Find a Dealer

Value 2-Way In-Ceiling Loudspeaker

Sharing the same tonal characteristics as its family members, this model is a wonderful introduction to PSB sound at a very affordable price. Featuring a 19mm (¾”) soft dome fabric tweeter and a 165mm (6½”) polypropylene cone, it’s well matched to offer wide and constant dispersion throughout its frequency range. Perfect for whole home audio, or home theater installations.


This superb group of architectural speakers embody over 40 years of cutting-edge research in the field of acoustics and loudspeaker design. Musical, refined, and nearly invisible, these speakers can create a beautiful ambience, even in larger spaces. Because their sonic signature is identical to other PSB speakers, the CS series can integrate perfectly as part of home theatres or as the soundtrack of the connected home. Since PSB has in-room, on-wall, outdoor, in-wall and in-ceiling designs at many different price points, it makes it easy to specify an audio system that you know will turn out right, be easy to specify and install, and will absolutely thrill even your most discriminating clients.

There are seven models in this series, and all feature frameless magnetic grilles with invisible scrims. Both round and square grilles are provided (CS605, CS805 only have round grills), simplifying and reducing your inventory requirements. Each model features an improved, simple, foolproof mounting system using heavy duty doglegs. Cutting templates are included. Pre-construction brackets and back-cans are also available.
