In-Wall PSB Subwoofer and 500 Watt Rack-Mount Amp Support Immersive Audio

PSB’s CS IW SUB subwoofer and companion CS 500W amp will both be featured at the upcoming ISE 2019 show in Amsterdam.


After building a reputation for designing value-minded, high-performance in-room loudspeakers, PSB has turned its attention to architectural side of the speaker market. The new PSB CS IW SUB and companion CS 500W amplifier provide integrators a room friendly subwoofer solution.

The PSB CS IW SUB subwoofer and CS 500W amplifier were developed after listening to its dealer base who requested a high-performing in-wall subwoofer. 

“The new PSB CS IW SUB subwoofer and CS 500W amplifier are a direct response to valuable feedback we had from the marketplace,” says Joe de Jesus, custom installation product manager, Lenbrook International, owner and manufacturer of PSB Speakers. 

“Our goal was to deliver a quality LF [low frequency] solution, which is true to the PSB voicing philosophy, but designed with the professional installer in mind. Neither the CI [custom installation] feature set, nor sonic quality have been compromised.”

During the upcoming ISE 2019 show in Amsterdam, it will be previewing its latest subwoofer and rack-mount amplifier in Hall 15 stand number B236 as part of its show activities. 

In addition to showing the latest PSB products, Lenbrook will also highlight products from its Bluesound and NAD Electronics such as the brands' newest wireless whole-house audio products.
