PSB Speakers Previews CS IW SUB and CS 500W Amplifier

ISE 2019, Amsterdam, NL, 31 January, 2019 – PSB Speakers, long renowned for affordable excellence in loudspeaker design, will preview an all-new, in-wall subwoofer designed to raise the bar on what is considered possible in a low-frequency CI speaker solution. Featuring twin 8” (200 mm) woofers with a low-profile back box, the subwoofer is tuned to complement PSB’s existing in-wall speaker options to create a seamless sound field for audiophile-quality distributed audio projects. The CS 500W is a digital amplifier included with the CSIR SUB In-Room Subwoofer , capable of delivering 500 Watts into a 4 Ohm load and all within a 1U rack space. Expected in-market availability of the subwoofer and amplifier combination is Summer 2019.

“The new PSB CS IW SUB subwoofer and CS 500W amplifier are a direct response to valuable feedback we have had from the marketplace,” explained Joe de Jesus, Custom Installation Product Manager for Lenbrook International, owner and manufacturer of PSB Speakers. “Our goal was to deliver a quality LF solution which is true to the PSB voicing philosophy but designed with the professional installer in mind. Neither the CI feature set nor sonic quality has been compromised.”

The PSB CS IW SUB and CS 500W amplifier will be available for preview at the Integrated Systems Europe show in Amsterdam, The Netherlands, February 5-9, 2019, in Hall 15, stand #B236. Product specialists from PSB Speakers and sister brands NAD Electronics and Bluesound hi-res wireless multi-room players will be on hand to answer any questions.
