Value Doesn’t Mean Compromise

Our entry level 203mm (8”) in-ceiling speaker is able to demonstrate the PSB signature hifi sound at a very reasonable price. Featuring a 25mm (1”) treated textile dome and 203mm (8”) polypropylene cone, which produce a wide and immersive sound with a deep bass presence, the CS805 can easily handle large room envelopes. It is a speaker which punches well above its weight, in either home theater or whole home installations.

Available in a 4 pack only.
