Tannoy CMS 803DC PI - 360W 8-inch Passive 2-Way 70V/100V Pre-Install Ceiling Loudspeaker with Dual Concentric Driver and 90 x 90-Degree Coverage in White Finish

The Tannoy CMS 803DC PI is a high-performance 360-watt passive ceiling loudspeaker designed for installation applications that demand consistent, powerful audio across a wide frequency range. Featuring Tannoy's next-generation CMS 3.0 technology, this speaker is equipped with a proprietary 8" Dual Concentric point-source driver and Omnimagnet technology, delivering exceptional sound clarity and linear response. The Torus Ogive waveguide ensures improved high-frequency response and broad, consistent directivity, offering enhanced intelligibility across the frequency spectrum. With a frequency response of 47 Hz to 30 kHz (-3 dB) and a maximum SPL of 118 dB peak, the CMS 803DC PI is ideal for demanding environments like retail stores, corporate AV systems, houses of worship, and any large-scale installation where high-quality sound is needed.

Designed as a pre-install version, the CMS 803DC PI features an ultra-shallow back-can design, making it suitable for installations where ceiling cavity space is limited. The speaker includes a self-aligning 5-way clamp system for fast and secure installation, with extra clamp extension to accommodate thicker ceiling panels and a locking design to prevent over-tightening. The low-insertion loss 60W transformer, which can be mounted in the optional CMS 803 PI 16 OHM BACKCAN, provides multiple taps for 70V and 100V line systems or 16-ohm direct input, offering flexibility in a variety of audio system configurations. A convenient front-panel rotary switch makes it easy to select the appropriate tap setting for the system, while the paintable, powder-coated steel mesh grille offers dust protection and can be customized to match the aesthetic requirements of any environment.

The CMS 803DC PI is optimized for use with LAB GRUPPEN LUCIA amplifiers, supporting up to 8 CMS series loudspeakers per channel for scalable and efficient system integration. The speaker's 92 dB sensitivity and nominal impedance of 16 ohms ensure it provides clear, high-output sound without distortion. The semi-matte white finish blends unobtrusively into most environments, while optional accessories, such as the Arco designer grille and plaster (mud) ring, allow for seamless integration into any architectural setting. With its UL-1480 and UL-2043 certifications, the CMS 803DC PI meets stringent safety standards, making it a reliable choice for commercial installations.
