Tannoy CMS 503DC LP 5" Full Range Ceiling Loudspeaker with Dual Concentric Driver (Low Profile,Pair) - TA-CMS503DC-LP

Product Overview

The Tannoy CMS 503DC LP is a 5-inch dual concentric ceiling loudspeaker built for distributed commercial audio in spaces with limited ceiling cavity depth. Sold as a pair, this low-profile ceiling speaker pairs a point-source Dual Concentric driver with multi-tap 70V/100V line operation, making it well suited to background music and speech reinforcement across conference rooms, retail, and hospitality. Its CMS 3.0 platform delivers wide, consistent directivity with high intelligibility for commercial AV installations.

Product Description

The CMS 503DC LP is a full-bandwidth 240-Watt high-sensitivity loudspeaker built on Tannoy's third-generation Ceiling Monitor System technology (CMS 3.0). Its all-new 5-inch Dual Concentric point-source driver uses Omnimagnet technology on a Torus Ogive waveguide to deliver wide, consistent broadband directivity with enhanced speech intelligibility and a linear response. The ultra-shallow depth profile is engineered for retrofit and new-build sites where the plenum or ceiling cavity is restricted. Multiple transformer taps support 70V and 100V distributed line systems or 16-ohm direct connection, so integrators can standardize on a single loudspeaker across mixed audio zones. The unit is UL 1480 certified for signalling systems and UL 2043 certified for air-handling (plenum) spaces, addressing code requirements in commercial buildings. A self-aligning four-way clamp mounting system with included C-ring and tile rails speeds installation, and the removable magnetic grille can be custom painted to match the architecture. The semi-matt white finish keeps the loudspeaker visually unobtrusive in finished interiors. This model is part of the wider Tannoy collection at Creation Networks; for higher output in the same family, compare the CMS 603DC PI. It is optimized for Lab Gruppen LUCIA amplifiers, supporting up to eight CMS-series loudspeakers per channel in low-impedance designs.

Key Features

• 5-inch Dual Concentric driver — A point-source 130 mm Dual Concentric driver with Omnimagnet technology delivers coincident high- and low-frequency output for consistent coverage and improved intelligibility.
• Low-profile depth — The ultra-shallow 98.6 mm enclosure depth allows installation in ceilings and plenums where cavity space is restricted.
• Multi-tap 70V/100V operation — A 30 W line transformer with an accessible front rotary tap switch supports 70V and 100V distributed systems plus 16-ohm direct input.
• 240 W peak power handling — Rated at 60 W continuous and 240 W peak, the loudspeaker provides headroom for both background and foreground program material.
• Plenum and signalling certified — UL 1480 and UL 2043 certification supports use in general signalling systems and air-handling spaces under commercial building codes.
• Tool-light installation — A self-aligning four-way clamp system with included C-ring and ceiling tile rails enables fast single-technician mounting.
• Paintable magnetic grille — The removable magnetic grille can be custom painted, with optional ARCO designer grilles available for minimal architectural impact.
• 10-year warranty — Backed by Tannoy's 10-Year Warranty Program for long-term commercial reliability.

Typical Applications

• Conference room
• Boardroom

Frequently Asked Questions

Is the CMS 503DC LP sold individually or as a pair?
This listing is for a pair of loudspeakers, which simplifies procurement for stereo zones and multi-speaker distributed systems.

Can it run on a 70V or 100V distributed line system?
Yes. The integrated 30 W line transformer offers multiple taps for both 70V and 100V systems, and it can also be wired for 16-ohm low-impedance direct operation.

Is this loudspeaker suitable for plenum ceilings?
Yes. It is UL 2043 certified for air-handling spaces and UL 1480 certified for signalling systems, meeting common commercial building code requirements.

How does it integrate with amplifiers and DSP?
The unit is optimized for Lab Gruppen LUCIA amplifiers with up to eight CMS-series speakers per channel in low-impedance mode, and connects through a removable locking connector with loop-through for daisy-chaining.

Does it fit in shallow ceiling cavities?
Yes. The low-profile design has a front-of-ceiling-to-rear depth of 98.6 mm, making it suitable where cavity space is restricted.

What warranty and support are included?
The loudspeaker is covered by Tannoy's 10-Year Warranty Program. Contact our team at Creation Networks for specification support, quantities, and project quoting.
