Bowers & Wilkins 15" CTSW15 Custom Theater Subwoofer
Product Description
When you need bass that commands attention, the Bowers & Wilkins CTSW15 stands out with its 15-inch paper/Aramid Fibre bass driver. It's a closed-box subwoofer, meaning you get tight, controlled bass perfect for custom theater setups. Pair it with the external rack-mount amplifier for a complete package.
This subwoofer is designed for those who refuse to compromise on low-end performance. The sealed design ensures you get punchy bass that doesn't bleed into the rest of your audio spectrum, making it ideal for dedicated theater rooms where precision is key.
Integrating the CTSW15 into your existing setup is straightforward, and its robust build ensures it's ready for the long haul. Whether you're in Houston, Dallas, or Austin, MODIA's expert team is ready to assist with professional installation and calibration, ensuring your subwoofer delivers its best from day one.
