### ⭐⭐⭐⭐⭐ Best woofer ever
*by H***A on December 1, 2025*

Best woofer ever used & after 2 years of usage I still like it more & more with every movie watched in my theater

### ⭐⭐⭐⭐⭐ Nice add on
*by A***R on November 26, 2025*

Not overwhelming bass just enhances what is there which is perfect for my setup paired with yamaha amp and old school jbl towers.

### ⭐⭐⭐⭐⭐ Superb for musical instruments like key boards
*by A***A on November 4, 2022*

I just found this item while browsing Amazon looking for better sound for my music setup. Though it gives only the base sound when connected to my Yamaha DGX 670, I connected it through my small amp Yamaha stagepass 400i . Oh my gosh the base sound and and Lower frequency sounds are amazing you can't believe your ears. It's a great addition . Thanks Yamaha and Amazon. I really love it. Unloading , unpacking and connecting is simple even a child can do within 5 minutes. And it fits nicely under the key boards.
