Tannoy CMS 503ICT BM 5" Full Range Ceiling Loudspeaker with ICT Driver (Blind-Mount,Pair) - TA-CMS503ICT-BM

Product Overview

The Tannoy CMS 503ICT BM is a blind-mount 5-inch ICT ceiling loudspeaker for distributed commercial audio. Sold as a pair, this ceiling speaker ships with a fixed acoustically enhanced back can for fast single-unit installation and supports multi-tap 70V/100V line operation. Its Inductive Coupling Technology point-source driver delivers consistent broadband directivity with high intelligibility, and is engineered for constant-usage applications such as paging and all-day background music in conference rooms, retail, and public buildings.

Product Description

The CMS 503ICT BM is a wide-bandwidth 200-Watt high-sensitivity loudspeaker built on Tannoy's third-generation Ceiling Monitor System technology (CMS 3.0). Its 5-inch ICT (Inductive Coupling Technology) point-source driver provides an extended frequency range and delivers consistent broadband directivity with enhanced speech intelligibility. ICT drivers are engineered for exceptional long-term reliability, making this model well suited to constant-usage applications. This is the blind-mount (BM) version, supplied with a fixed acoustically enhanced zinc-plated steel back can as an integrated single unit for fast installation in finished or retrofit ceilings. Multiple transformer taps support 70V and 100V distributed line systems or 16-ohm direct connection, so integrators can standardize across mixed zones. The unit is UL 1480 certified for general signalling systems and UL 2043 certified for air-handling (plenum) spaces. A self-aligning three-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 the low-profile ICT variant, compare the CMS 503ICT LP. It is optimized for Lab Gruppen LUCIA amplifiers with up to eight CMS-series loudspeakers per channel in low-impedance designs.

Frequently Asked Questions

What is the ICT driver and why does it matter?
ICT (Inductive Coupling Technology) is a point-source driver design built for extended frequency range and exceptional long-term reliability, suiting constant-usage applications such as paging and all-day background music.

What does blind-mount (BM) mean?
The BM version ships with a fixed acoustically enhanced back can as an integrated single unit, so it installs in finished or retrofit ceilings without a separate enclosure.

Can it run on a 70V or 100V distributed line system?
Yes. The 30 W line transformer offers multiple taps for both 70V and 100V systems, plus 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 general signalling systems.

What warranty and support are included?
The loudspeaker is covered by Tannoy's 10-Year Warranty Program. Contact Creation Networks for specification support and a project quote.
