Tannoy CMS 503DC LP - 240W 5-inch Passive 2-Way 70V/100V Low-Profile Ceiling Loudspeaker with Dual Concentric Driver and 90 x 90-Degree Coverage in White Finish

The Tannoy CMS 503DC LP is a high-performance 240-watt passive ceiling loudspeaker designed for applications where both high-quality audio and minimal mounting depth are required. Utilizing Tannoy's next-generation CMS 3.0 technology, the CMS 503DC LP features a 5" Dual Concentric driver with Omnimagnet technology and a Torus Ogive waveguide, ensuring superior sound clarity, wide broadband directivity, and enhanced intelligibility. The loudspeaker's compact design and powerful audio performance make it an ideal solution for a range of installations, including retail spaces, houses of worship, corporate AV systems, and other environments where space is limited and unobtrusive installation is a priority.

One of the standout features of the CMS 503DC LP is its ultra-shallow back can, specifically designed for applications with restricted cavity space. This feature, combined with a self-aligning 4-way clamp mounting system, ensures that installation is quick, easy, and cost-effective. The speaker includes a removable locking screw terminal connector with loop-through functionality, making wiring and connectivity straightforward. Additionally, the loudspeaker features a paintable powder-coated steel mesh grille that offers dust protection, along with tile support rails and a C-ring for secure installation. The CMS 503DC LP is available with optional accessories, such as an Arco style grille and plaster (mud) ring, for a more seamless architectural integration.

Optimized for use with LAB GRUPPEN LUCIA amplifiers, the CMS 503DC LP supports up to 8 speakers per channel, offering powerful and reliable performance. The low-insertion loss 30W transformer features multiple taps for 70V and 100V line systems, as well as 16-ohm direct input. The CMS 503DC LP offers a frequency response of 88 Hz to 22 kHz (-3 dB), with a maximum SPL of 113 dB peak, ensuring it delivers high-quality sound in both small and large spaces. With a nominal impedance of 16 ohms, this speaker can be easily integrated into various audio systems. The semi-matte white finish ensures that the CMS 503DC LP blends effortlessly into any ceiling, providing both aesthetic appeal and superior sound quality.
