutely. PLEASE NOTE: these speakers are NOT FOR THE INEXPERIENCED. You have to know what you are doing insofar as your entire sound system design, acoustics, audio source, DAC, amplifier, Etc in order to get something DECENT out of these speakers. You WILL NOT like these IF: - Your audio source is low quality, - you have a noisy DAC, - you have bad room acoustics in your listening space, - you don't use EQ, - you don't have a subwoofer The Fidelity of these speakers is such that if your system has flaws, they will be HEAVILY magnified with these speakers. They are not very forgiving of a suboptimal amplifier, dac, or low quality audio sources. "Tinny". Other people who say that these speakers sound tinny likely have not used a eq, and I doubt they have a subwoofer either, and they probably have a poor quality dac, and horrible room acoustics. So of course they sound tinny ****IF**** you don't have those things in check before getting these speakers. As I said, these aren't for the INEXPERIENCED. You have to know what you're doing to get anything decent from these speakers. They can sound incredibly amazing if you get these things right. In fact, the sound from these speakers is so incredible that I literally forget that there are speakers in front of me when I close my eyes. The sound feels like it comes from every single Direction around your face, it's amazing. HOWEVER, it is amazing because all of the other aspects of a quality audio system are in place. It's going to SUCK if you don't have your system optimized. These things sound so amazing, it's phenomenal. It's otherworldly. Dare I say it is even magical. It's really that good, and honestly, my language here isn't doing it any justice, I suggest that you get your whole system in order FIRST........................., then get these, as you'll have a perfectly adequate Foundation to utilize these to their full potential. You'll hear things that you've never heard before with these speakers when used with a optimized system. If you use these speakers in a suboptimal system, they are going to SUCK, so don't be surprised if they do if you don't have a decent dac, amplifier, and a good audio source. You NEED to use a EQ. Equalizer. Digital EQ via the app that you use to play your music from. You need to TUNE your audio source via digital EQ so that it compensates for the UNIQUE frequency response curve that this speaker has, which is why most people say they sound tinny, when really they don't ****IF**** you equalize them. If you don't use an equalizer, these will sound HORRIBLE. That's right, they sound horrible if you do not use a equalizer, which is the case with MOST high-end speakers. Most high-end speakers do not sound great without equalization. If you don't know what an EQ is, do not buy these. If you don't know what SNR is, do not buy these. If you do not know what s i n a d is, do not buy these. If you do not know what acoustic treatment is, do not buy these. If you do not know what standing waves are, do not buy these. If you do not know what reverberation is, do not buy these. If you don't know what gain is, do not buy these. If you don't know what gain staging is, do not buy these. If you're coming from a cheap set of desktop speakers that are USB powered, do not buy these. If you have never heard of frequency response before, do not buy these. If you do not know what impedance is, do not buy these. If you do not know how much power your amplifier is capable of providing to a given speaker at a specific impedance level, do not buy these. I have heard parts of songs that I have NEVER heard previously on OTHER speakers compared to these. It's incredible. It's almost as if the speakers reveal another half of the song that is otherwise inaudible when played on another set of speakers. Amazing. Phenomenal. Breathtaking. Otherworldly. These things are so f******** awesome!!!!!!!

When I was looking for speakers for my HT set-up a year ago, I read through all the reviews I could find to see what were the best speakers for my budget of $300 or less. ELAC Debut 2.0 B6.2 kept coming up as #1 or #2 in the reviews. The reviews, however, invariably mentioned that if one could extend one's budget more, one should get KEF Q150. That stuck in my head. But KEF Q150s were way over my budget at the time so I ended up with ELACs for front L/R and ELAC Debut 2.0 C5.2 for center, with Fluance AVBP2 bipole speakers rounding up my set-up as side surrounds. They were a bit complicated to set up. I had to tinker with measurements that Yamaha's YPAO was giving me but I got a good sound out of them. At least, that was what I thought at the time. Don't get me wrong, I liked it but something was missing. I especially felt it with the surrounds. Few weeks ago when I was doing further research on surrounds and thinking about upgrading to a better bipole/dipole speaker, I came across some pretty strong opinions on using direct speakers for surrounds which got me thinking that I may have been wrong about choosing bipole design to begin with. At that time I noticed that KEF Q150s were on sale at Amazon for 1/2 the price at $300 a pair. I decided to take a chance and got them to try out as surround speakers. I was amazed with the result. My whole system was instantly transformed. Now I am a believer in using direct speakers for surrounds, although partly it may be the Uni-Q design of KEF Q150, and other direct speakers may or may not be as good for this purpose. But KEFs worked amazingly well. They opened ELACs up, too, so I was very pleased. And they looked so sleek, too! I decided to take a further leap and replace my ELAC L/C/R with KEF Q150s. Let me tell you that results were spectacular. YPAO nailed it right away and for the first time I did not have to change anything except setting speakers to small with the crossover at 80 Hz to redirect bass to the subwoofer. The sound was so good that I could not stop watching Dolby Atmos and DTS:X trailers on youtube. This is an amazing little speaker! Way more detailed than ELAC, well balanced and clean, whether played at high volume or low. At the original price what I did would not have been a viable project for me but with the current discount I got a sound system that I could only dream about before. KEF Q150 at $300 vs ELAC Debut 2.0 at $300? There is no contest! You owe it to yourself to get KEFs. They are in a different class than ELAC. Highly recommended.

