About the PSB CSIW SUB28

Enjoy solid bass without taking up floor space

I love the sound and feel of good bass when I watch movies on my home theater system. The downside? The large subwoofer enclosure that I had to carve out a spot for in my room. PSB's CSIW SUB28 delivers the best of both worlds — tight, clean bass with zero footprint.

Enjoy solid bass without taking up floor space

I love the sound and feel of good bass when I watch movies on my home theater system. The downside? The large subwoofer enclosure that I had to carve out a spot for in my room. PSB's CSIW SUB28 delivers the best of both worlds — tight, clean bass with zero footprint.

This hideaway enclosure houses two 8" woofers that deliver high-quality bass without taking up any floor space. It's an excellent complement to a PSB in-wall or in-ceiling stereo or home theater system.

PSB CSIW SUB28 passive in-wall subwoofer

A built-in back-box keeps dust and dirt out while providing a high-quality sonic enclosure for the two 8" woofers.

Be sure to use matching PSB amplification

The CSIW SUB28 is designed for use with PSB's matching PSB CS 500W subwoofer amplifier (sold separately).

This sleek amp delivers a robust 500 watts of power at 4 ohms — enough to drive this enclosure's twin woofers with authority. 

Installation note: the CS 500W does not get installed inside the wall — it goes in your equipment rack or on a shelf along with your home theater receiver and other A/V gear.

Built-in back-box helps produce high-quality bass

This sub's excellent performance is due in part to its carefully designed sealed enclosure. You get consistently focused, powerful bass no matter what kind of space is behind it in your wall. It also keeps dust and dirt out.

DIY installation
