Summary: This unit is perfect for my needs. I have a 10 watt tube amp driving a pair of Bose 301 series 2 speakers. The bass response from the Bose was very poor with my low powered amp but the mids and highs is great. Adding this powered sub woofer has balanced the system perfectly.
Summary: Don't bother with a bigger sub. This is the punchiest, loudest and most accurate sub I've had in over 25 years. And no, it's not "cranked" all the way up, just set to blend into my entire system. Can't say enough about it. It's that good.
Summary: Great subwoofer and it fit the bill perfectly. Great clear sound with substantial bass. Hooked this unit up to my Soundbar with a digital optical cable connected to my cable box what great and better sound. Listening to music and watching movies feels like you are at the movie theater.
