Impressive
I had just returned a more premium branded sub that cost 3 times as much. This blows that out of the water! Definitely worth it. I was highly surprised. Has plenty of power and sound is deep and rumbling like thunder.

Excelente produto
Estou usando esse subwoofer em uma sala de 40m2. Ele tem a presença do subgrave muito nítida e forte. Mesmo em volumes baixos. Toca muito bem, subwoofer de impacto, muito top mesmo.