très bien de bonnes bases bonne aiguë sont super très content de mon achat

j'ai changé de matériel, il y a 6 mois et je ne regrette pas !!!. Avant j'avais des Amphion 3S(pas du tout le même prix) mais branché sur un ampli home ciné. j'ai tout changé pour ces enceintes et le wiimp amp - le résultat et top. Bon si je mettais les Amphion sur cet ampli je pense qu'il n'y aurait pas photo. Mais pour moins de la moitié du prix et pour une pièce de 25m2 c'est très bien.

Lautsprecher sind seit 45 Jahren ein Thema für mich. Ich habe deren Weiterentwicklung in den letzten Jahrzehnten mitverfolgt, und auch verschiedenste Exemplar selbst gebaut. Wichtig ist mir dabei, unabhängig von der Preisklasse, das ein Lautsprecher eine Bühne für den Zuhörer aufbauen kann, und sich mit verschiedensten Musikrichtungen lange Zeit mühelos anhören lässt. Bislang war sowas in der Einstiegsklasse nicht zu finden, und auch ein Selbstbau würde sich angesichts der mittlerweile stark gestiegen Teilepreise in dieser Preisklasse ziemlich schwer tun. Gesucht habe ich eigentlich nur Lautsprecher für meinen Rechner im Arbeitszimmer, mit denen man auch mal Musik bei gehobener Lautstärke hören kann, ohne dass einem gleich die Ohren abfallen. KEF kenne ich dabei schon aus den Frühtagen meiner ersten Hi-Fi Anlage als seriöse Firma, die sich bemüht ihre Produkte ohrenfreundlich abzustimmen. Aber klappt das auch noch, wenn man nur knapp 320 € für das Paar aufruft? Schauen wir mal. Getestet habe ich die Lautsprecher selbstverständlich nicht in meinem Arbeitszimmer, sondern an einem Pioneer VSX-L305 in meinem Wohnzimmer (28m², akustisch nicht sonderlich problematisch). Die Gehäuse sind recht einfach verarbeitet (irgendwo muss man ja sparen), aber sehen aus 2m Entfernung betrachtet doch ganz gut aus. Eine Frontverkleidung gibt es auch nicht, was mich persönlich überhaupt nicht stört. Die Schraubklemmen sind hochwertig (Bi-Wiring ist nicht möglich, aber m.E. auch verzichtbar), und zweiteilige Schaumstoffpfropfen zum teilweisen oder vollständigen Verschluss der Bassreflexöffnung liegen bei. Die sollte man auch gut verwahren, denn sie dürften bei vielen Nutzern zur Anwendung kommen (dazu gleich mehr). Ich habe sie dann auf meinen Eckhörnern in Ohrhöhe mit jeweils rd. 50 cm Abstand zu den Wänden positioniert, und erst mal mit wenig anspruchsvoller Popmusik begonnen. Ergebnis: auch da wo normaler Weise kaum Bass ist, gab es jetzt jeden Menge davon, sodass selbst die Mitten nahezu erschlagen wurden, und kaum noch Details durchkamen. Ok, sie stehen jetzt ja nicht frei im Raum, sondern in den Ecken, wenn auch mit einem halben Meter Entfernung zu den Wänden. Das kann schon mal zu einer deutlichen Überbetonung der Bässe führen, aber das hier war dann doch des Guten zu viel. Also her mit den Schaumstoffstöpseln, und den Reflextunnel erst mal komplett verschließen. Was für eine Wohltat! Der Bass hat jetzt die richtige Stärke, und die Mitten können sich klar und präzise durchsetzen. Allerdings reicht der Bass nun auch nicht mehr so tief, wenngleich das noch ausreichend wäre. Dennoch, was passiert wohl, wenn man die inneren Kerne aus den Schaumstoffstöpseln herausnimmt? Tja, dann bekommt man, zumindest bei meinem Raum und meiner Aufstellung, das optimale Ergebnis: Der Bass reicht verblüffend tief für ein so einfach konstruiertes Gehäuse und ist auch recht trocken und schnell, die Mitten verraten viele