Tannoy CMS 801 SUBPI 8" In-CeilingSubwoofer

Tannoy CMS 801 SUB PI — a discreet 8-inch in-ceiling subwoofer delivering deep, controlled bass for commercial installations.

The CMS 801 SUB PI is engineered for permanent in-ceiling installation in commercial spaces such as retail environments, restaurants, conference rooms, and houses of worship. Its passive inverter (PI) design exploits the cavity above the ceiling as an acoustic chamber, generating powerful low-frequency output without a dedicated enclosure. The paintable grille and bezel integrate flush into virtually any ceiling finish, maintaining architectural aesthetics while reinforcing the low-frequency foundation of a distributed audio system.

8-inch low-frequency driver optimised for in-ceiling passive inverter loading

Bandpass-style low-pass filtering for tight, well-defined bass reproduction

Paintable grille and bezel for seamless architectural integration
