Bowers & Wilkins Custom Theatre Subwoofer

Yes, as a passive subwoofer, the CTSW10 does not have a built-in amplifier. You will need to pair it with a separate power amplifier, such as the Bowers & Wilkins SA1000, to drive the unit effectively.

The CTSW10 is designed specifically for custom installations, including in-wall mounting. However, because it is a substantial piece of equipment, you should ensure your wall structure is reinforced to handle the weight and vibration of the driver.

The sealed enclosure design provides a tighter, more controlled, and accurate bass response. It is generally easier to integrate into cabinetry or walls because it doesn't require the airflow clearance that ported designs often need.

As the smallest model in the Custom Theater range, the CTSW10 is best suited for small-to-medium-sized rooms. For very large spaces, you may want to consider using multiple units or upgrading to the larger 12-inch or 15-inch models in the same series.

Because the CTSW10 is a sealed, passive unit, it is virtually maintenance-free once installed. Just ensure the mounting surface is secure and vibration-free to maintain optimal sound quality over time.
