I am very happy with the subwoofer amp. I had to replace my A/V receiver with one that did not have an internal subwoofer amp, and this little amp fit the bill. It works exactly like it did with my previous receiver. If you have passive woofers and your receiver does not have an internal amp for subwoofer output then I highly recommend this little amp. It comes with a crossover switch on the back (B & M). B position is for Subwoofer Mode ( 20 -200hz) M position is for full frequency (20 - 20khz).

Works really good along with my old Kenwood receiver. The addition of a subwoofer makes my old sound systems shine!!!! Now it is 2.1 system! This little amp is compact and enough to drive my 6" passive subwoofer. I just have it cranked halfway and is more than enough to bring those sub-frequencies up to par with the music. Enjoying my music with a new perspective thanks to this little guy. When you get it, don't forget to put the switch in bass mode. Recommended unit!!!!

I installed a surround sound system when I renovated my family room and have 2 of these for my 2x in-wall subwoofers. I also have 2 powering 4 bass “shakers” I installed on my couch. I think they’re great. Plenty of “oomph,” clear sound, don’t run hot, and adjustment knob is super helpful. I definitely recommend.

Tenía un equipo de sonido Onkyo con subwoofer pasivo, hace poco lo reemplacé por uno nuevo que sólo tiene salida para subwoofer activo, mi subwoofer anterior aún servía, así que decidí comprar este adaptador y funcionó a la perfección.

Purchased to replace a blown amp on Pinnacle QAC12 10" subwoofer. Quality and sound are very good. Sound seems better than when using the original amp.

The only thing missing for me was a 1/4inch input jack. Nice and small (the power brick is bigger). Mono amps are not easy to find, using it as an instrument amp.

Bought two of these to drive a pair of 10" DVC subs. These things are BALLER! Absolutely love them. They are surprisingly powerful for their size. I originally set them up with the VC in parallel (so 2Ohms) and the amps were not happy at all. They were astonishingly powerful but their overcurrent cut out is missing a bleed circuit so they would get stuck in a feedback loop. Once I rewired for 8 Ohms they worked perfectly. Low pass filter is set for a quite precise drop off around 45 Hz which is where I like it. Drive my woofers well below 20 Hz (but the speakers are dropping off at that point anyways).

I two of these have this paired with topping E30 dac, L30 headphone/pre-amp and a pair of old Kef 60S on my desk, one per channel obviously. Much stronger bass / mid-range and improved sound stage compared to my old little class d amp (75W). Separation is improved and crosstalk is pretty much eliminated with this set-up. Definitely Hi Value Hi Fi!

Just received after my old power subwoofer amp seemed to put out less bass, thought I'd revive it with a new amp instead of fixing a 20 year old amp. Everything is included (amp, power supply) and all you need to do is use your own speaker wire and hook it up to your subwoofer. In my case I tested the amp with my old car subwoofer and wow...works really good! At first I was a bit disappointed at full max BUT it was because I had the wrong settings, fortunately the instructions provided were helpful. From the factory it comes in setting "M" which is for full range speakers. After I switched the mode to "B", wow, I had to turn down my volume! Pretty legit and nice unit I have here.We'll see on the durability and longevity of this unit as its only been about 2 hrs. Will update as time goes on.
