Description
The CM82-BGM-II is an 8 inch coaxial two-way in-ceiling speaker engineered to deliver wideband music and paging reproduction. It integrates an 8 inch polypropylene woofer and a 1 inch silk dome tweeter in a drawn steel backcan with a tuned port. The enclosure design provides extended low-frequency output and controlled dispersion for installed audio systems.
Key features include a six-position tap selector for 25 V / 70.7 V / 100 V transformer operation and a transformer bypass position for direct low-impedance use. The driver combination and a tuned port yield a usable frequency response of 45 Hz – 22 kHz (±10 dB) and a measured sensitivity that reduces amplifier requirements. The BroadBeam Ring TM at the tweeter improves mid-range clarity and broadens off-axis performance.
Performance metrics include nominal 16 ohm impedance, 64 W RMS power handling, 128 W max program power, and a maximum SPL of 102.5 dB at 1 meter. Coverage angles average 95 degrees across 2-10 kHz and show defined directivity at higher frequencies. These characteristics support even coverage and predictable voicing in ceiling-mounted arrays.
Connectivity is handled via a four-position ceramic terminal connector and an easy-access rotary tap selector for distributed audio systems. The unit ships with a full-metal tile bridge and a UL-listed conduit clamp for code-compliant installations. A magnetic powder-coated grille is supplied for a low-profile finish and is available in white or optional black.
Typical applications include background music and paging in retail, hospitality, corporate, and education environments where ceiling installation is required. The combination of extended low end and broad dispersion makes the speaker suitable for both music playback and intelligible voice distribution. The transformer options simplify integration into 70.7 V/100 V systems while permitting low-impedance connection for lower channel counts.
Installation is streamlined by the constant-tension fixed-wing mounting system and an included color-coded tile bridge. The drawn steel backcan and ABS baffle provide durable support and fire-rated compliance for plenum installations. Overall, the CM82-BGM-II balances installation practicality with acoustic performance for professional ceiling audio projects.
