Tannoy CMS 603DC PI 6" Full Range Ceiling Loudspeaker with Dual Concentric Driver (Pre-Install,Pair) - TA-CMS603DC-PI

Product Overview

The Tannoy CMS 603DC PI is a pre-install 6-inch dual concentric ceiling loudspeaker for distributed commercial audio in new construction. Sold as a pair, this ceiling speaker uses a point-source Dual Concentric driver and supports multi-tap 70V/100V line operation when fitted with its optional back can. It is well suited to speech reinforcement and background music in conference rooms, retail, and public buildings where the back can is roughed in ahead of ceiling completion.

Product Description

The CMS 603DC PI is a full-bandwidth 320-Watt high-sensitivity loudspeaker built on Tannoy's third-generation Ceiling Monitor System technology (CMS 3.0). Its 6-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. This is the pre-install (PI) version, supplied without a back can so the loudspeaker can be fitted into a separately ordered enclosure during new construction; the line transformer is mounted in the optional CMS 603 PI back can. Multiple transformer taps then support 70V and 100V distributed line systems or 16-ohm direct connection. The unit is UL 1480 certified for general signalling systems and UL 2043 certified for air-handling (plenum) spaces. A self-aligning four-way clamp mounting system with included C-ring and tile rails speeds installation, the removable magnetic grille can be custom painted, and the semi-matt white finish keeps it discreet. This model is part of the wider Tannoy collection at Creation Networks; for a smaller blind-mount option in the same family, compare the CMS 503DC BM. It is optimized for Lab Gruppen LUCIA amplifiers with up to eight CMS-series loudspeakers per channel in low-impedance designs.

Key Features

• 6-inch Dual Concentric driver — A point-source 165 mm Dual Concentric driver with Omnimagnet technology delivers coincident output for consistent coverage and improved intelligibility.
• Pre-install design — Supplied without a back can so the loudspeaker can be installed into a separately ordered CMS 603 PI enclosure during new construction.
• Torus Ogive waveguide — The waveguide improves high-frequency response and directivity for even coverage across the listening area.

Frequently Asked Questions

What does pre-install (PI) mean for this loudspeaker?
The PI version is supplied without a back can so it can be fitted into a separately ordered CMS 603 PI enclosure during new construction; the line transformer is mounted in that back can.

Can it run on a 70V or 100V distributed line system?
Yes, when used with the optional CMS 603 PI back can. The 60 W line transformer offers multiple taps for 70V and 100V systems, plus 16-ohm direct operation.

Is this loudspeaker suitable for plenum ceilings?
Yes. It is UL 2043 certified for air-handling spaces and UL 1480 certified for general signalling systems.

How does it integrate with amplifiers?
It 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.

What warranty and support are included?
The loudspeaker is supported by Creation Networks and backed by Tannoy. Contact our team for the matching back can, quantities, and a project quote.
