Excellent Value!
I paired this with a Sony SSCS8 center channel speaker. And I have to mention that set up is super easy if you hook-up with a sub-woofer cable. I added the sub-woofer to my 2015 home theater system featuring a Sony XBR-55X850B 55-inch 4K TV, STR-DN1050 7.2 Channel Hi-Res 4K AV receiver and BDP-S6500 Blu-Ray Disc player to enhance the audio richness and to have that “extra punch” when watching movies. Made some minor acoustic tweaks with min-max levels, frequency settings and switched to the power saving mode which is nice when not needed or not in use. Blu-Ray DVDs sound clear and balanced and now the ‘up-scaling’ of the BDP-S6500 to near 4K quality can be heard and felt for an improved viewing experience! And now digital music sounds quite good with HD audio quality from either a CD, Wi-Fi or USB source. The dynamic range combined with the crisp tight bass makes the audio very pleasing for digital and high definition audio. It’s tough to imagine any speakers that can match Sony at this price point. And that’s the beauty of Sony products - affordability that doesn’t compromise on quality or looks.

Great, inexpensive subwoofer
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 specs, great sound!
Great that I can dial in volume and bass cutoff on the unit. We bought a great Sony TV, amplifier, and bookshelf speakers, all with ARC, a while back; just realized that we were missing the sound of a subwoofer. Bought the SA-CS9. Love it.On VEVO, tuned in some Joe Cocker videos recorded in Germany - fabulous sound! Would not have been the same without the woofer.
Hi Lake Minnetonka, We're very pleased to hear you're enjoying your SA-CS9 active subwoofer. 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! Thanks for your purchase! -Sam
