Tannoy CMS 603DC BM 6" Full Range Ceiling Loudspeaker with Dual Concentric Driver (Blind-Mount,Pair) - TA-CMS603DC-BM

Product Overview

The Tannoy CMS 603DC BM is a 6-inch Dual Concentric ceiling loudspeaker built for distributed audio in commercial installations. Sold as a pair, it pairs a point-source coaxial driver with multiple 70V and 100V transformer taps, making it equally suited to 70-volt ceiling speaker systems and 16-ohm low-impedance zones. Its UL 1480 and UL 2043 certifications qualify it for general signalling and air-handling plenum spaces, addressing the code requirements integrators face in commercial meeting and government environments.

Product Description

This blind-mount ceiling speaker uses Tannoy's third-generation Ceiling Monitor System (CMS 3.0) platform and an all-new 6-inch Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive waveguide. The coaxial geometry places the high-frequency dome at the acoustic center of the low-frequency cone, producing wide, consistent broadband directivity and high speech intelligibility across the listening plane. The blind-mount version ships with a fixed, acoustically enhanced zinc-plated steel back can, so it installs as a single integrated unit. A front-panel rotary switch selects 70V/100V transformer taps from 60W down to 7.5W, plus a 16-ohm direct setting for low-impedance amplifier channels. The design is optimised for Lab Gruppen LUCIA amplifiers, supporting up to eight CMS loudspeakers per channel. A self-aligning four-way clamp system, included C-ring, and ceiling tile rails speed deployment, while the removable magnetic grille can be custom painted to match the architecture. It carries a 10-year warranty and is engineered in the U.K. Browse the full Tannoy collection, or compare the ICT-driver variant, the CMS 603ICT BM, for constant-usage rooms.

Key Features

• Dual Concentric point-source driver — The 6.5-inch coaxial driver with Omnimagnet technology aligns high and low frequencies for accurate imaging and even coverage.
• Multi-tap 70V/100V transformer — A low-insertion-loss 60W transformer with front rotary tap selection supports both 70-volt and 100-volt distributed lines.
• 16-ohm low-impedance option — Direct 16-ohm operation lets integrators run the speaker on standard low-impedance amplifier channels.
• UL 2043 plenum certification — Air-handling space certification allows installation above suspended ceilings in return-air plenums.
• Blind-mount back can included — The fixed zinc-plated steel back can ships attached for fast single-unit installation.
• Self-aligning clamp mounting — The four-way clamp system with included C-ring and tile rails simplifies fitting into ceiling tiles.
• Paintable magnetic grille — The removable powder-coated steel grille can be custom painted for minimal architectural impact.
• 10-year warranty — Backed by Tannoy's 10-Year Warranty Program for long-term installation confidence.

Frequently Asked Questions

Is the CMS 603DC BM sold individually or as a pair?
This listing is for a pair of loudspeakers, supplied with the fixed blind-mount back cans.

Can it run on both 70V/100V distributed lines and low-impedance amplifiers?
Yes. The front rotary switch selects 70V and 100V transformer taps, or a 16-ohm direct setting for low-impedance amplifier channels.

Is it rated for installation in air-handling plenum spaces?
Yes. It holds UL 2043 certification for air-handling spaces and UL 1480 for general signalling systems.

What amplifier pairing does Tannoy recommend?
It is optimised for Lab Gruppen LUCIA low-impedance amplifiers, supporting up to eight CMS series loudspeakers per channel.

What warranty and support are included?
The speaker is covered by Tannoy's 10-Year Warranty Program. Contact Creation Networks for system design assistance and project quotes.
