Make your Bass Pop 

Looking to augment your stereo system? Want some deep bass to complement your bookshelf or floorstanding speakers? It may be time to consider a dedicated subwoofer. Take a look at our Sony SA-CS9 10 inch Active Subwoofer. Part of their Core Series line of speakers, this is the best pure subwoofer in Sony’s lineup. It’ll make you feel like you’re right in the action! 

Sony = the Deepest Sound 

The part of the speaker that makes sound is called a driver. Every speaker -- the speakers in your headphones, your earbuds, and your favorite devices -- has these. Dedicated subwoofers, like the SA-CS9, use single large bass driver with a dedicated, onboard amp to produce the deepest, richest, most intense and visceral sound any speaker can make. 

One Unique Woofer 

Perhaps the SA-CS9’s most impressive feature is in its 10” woofer. Driven by a unique dual-layer mica foam diaphragm, their upper surfaces deliver rich, subtle, and faithful sound quality, while the bottom layer delivers an incredible depth of response with its low weight and great strength that only a Sony subwoofer can achieve.  

Sony’s Biggest Bass 

You'll be mesmerized by the incredibly fast and powerful bass response! With a dedicated rear-firing port and fine timing alignment across the entire frequency range, the SA-CS9 realizes deep, rich, natural bass. Rock your senses and give your music the foundation it deserves, the way the artist intended. 

115 Watts of Amplified Goodness 

Feel your bass rumble more powerfully than ever with the SA-CS9’s dedicated, onboard 115-watt amp. Balance out the rest of your sound system’s highs with deep, intense lows. This Sony 10 inch sub will make you feel like you’re in the mosh pit or the middle of the action even in your own home theater! 

Created for Audiophiles 

With its incredibly precise reproduction, positioning, and depth, the SA-CS9 delivers a rich, full soundstage. Fill your room with wall after wall of amazingly detailed sound and feel the energy and passion of the original performance! 

Superior Sony Construction 

Featuring careful component selection, meticulous construction, and outstanding attention to detail, our SA-CS9 is built to a better standard than any other subwoofer in its price range. Experience the difference a truly high-end system makes, even on a medium-sized budget.  

Build the Complete Set 

Ready to expand your stereo system? The SA-CS9 is just one part of Sony’s CS sound system. Between the SS-CS3 floorstanding speakers, SS-CS5 bookshelf speakers, and SS-CS8 center channel, we’re sure to have every speaker you need to flood your home theater with bright, clear Sony sound.
