Tannoy CMS 803DC Q 8" Full Range Ceiling Loudspeaker with Dual Concentric Driver (Pair) - TA-CMS803DC-Q

Product Overview

The Tannoy CMS 803DC Q 8-inch dual concentric ceiling loudspeaker, sold as a pair, is engineered for high-ceiling commercial AV installations requiring high intelligibility and even coverage. Its third-generation Ceiling Monitor System (CMS 3.0) technology and proprietary 8-inch Dual Concentric point-source driver deliver consistent broadband directivity for speech and music in tall spaces. Multiple 70V and 100V transformer taps plus 16-ohm direct input make it flexible for distributed audio and high-impedance system design. UL 1480 and UL 2043 certification suit it to plenum air-handling spaces and general signalling systems.

Product Description

The CMS 803DC Q is a full-bandwidth, 360-watt peak, high-sensitivity ceiling loudspeaker built on Tannoy's CMS 3.0 platform. The "Q" variant is specifically designed for high-ceiling applications, incorporating an extended waveguide design with a tight, uniform conical dispersion pattern that maintains intelligibility when mounting heights are significant. Its all-new 8-inch Dual Concentric point-source driver with Omnimagnet technology, mounted on a Torus Ogive Waveguide, delivers more consistent broadband directivity, enhanced intelligibility, and highly accurate, linear response. The UL-certified design suits boardrooms, training spaces, and other rooms where natural speech reproduction is critical.

System integration is straightforward. Multiple transformer taps support 70V and 100V line systems or 16-ohm direct connection, with a low-insertion-loss 60 W line transformer and an accessible front rotary tapping switch. The loudspeaker is optimized for Lab Gruppen low-impedance LUCIA amplifiers, supporting up to eight CMS series loudspeakers per channel for efficient distributed audio designs. A self-aligning five-way clamp mounting system with included C-ring and ceiling tile rails speeds installation, and a removable magnetic grille allows custom painting or optional ARCO designer grilles for minimal architectural impact.

Technical Specifications

Frequently Asked Questions

Does the CMS 803DC Q work on 70V/100V distributed systems?
Yes. It provides multiple transformer taps for 70V and 100V line systems, plus a 16-ohm direct input, selectable via an accessible front rotary switch with a low-insertion-loss 60 W line transformer.

Is it rated for plenum air-handling spaces?
Yes. It is UL 2043 certified for air-handling spaces and UL 1480 certified for general signalling systems.

How does it install into a ceiling?
It uses a self-aligning five-way clamp mounting system with an included C-ring and ceiling tile rails; a cut-out template, paint mask, and tile-bridge kit are supplied, and a plaster (mud) ring is available optionally.

What amplifiers is it optimized for?
It is optimized for Lab Gruppen low-impedance LUCIA amplifiers, supporting up to eight CMS series loudspeakers per channel for efficient distributed-audio designs.

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

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