Customer Ratings & Reviews

Bought this as an add on to my Sony Str-dh820. Was immediately happy with it's performance. Has great bass and rattles my walls and windows. I've seen a ton of reviews where people say they need a second one. I wouldn't say I need a second one, but definitely want another. But just one provides excellent bass overall.

I’ve been looking for one that matches with my bose home theater speakers— and it worked just great. Easy to connect, great to listen to

This Subwoofer provides just the right amount of bass for my basement entertainment area. The basement is a large open room and the subwoofer is near the back of the room. The bass travels throughout the room and provides great sounds for movies and music. I am very impressed with the performance of this subwoofer.

The STR-DH790 can run both at the same time. They are suited to a high quality system tuned with DSP. You wont be disappointed, these are the real deal.

I bought two of these. I have been using one in my living room to supplement my in-ceiling speakers and it has definitely improved the range and quality of sound. I mostly use the sub and in-ceiling speakers for background music when entertaining or when cleaning the house or doing dishes and it does the trick. The sound is much better with the subs providing the bass range. I would recommend for the price. It would be a five star if the sound was even better, but I don't think I can do much better for the price.

Very good bass! hooked up to a Sony STR-DH790 with no problems using the RCA cable that was included. Replaced an old Sony SA-WMSP68 active subwoofer that i had for many years that had stopped working. very pleased and will probably be buying a 2nd one of theses in the future since the STR-DH790 has 2 sub outs.

The sound quality is very good. The deep bass is really shaking.

sound quality %100 sony always do real quality products base is amazing

Provides excellent bass response to the whole room. Highly recommend purchasing with the Sony STR-DH590 Multi Channel AV Receiver for home theater use. Easy set up with one RCA cable (provided) to port on receiver. Nice features include volume output control for bass level, cutoff frequency knob to eliminate certain sound ranges, and auto-off power control to save power when receiver powered down.

Sony makes excellent audio gear and this is no exception. The bass is shockingly big and more than overkill for most apartments. There are several settings on the back to control the intensity. Fantastic speakers from my favorite company for home electronics.

The Sony SA-CS9 subwoofer is a basic ,but excellent choice for complimenting a 5.1 system in a small to medium size room like mine. Besides it being on sale for the holidays, the reviews that I read online for this particular subwoofer were well received by all the professional reviewers. This, plus that it was a Sony product, influenced me to seriously consider it on my short list of subwoofers to chose from. It did take a bit of trial and error to find about a perfect location to get the optimal performance from it, but it was well worth the effort. This sub works well with movies soundtracks that feature a lot of low frequency effects, and greatly enhances the overall experience that one gets from action, science fiction, and superheroes movies. Overall, the Sony SA-CS9 subwoofer gave me everything that I was looking for to compliment my small satellite speaker system. Therefore, I give this subwoofer two thumbs up for anyone who wants to greatly benefit their moderately priced 5.1 A/V system.

I purchased this to compliment the built in speakers in the Sony A1E OLED TV. You connect it to the analog out and select subwoofer. Then use the Low Pass Filter control to select the amount of low end to come through the subwoofer and the gain to adjust the volume. You can mostly do this by ear, play with the controls a little and see what sounds right to you.

Affordable sub delivers clear low end sound. Will not shake the walls or rumble floors but is clear and solid.

Works great. Music sounds great. Totally enhances the bass.

So this would be perfect to add to a small home theater or if you are in some type of place where you can't be that loud. Unfortunately in my system it is kind of quiet because it only does like 100 watts. My main loudspeakers do 160 watts per channel so 320 total at 8 ohms. This unit was just too quiet to do anything substantial for the bass because I couldn't even get it volume matched at max volume on this unit's volume control. My preamplifier has double RCA outputs and even at mid-level volume on my pre-amp it's just not loud enough. Would suggest you get something with at least 200-400 watts if you already have a regular HiFi system or movie watching system. But, if you're in a small room or want something quiet for a place where you have neighbors above or below you or to the side this may be the unit for you. Also running it on normal polarity helped immensely with the linearity of the response.

I went to this from an infinity syb that started popping. The bass is great but I wish it aimed towards rhe floor like my infinity sub did. I recommend hiding it behind something instead of having it face you to have a more realistic boom feel.

does just is needed. Sounds great, Easy to connect and adjustable sounds

This is an great sub-woofer, sound great, looks great & easy to setup

This subwoofer is the best purchase I’ve made after since buying my MacBook. The base is very deep and you can feel it if you have the right system. Just make sure that you put it in a corner where it’s closer to the outside wall of the house because it will reverberate through the walls

great sound excellent for the price a great value for anyone
