Tannoy CMS 503ICT LP - 200W 5-inch Passive 2-Way 70V/100V Low-Profile Ceiling Loudspeaker with ICT Driver and 90 x 90-Degree Coverage in White Finish

The Tannoy CMS 503ICT LP is a high-performance, full-bandwidth 200-watt ceiling loudspeaker designed for demanding installation applications where both premium sound quality and minimal mounting depth are required. Utilizing Tannoy's advanced third-generation CMS 3.0 technology, this 5" passive 2-way loudspeaker incorporates the proprietary ICT (Inductive Coupling Technology) point-source driver, providing exceptional audio clarity and extended frequency range. This driver, coupled with its 90° conical coverage pattern, ensures wide and consistent sound distribution with enhanced intelligibility, making the CMS 503ICT LP ideal for environments like retail spaces, corporate AV systems, houses of worship, and more. The speaker delivers highly accurate and linear performance, even in demanding constant-usage applications.

Designed with an ultra-shallow back can, the CMS 503ICT LP is the perfect solution for installation spaces where cavity depth is limited. This feature allows it to fit easily into tight ceilings without compromising on performance. The speaker is equipped with a self-aligning 4-way clamp system, which provides a fast, secure, and cost-effective installation. The CMS 503ICT LP also includes a low-insertion loss 30W transformer with convenient front-panel tap switching, allowing for flexible system configuration. Multiple taps for 70V and 100V line systems or 16-ohm direct input options provide excellent versatility for integration into any audio system. For ease of installation, the speaker includes a removable locking screw terminal connector with loop-through functionality.

With its 50W continuous and 200W peak power handling, the CMS 503ICT LP ensures clear and powerful sound reproduction. The speaker is optimized for use with LAB GRUPPEN LUCIA amplifiers, supporting up to eight CMS Series loudspeakers per channel. The CMS 503ICT LP offers a frequency response from 88 Hz to 50 kHz (-3 dB) and delivers an impressive maximum SPL of 112 dB peak, making it ideal for both small and large installations. The speaker is finished in a semi-matte white and comes with a UV-resistant, powder-coated perforated steel mesh grille for durability and dust protection. For a more customized aesthetic, the grille is removable for custom painting, and optional Arco designer grilles and plaster (mud) rings are available to match any decor seamlessly.
