    Wow. Just WOW. The bass on this thing is crazy good! Super powerful, deep and loud! Even on the lowest settings it packs a punch! Doesn’t ever sound like it’s “too much” or distorted. For the price of this subwoofer, it’s worth the buy!!!

    I love bass and had a sub that wasn't powered with my old LG Receiver. When it went down I paired a new Yamaha receiver and this sub and now the bass shakes the foundation of the house. I can't turn it up anywhere near its maxed volume. Love this sub!

    Convenient connections and easy hook-up to my existing system. Very good Bass Response & easy access to adjustments on rear. This gave my home system its kick back! For the price you can't go wrong. A good size that it can be easily put anywhere in the room.

    This subwoofer only required one line-in wire and the power supply; less wires, which is awesome! Affordable and powerful. This component was a great addition to my home sound system. I recommend this subwoofer!

    After reading the reviews, I decided to give this thing a whirl and I'm happy I did. For the money and the space I have, this sub is perfect. I use it down in my basement and I can hear it the bass up on the third floor at times. Subtle, but you know its there. Highly recommend

    Bought a house with built in speakers but no subwoofer. Didn't want to spend a lot, because may eventually re-do all audio in the house - this fit the bill

    Bought this new sub to go with my component 5.1 setup after my old sub stopped working. Wanted something that would mesh well with my existing setup, connected right away and worked immediately. Turn the dial on the back up and it will rock your entire house! Great sound for movies, games or music. Only complaint would be some of the plastic on it looks cheap, but $250 sub for $150 around black friday I'm happy.

    This sub-woofer ges great with the Sony 1015W 7.2Ch. 4K Ultra HD and 3D PassThrough AV Home Theater Receiver Black STRDH750. Excellent Bass that has yet to distort. I'm very picky when it comes to sound quality, and this sub is great.

    I should have bought two at the sale price. Nice complement to my stereo system in my garage gym. Bringing up the low frequencies makes the music sound much louder and richer without having to crank up the volume overall.
