Tannoy CMS 603ICT PI 6" Full Range Ceiling Loudspeaker with ICT Driver (Pre-Install,Pair) - TA-CMS603ICT-PI

Product Overview

The Tannoy CMS 603ICT PI 6-inch ICT ceiling loudspeaker (sold as a pre-install pair) is a wide-bandwidth, 240-watt high-sensitivity speaker built on Tannoy's third-generation Ceiling Monitor System (CMS 3.0) platform. Its proprietary 6" ICT (Inductive Coupling Technology) point-source driver delivers consistent broadband directivity with enhanced intelligibility for speech and music. UL 2043 plenum certification and a pre-install design make it ideal for boardrooms, conference rooms, and air-handling ceiling spaces.

Product Description

The CMS 603ICT PI uses an all-new 6" ICT point-source driver with extended frequency range, delivering 91 dB sensitivity and broad, even coverage. The Inductive Coupling Technology crossover is set at 7 kHz, providing exceptional long-term reliability that suits constant-usage applications in demanding commercial environments. This pre-install version ships without a back can, allowing first-fix mounting during construction; the optional CMS 603 PI back can adds 70V/100V transformer taps or 16-ohm direct operation when fitted.

Engineered for high-durability use, the speaker is UL 1480 certified for general signalling systems and UL 2043 certified for air-handling (plenum) spaces. A self-aligning 4-way clamp mounting system, C-ring, and ceiling-tile rails are included to speed installation, and a removable magnetic grille can be custom painted or upgraded to an optional ARCO designer grille for minimal architectural impact. It is optimised for Lab Gruppen LUCIA amplifiers, supporting up to 8 CMS-series loudspeakers per channel.

Frequently Asked Questions

Why is this a pre-install (PI) version?
The pre-install version ships without a back can, allowing the speaker frame to be mounted during first-fix construction before the finished ceiling and electronics are added.

How do I get 70V/100V operation?
Fit the optional CMS 603 PI back can, which houses the transformer and provides 70V/100V taps or 16-ohm direct low-impedance operation.

Is it safe to install in a plenum ceiling?
Yes. The speaker is UL 2043 certified for air-handling spaces and UL 1480 certified for general signalling systems.

Can the grille be painted to match the ceiling?
The removable magnetic grille can be custom painted, and optional ARCO designer grilles are available for minimal architectural impact.

How many can run on one amplifier channel?
It is optimised for Lab Gruppen LUCIA amplifiers, supporting up to 8 CMS-series loudspeakers per channel. Contact our team for system design support.
