iFinity Wireless Audio Transmitter/Receiver for Subwoofers and Surround Speakers

Just recieved my units yesterday, so keep in mind this review is on initial impressions and about 4 hours of testing. Saying that: This is the first wireless transmitter I have found that sends my LFE channel (subwoofer) across the room without distortion, humm or weird hitches. I was very nervous ordering these honestly because of a few things: 1. The unit does look cheap, no getting around that, I hope the company does a redesign for them as they look like a homemade contraption. Getting rid of the cheap grey plastic for something sleeker would be a start. Additionally, I would suggest to the seller to stop including the RCA cables if you cant put quality ones into the box, they just lower the quality perception of the product. I will say the units are smaller than you think, the picture makes them look rather large, when in fact they are very tiny. 2. The lack of Amazon prime and thus a easy return policy. Things like this are very hit and miss, I've tried 3 different wireless solutions, all ended up getting returned because they would either cut out or introduced noise into the signal (or worse, loss some of the signal, amazing how many of these wireless transmitters cant send information under 60hz). To the seller: Please consider becoming part of Prime or offering a better return policy, I almost avoided this product all together assuming it would be as bad as every other transmitter and I'd have a fight on my hands to return it. The only reason I tried yours was I have already test all the other ones for sale! So with those thoughts out of the way, let's get to the positives: 1. The unit is transmitting the full signal. I did a full range test on the receiver as soon as it arrived, the product description is correct that its transmitting all the way down to 2hz. Very nice given all other units on amazon I tested had a hard drop off at 20hz. the importance of sub 20hz is likely marginal, however, I felt the difference between a straight wired sound vs this unit was barely noticeable, while other units there was something lacking. 2. No drop outs or clicks or boops or any other weird signal distortion sounds. I placed the transmitter in several different areas, behind my receiver, next to a network switch, next to a Xbox One, next to an HTPC and directly behind our Sony X940c. No drops in signal. The receiver sat under the subwoofer which is 14ft away behind our couch. 3. Unlike every other wireless unit I've tried this unit instantly turned on the subwoofer once an LFE signal was sent. Other units would often fail to turn on the sub from its autopower mode, or have a long delay. This one acts like a straight wire connection. 4. The dual channel input and output work great for dual subs. I have run both of my subs connected to it, with my Denon x4200w calibrating each independently. No issues. Calibration distance came in at 23.5ft, so I'm guessing we are seeing a 10-20ms delay in the signal (wired distance came in at 4ft) I will keep this review updated based on how the product holds together over the next year. Needless to say, I recommend the unit over any other wireless units currently for sale on amazon or at Best Buy (Here is looking at you, you horrible Rocketfish transmitter). I hope the seller makes it easier for people to trust the product and brand by offering it with amazons return service.

As many other reviewers have indicated, this device works very well. Its easy to pair the transmitter and receiver, and the sound quality seems very good. I measured it down about one dB at 20KHz, and flat down to 7 Hz (I didn't look lower than that.) The receiver AC output voltage for each channel is an exact match for the transmitter input voltage. I thought the supplied RCA cables were fine -- maybe they've upgraded them after getting so many negative reviews. Based on all this I would give it 5 stars, but . . . The one problem is that the receiver output has a couple of volts DC on top of it, which looks like the result of operating with a single ended output device without a coupling capacitor to block DC. This is fine as long as your amplifier has a blocking capacitor at the input, but otherwise your amp will be dealing with a big DC input voltage and maybe even trying to output that voltage, which would push woofers to their limit, to say the least. For that flaw, only 4 stars! Follow-up 12-19-21 I've gone back and measured the output of this device again, based on some other reviews discussing possible limits to its maximum input and output signal voltages. Here's the thing, the maximum input voltage it can handle is 1.0 v rms. After that the output signal begins to clip. This could be a problem because many setups will use input voltages up to 2 volts or more. The distortion if you exceed the 1 volt input limit would be quite severe. Secondly, other reviews include discussions of the time delay this device puts into the system. I measured it and it is a big 31.3 msec between an input and an output signal. This could be a problem if you're trying to time align your woofer/subwoofer, or at least your AV receiver would have to be able to compensate for this large signal delay. For what its worth, the output signal is also inverted, although that probably hardly matters with a 31 msec delay!