Details (abhängig von der Qualität der Aufnahme natürlich), und die Höhen fügen sich ohrenfreundlich und ebenfalls detailverliebt in das Gesamtbild ein. Da nervt auch nach Stunden nichts. Erster Punkt damit schon mal erfüllt! Wie sieht es jetzt aus mit der Räumlichkeit? Da das Koaxchassis ja als Punktschallquelle agiert sollte die eigentlich sehr gut sein, und das ist sie auch, sofern man genau zwischen den Boxen sitzt. So eine breite, und ziemlich präzise räumliche Darstellung habe ich von einer Fertigbox in dieser Preisklasse bislang noch nie gehört. Hier bekommen auch anspruchsvollere Musikfreunde einiges geboten, was man so in dieser Preisklasse auf keinen Fall erwarten würde. Natürlich sind die dynamischen Fähigkeiten des verhältnismäßig kleinen Chassis beschränkt, aber bevor es da zu Kompressionserscheinungen kommt, hat man schon erheblich mehr als Zimmerlautstärke erreicht. Selbst in meinem Wohnzimmer hinterließen die KEF keinen verlorenen Eindruck. Um Musik bei, der Darbietung angemessener Lautstärke zu hören, reichte es immer. Interessant fand ich auch, dass man kaum Schwankungen im Frequenzgang hört, wenn man sich im Raum bewegt. Natürlich gibt es dann keine räumliche Darstellung mehr, aber ansonsten bleibt der Klang ausgeglichen, ohne das z.B. irgend wann die Höhen einbrechen. Bei der Positionierung beachten sollte man, dass die Bassreflexöffnung auf der Rückseite liegt. Bei einer direkten Montage an der Wand sollte man sie mit den Schaumstoffstöpseln besser komplett verschließen. Die Einbußen im Bass dürften dabei zwar vertretbar sein, ich würde sie aber lieber auf Ständern im Raum platzieren, um kein Potential zu verschenken. Wem das doch recht einfache Oberflächenfinish nicht sonderlich zusagt, der sollte darüber nachdenken, zu Rolle und Glanzlack zu greifen. Bei der Gelegenheit könnte man dann auch gleich die Gehäusekanten (zumindest die der Schallwand) brechen, um so eine noch bessere räumliche Darstellung und einen eventuell leicht lineareren Frequenzgang in den Mitten zu erreichen. Ich denke, dass das einen Versuch wert wäre. Fazit: Dieser Lautsprecher macht vieles richtig, obwohl er nur wenig kostet. Wer bei Musik noch richtig zuhören kann und will, aber nicht allzu viel auf der hohen Kante hat, sollte hier zugreifen. Auch Musikfreunde die nach einem guten Zweitlautsprecher suchen, oder nur ein kleineres Zimmer zur Verfügung haben, sollten sich die Q150 mal anhören. Auch wenn man den Frequenzgang nicht unbedingt als linealglatt bezeichnen kann, diese Lautsprecher machen mehr Spaß als sie kosten. Man kann ihnen lange stressfrei zuhören, und eine so gute räumliche Darstellung findet man in dieser Preisklasse (und auch noch darüber) sonst nicht.

Benutze die Lautsprecher jetzt ca. 3 Wochen. Als Verstärker dient mir eine Röhre mit 2 x 7 Watt. Was soll ich sagen, einfach toll. Musik pur. Obwohl die Lautsprecher nur 86 db Wirkungsgrad haben spielen sie souverän auf. Da passt alles. Man muß ihnen nur eine gewisse Zeit geben zum einspielen (bei mir gut 100 Stunden). Die Verarbeitung ist der Preisklasse entsprechend. Von mir eine klare Empfehlung. Die Lieferung hat auch prima funktioniert.

Me anime a comprarlas después de tener las LS50 meta y emocionarme con su sonido. Las Q150 son más fáciles de mover y su sonido también es muy agradable, equilibrado y detallado. Creo que me volví fan de Kef y su diseño coaxial. Las recomiendo.
