    I bought this to add it to my home theater room. I have a good sized home theater room and I was not sure if this would be enough to cover the entire place. This is perfect. Good price and perfect quality. I'm happy

    I had not realized what I was missing with the old smaller subwoofer we had. After installing this Sony to accompany our other bookshelf speakers we noticed how much fuller and stronger the sound was. Good buy for the money.

    I bought the bookshelf speakers and felt they lacked a little in bass so I purchased this subwoofer to compliment them. I have to say the difference is amazing.

    This is a great entry level subwoofer. It definitely fills my man cave with the deep lows I've been looking for. If you just want to get a sub that's not too expensive this definitely will hold you over. I would definitely buy this again.

    This is a very good sounding subwoofer. Gives me the movie theater thump! The only thing i dislike is the “Auto Off Power Saver” kicks in within a few minutes and it makes a clicking noise with it turns off and then on.

      Hi mdelr,

      Awesome! We are thrilled that you are satisfied with the amazing bass sound quality of our SA-CS9 115W 10” Active Subwoofer. We are sorry if its auto power on/off feature didn't live up to your expectations. If there is no signal input for a few minutes, the POWER indicator lights up in red and the subwoofer enters power-saving mode. And while in this mode a signal is input to the subwoofer, the subwoofer automatically turns on. You can actually turn off this function by sliding the POWER SAVE switch on the rear panel of the subwoofer to OFF.

      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 amazed as your music and movies come alive!

      If there's anything we can do to help or you need more information/technical assistance, please feel free to message us at socialsupport@am.sony.com with the following and we'll be more than happy to assist you.

    Underwhelming Sub Woofer

    I returned this product - it was quality built. The only issue was when I played it next to my existing Polk Audio sub - it didn’t have the same punch. Tried it a different levels, different movies/sound tracks, etc. Honestly - I was underwhelmed. I wanted to make sure it wasn’t soMething I was doing wrong so I utilized they “chat” support at Best Buy. Impossible to get them on the phone. Spent 2 hours - was disconnected twice and the answer I finally received was that it had softer lows. Anyway- I am a long time Best Buy customer. This wasn’t a great experience. The Sony subwoofer wasn’t right for me.

    I bought these as part of a package with the rest of the Sony core series line. I’m pretty impressed. To get an entire dedicated 5.2.2 atmos home theatre for around $1,600 is a no brained if trying to decide between something like this and a high end sound bar.

    Can't beat it for the price. That being said, this is a good complement to your system. As a complement to the bass your speakers provide, it is great. Pumping this sub up too high isn't enjoyable. But when this this is over 50% off, it is a great deal. Just isn't the sub for me.
