Deep, rich bass. Makes the sound jump off the screen. I actually use onlyba fraction of its power cause it shakes the house.

I’m using this subwoofer with a pair of Audio Engine bookshelf speakers and an Onkyo receiver in a medium sized bedroom. The sound is full, well balanced, and capable of more volume than I would ever need. It could easily service an average-sized living room or den. I primarily listen to music including vinyl and this is great for a low-budget hi-fi setup.
One small issue is that that protective felt cover was damaged during shipping and can no longer attach correctly. Fortunately, I didn’t plan on using it.

I am using this subwoofer with the sony series 5 center channel, 2 bookshelf sony series 5 speakers for the fronts, and 2 older polk bookshelf speakers for the rears, along with a older yamaha receiver in a bedroom 5.1 system. This sub sounds surprisingly good, as it has a pleasing tone and integrates well with the rest of the system. I was lucky enough to purchase it from BB at half price ($99), but even at full price its worth the purchase. Highly recommended.

Great subwoofer for the price. If you are looking for a sub $300 sub, then this is a great option. Fills the room (20x26 sq) with bass and decent volume without distortion.

My speakers consist of Bose 930 speakers, Bose cube speakers, and Bose center speaker. I recently bought a new Sony 65" 4K TV and Sony 550 Receiver. Added to these, I bought this Sony subwoofer. I was amazed at how much the sound jumps out and grabs you with the addition of this subwoofer. I've had these Bose speakers for over 20 years and they never sounded as good as they do with this Sony subwoofer. If you don't have a subwoofer for your speakers then you're missing out. This is a great addition at a great price. Bring that movie theater sound to your home.

For years I believed that I had no use for a subwoofer,
until I came across some articles that explained how
it significantly enhanced classical music. So I purchased
this Sony subwoofer when it was on sale, to try it out.
It turned out to be true - and brought out things I had not
heard before in the music! It made the listening
experience more pleasurable, and I am glad I made the
purchase.

I did a good bit of research before purchasing this subwooofer. My intentions were to have a moderately priced one to add on to my home theater. This sub fills that need well. It's small but puts out a good sound and a good bass. Movies and music both have that pop they need. The size and design are both great, nothing too big and looks great as an addition to my current setup. One thing I couldn't find no matter the research I did; this comes with a RCA cable to connect and it's own power cable. If you're looking for a starter sub for a good price, easy setup, and good sound this is it!

I got this to replace another Sony subwoofer that wore out and had severe distortion. That was only 8" and 50 watts. This new one sounds very good and is only slightly bigger than my old one. All the setting controls are in back. They include level and cutoff frequency dials, phase switch, power save switch and power button. There are terminals for speakers but I connected my receiver directly using the line-in jack. Everyone with a home theater system should have a subwoofer. It adds a lot of depth to the overall sound.

Great sound. Easy hook up. Has an automatic off function that is supposed to turn the woofer off if it's not being used, but instead it turns off while in use. Wether there's a song or movie pkaying.

Hi NathanA, Thank you for your time writing this review. We're glad to hear you like the great sound quality and easy connectivity of your SACS9 subwoofer. However, we're sorry if you are having some issues with the unit. Please check the following steps to troubleshoot a subwoofer that turns off by itself:
The subwoofer may have an energy-saving feature that powers the amplifier off if there is not a signal after a specified amount of time. If this is the case, set the Power Save switch to the OFF position to prevent the subwoofer from turning off by itself. Check the cables or speaker wires for proper connection between the subwoofer and the main unit. Ensure it is connected to a working AC outlet. To reduce the possibility of an electrical short, do not connect the subwoofer to an extension cord or power strip. Check the speaker size setting in the Set-Up menu of the main unit. If the speaker size setting is incorrect, the subwoofer may not be receiving any signal For reference: https://www.sony.com/electronics/support/articles/00027291?utm_source=glean
May we contact you to help? If so, please email the below information to [email protected]: Name: Best Buy Username: Telephone Number: Model Number: Issue:
We are sorry for the inconvenience and hope to speak to you to resolve this matter. - Kris

I already had a set of JBL home theater speakers when I bought my latest TV and I needed a subwoofer. After reading reviews for budget-minded subs, I bought this one. Hook up was easy to my Onkyo receiver, everything worked on the first try. The low end is really excellent for either movies or music. A year and a half later, I'm still happy with this subwoofer

I bought 2 of these while they were on sale and used them to replace an old Jensen JP10 subwoofer which finally failed after many years of use. These speakers produce clean clear bass and now having a receiver with 2 sub outs and having 2 hooked into the system gives a fuller bass experience in the room. Nice sound quality especially for the price range.

I bought this sub to pair it with my brand new Sony strdh590 reciever. I already had 5.1 speaker/sub set but unfortunately my subs were not able to utilize the sub jack due to them being powered by the reciever and not a power supply. So I had them bridged with my left and right front speakers, so all audio was about the same with some bass. Not the sound I was looking for. Could not even find The proper wires to assist me in my new venture for sound. So after researching Yamaha xenon and Sony I went with the Sony because it pushed the best wattage of the other competitors in the price range. And I must say this little box rocks. And paired with the Sony strdh590 4k reciever my enjoyment of my purchase had me excited to test everything on it. I have my ps4 pro connected to it with my gaming pc. Unfortunately my games on pS4 would only scale to 1990 resolution with hdr So I ended up plugging the ps4 back directly to me tv which is a Samsung q90t Because it gives me full 3840 resultion I need for cod warzone lol. My pc however is from cyberpower pc and is able to push max 4k at 4096 playing and watching movies on this bad boy is flawless looks like your there. And am able to enjoy all dolby audio and dts sound on in including dtsx and Dolby atmos in 5.1 or 7.1 audio all my devices were all purchased from best buy and now I'm looking into purchasing to more surround sound speakers to utilize 7.1 capabilities. All on all, I am very pleased with my new rig. I definitely recommend the reciever for awesome sound.

First off, know what you are and are not getting for this price point. It is a 10" subwoofer with relatively low wattage, not a 12" subwoofer with high RMS wattage. That said, my 15-year old JBL subwoofer finally quit and I needed a new subwoofer without wanting to upgrade the whole system just yet. I was a little reluctant to get this based on the 10" woofer and low RMS, but decided it might be OK for the short-term. I have to say, I was impressed that it comes with a crossover feature to help fit in to your existing speakers and, frankly, the RMS is adequate for my listening, even in a larger room with 18-foot ceilings. I don't care about seat-rattling bass but do demand solid bass in the mix. In short, this subwoofer delivers bass at a reasonable level and, perhaps more importantly, within the correct sonic range with the included crossover adjustments. At its usual price point, I would recommend without hesitation.

Excellent subwoofer. I use it a large bedroom setting, the sub volume knob is turned 50%...it rocks the desk lol. I've listened to many subs, good ones and bad.
The best part about this sub's bass?
The clarity..The bass is clean and heavy at the same time. That's a perfect sub in my opinion, and I got it for 100 US.
Also? Sony just don't miss.

A good subwoofer. Would like to not have to turn it off and on each time the system is used. Provided wiring for connection to the receiver could have been a bit longer. Otherwise, just a good subwoofer.

I bought this to replace an older sub-woofer of another brand. That older unit had never given satisfactory service.
This new Sony sub-woofer works well. I very much like the fact that it has an automatic setting so it doesn't have to be manually powered on and off. It also has a simply one cord plug in to my receiver.
This unit definitely allows base to come through and enhances movies, especially action movies with lots of loud noises and soundtracks.
