    I read a lot of reviews before purchasing and for the price this was the best one. Works great as an added power sub to system that already has two passive subs

      Hi Cft28739, Thanks for purchasing your new SA-CS9 115W 10” Active Subwoofer. You’re going to love the room filling sound that Mica-Reinforced drivers can deliver. You’ll experience deeper, more precise bass reproduction than ever before and be amazing as your music and movies come alive! Thank you for choosing Sony and for the 5-star rating! -Carl Sony_US

    Now I purchased this subwoofer during the holidays when they had essentially a half-price deal for $99. So I'm rating it based on that deal. It replaced an old Polk Audio Sub I had for years, definitely doesn't hit as hard or low but its a good speaker. If I get the opportunity to buy another at the lower price I will to upgrade the boom.