Like many others I have bought cheaper transmitters and receivers to power my sub-woofer and have been deeply disappointed. The three problems have always been the lack of distance the signal would travel if interrupted by walls, the amount of distortion and hum on the speaker and the level of signal interruption when the signal was broken by someone walking in between the transmitter and receiver. These amazingly small devices, with no aerials, far exceed the performance of anything I have previously tried and are now successfully providing a clean, silent signal to my sub-woofer. They are more expensive than many other systems, I bought mine from America and had to buy power plug adaptors which saved £30 vs UK prices, but they actually work which in the end is all that counts. When it comes to syncing these couldn't be easier, you just turn them both on and they sync pretty much immediately, as long as they are in range, if you need to encourage them they have a small sync button. One word of caution, their range through walls, like all the systems I've tried, is pretty limited, not much more than 10m at best, but no doubt this improves dramatically with a line of sight signal.

I bought these to connect a pair of Klipsch R-40PM to a R-100SW subwoofer. The connection was instantaneous and flawless, it was only about 20 feet so not that much of a strain. The only problem is the occasional and sudden boom from the subwoofer, it will catch you off-guard the first few times, that nice bass from the R-100SW. I ordered some subwoofer rated RCA audio cables and the problem went away so I know it is iFinity Wireless that has having problems. Unfortunately I packed them up, and then forgot to send them back in time by 3 days so I am stuck with the trash.

They're....meh. I was hoping for better sound quality from the signal, but it's ok. I'm not getting any feedback sounds like some other customers are saying. No static, no cut outs. The sub and receiver/transmitter is now about 20 ft from the other transmitter behind a couch. I did have to mess with the bass volume and power on the back of the sub itself to compensate for the loss of dynamic range. It was almost like I lost about half of the power the sub has by going to this wireless system. Picture the difference between your sub sound right now, and then having it under two feet of water or in an adjacent room. The signal is constant, it has not cut outs, playing music all day through the surround sound. When I first connected it, the two transmitters would not sync up. As soon as I unplugged/replugged them and hit the sync buttons again, they synced immediately. Am I a little disappointed with the fullness of the bass loss? Yes. Am I pleased I can hide the sub behind the couch and out of sight? Yes. I would like this product one or two stars more if it was half the price it was and/or had better quality sound transfer. (FOOTNOTE) I am NOT using the the RCA cables provided by the company as recommended by another customer reviewer. I have shorter and higher quality cables connecting the transmitter to the sub woofer, and the transmitter to the receiver.

I previously gave it 1 star. The first day I had it, it worked great and allowed me to get my sub back in the living room with the rest of the speakers where we listen to music and watch movies. It really was great while it was working. BUT, alas, ...it died a day later. I called the support number and left a message met with an automated response that all lines were busy and that they would call me back. (Clouds rolling in...) Much to my surprise, they called my back just like they said they would!! ...AND they are sending out a second unit. I will give it another shot because it is pretty slick to have that sub in the living room without wires going everywhere. Sometimes a bad unit sneaks out, that is just a part of life. They offered me a refund too and said they were just interested in doing whatever made me happy, so I opted for a second try, partially as a reward to a company that actually supports their products. Refreshing. This was all taken care of within about 2 hours of me calling in (maybe less). I'll update this if something changes but for now I summarize that 1)Support seems very good, and without accents and bad overseas connections 2)The quality of the sound was great when it was working. Honestly, for me anyways, bass just has to be there in the background. Clarity isn't all that important although I'm sure some audiophiles will disagree. In any case, it sounded as good as it did connected directly to the receiver.

After tons of research and super low expectations, I finally purchased the iFinity Wireless Audio Transmitter/Receiver. Absolutely shocked by how good these are! Frequency is wide-range, and I cannot tell the difference between the wired sub and the identical-brand sub on the iFinity Wireless. Latency might be off a bit, but my Pre/Pro took care of it when I ran Marantz' AV7704 Audyssey MultEQ setup (your mileage may vary). Although the plastic box they are built in might be a negative to some, I have them hidden so it doesn't matter to me. What matters is bandwidth, connectivity, and latency - all of which are excellent. Kudos for a job well done to their engineers! Recommended.

Easy to setup. Does have time delay but easy to overcome by increasing the distance the speakers are away from you. At least double the distance of the mains. I'm using this for my rear speakers so I just set the receiver to 7 channel stereo and adjusted until the music was in sync. Audio quality is good. No interference nor static in my home but others may get some. (Less than 30' away) The level of out was a little bit low, which was okay for me as my amp had a sensitivity/trim control and just turned them up. It seems to be well made even though plastic and should last a good long time.
