    We bought this Sony Subwoofer at the same time we bought our new Sony 4K 65" TV with Speakers. We were told it was "wireless" with the TV and my husband should have read the reviews as it is not. He had to go back to Best Buy and buy an additional adapter and wiring to make it be Bluetooth compatible. Lesson learned, read about the product prior to purchase!

    I am somewhat a brand person (typically stick with Samsung and/or Definitive Technology) but I must say, for the price, this Sony subwoofer is great! Bought it for my office media centre and it's working perfectly. The auto "sleep" mode is awesome. I just wish they could make subwoofers a little more compact at this level.

    Fairly tight subwoofer, however as reported by others there is an annoying click that is heard when it turns on in Auto mode. No matter what the crossover is set at, if the audio input has no deep bass for awhile it shuts off and Clicks back on upon bass input.

    I'm very happy with this subwoofer. It rounds out my scrapped together 7.1 system. Actually it's so good that I'm going to have to upgrade other speakers to match it. Great sweet spot on price and quality for a medium sized room.

    This subwoofer replaced a Definitive subwoofer from 2006, that died. For the money, I can't complain. I did not want to invest in an over the top quality product. This unit so far, delivers enough to satisfy the tone.

      Hello artooa6,
      That's good news! We're glad that our Sony Core Series 10" 115W Active Subwoofer met your expectations and it is worth the price. The Sony SACS9 gives you deep, rich bass from this powerful active subwoofer, and it includes a built-in amplifier with up to 115 W power output. The unit is powerful and compact, perfect for easy installation in tight spots. Because of the reduced baffle area, the speaker minimizes sound field distortion for optimum clarity and precision. Thank you for your purchase and for choosing Sony! - Marco Sony_US

    This is a solid subwoofer with a great sound. I'm using a Pioneer receiver and my other 5 speakers are Infiinity and they all work well together. My only complaint is I like to turn of the subwoofer when I watch something in the middle of the night and there is no power switch. So I have to unplug it.

      Hi JohnM,

      Thanks for commenting! We are so happy to hear you are enjoying the amazing bass sound quality of our SA-CS9 115W 10” Active Subwoofer. We appreciate your feedback with the power switch. The SA-CS9 actually has a power button on the rear panel that you can press to turn on/off the unit. It also features an auto power on/off function. 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. This feature can also be turned off 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!

      Thank you so much for purchasing our SA-CS9 and for choosing Sony!

    This is a good sub-woofer and I'm happy with what I paid for it. I previously had a Monoprice Sub and the internal amp failed. So far this is working great.
