    Adds that extra base for music and adds that extra to movies. Much better than the subwoofer that comes with a sound bar.

    I bought the Sony Core Series speakers from the floorstanding towers to the center channel to the bookshelf speakers to the subwoofer to pair with the Sony STR-DN1080 AVR for a Dolby Atmos 5.1.2 setup and the sound is amazing! I upgraded from a Sony soundbar and what a difference! I am definitely impressed and glad I switched! Get the entire setup on special to make it even more worth it! I would not use the auto-off switch as it tends to turn off during a movie.

    This sub is insane! I can’t believe how much bass this thing produces. Even in a large Open room it is impressive and my dogs are scared of it. It has a standby mode which is nice. when it doesn’t detect any sound it turns itself off and then back on when sound returns, so no need to keep turning the power on and off. There are volume control and frequency control knobs so you can set it the way you want. I could have 2 hooked up to my receiver but I don’t want to blow my house up lol one is plenty

    Great replacement for my Klipsch Subwoofer

    My Klipsch subwoofer's amplifier and paying for a replacement cost me more than replacing it with this Sony subwoofer. The power was the same but in a smaller footprint that is easier to place due to it's smaller size. Also, this sub is able to reproduce lower frequencies than my old Klipsch. Very pleased so far with the sub. The only drawback is the length of the warranty (1 year) vs. the Klipsch (5 yrs.). I'm hoping the Sony quality and price will make up for the deficiency in warranty length. Time will tell.

    Excellent Subwoofer

    My use of this is primarily to fill in the bass in normal listening, which it does excellently. On occasion I have cranked the system up and it rocks the room. Only complaint is that the auto power down does not work correctly - it does not power on again. This is probably due to the fact that I am using the speaker level inputs vs the dedicated input, and the volume is set low. At any rate, that is a trivial problem. For the price this is one really good piece of equipment.

    Sounds fantastic with 3.1 home theatre setup in my 12x12 home study with a 50" Hisense tv, Yamaha receiver and Klipsch speakers with the Sony subwoofer. Music is very detailed and sounds great. Action movies are awesome. Highly recommend this subwoofer. Great value when on sale!

    Another great Sony product. This new sub we bought out performs out older Sony subs by far. I always want the subs where I can manually adjust the bass frequency to hit the highs and lows or in betweens that all songs differ in. Paired with the Sony receiver, we were able to dial in the specific sound and settings we wanted. I have an old dj numark mixer that I use in tandom with the receiver, so it boosts the sound even more.

    Amazing, high-quality sound for a great price. Not boomy or punchy like some subs can be. Added to a pair of powered speakers as my home theater system and it blows away any soundbar I've owned or heard. Highly recommended.

      Hi Monkey,

      Awesome! SA-CS9 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 choosing Sony!

    Very nice. Smooth and clear bass tones. Adjustable range. I thought the neighbor was having a block party until I figured out I was just hearing previously inaudible frequencies. Adjusted the range to keep them from calling the cops on me.
