Soundtube CM82-BGM-II-WH 8" In Ceiling Speaker with white magnetic grill

The SoundTube CM82-BGM-II-WH is an 8-inch in-ceiling background music speaker engineered for commercial distributed audio installations requiring wide, even coverage and reliable 70.7/100-volt system compatibility. Its 8-inch polypropylene woofer paired with a 1-inch silk dome tweeter and patented BroadBeam Ring™ technology produces a 105° dispersion pattern that eliminates dead zones in large retail, hospitality, and corporate spaces. A tuned port on the baffle extends bass response to 45 Hz (±10 dB), adding musicality to background music systems without a subwoofer. The seamless white magnetic micro-flange steel grille is paintable for discreet ceiling integration, and the speaker ships with a tile bridge, UL-listed conduit clamp, and paint shield for straightforward installation.

Available from Creation Networks, the CM82-BGM-II-WH is UL 1480 and UL 2043 listed, making it suitable for use in air-handling spaces (plenum). The six-position rotary tap switch supports 25 V, 70.7 V, and 100 V transformer settings as well as 16 Ω bypass, simplifying system design and inventory. The glass-fiber-reinforced ABS injection-molded enclosure accepts ceilings from 0.9 mm to 40.6 mm thick. With 84.5 dB sensitivity, this speaker minimizes amplifier load across large multi-zone systems.

Technical Specifications

Frequently Asked Questions

Is the CM82-BGM-II-WH compatible with 70.7-volt distributed systems?

Yes. The six-position rotary tap switch supports 25 V, 70.7 V, and 100 V settings, plus a 16 Ω direct bypass for low-impedance applications.

Can the grille be painted to match the ceiling color?

Yes. The white powder-coated steel grille is fully paintable and attaches magnetically, so it can be removed for painting without touching the speaker body.

Is this speaker approved for use in air-handling plenums?

Yes. The CM82-BGM-II-WH carries UL 1480 and UL 2043 listings, confirming suitability for plenum-rated ceiling installations.

What ceiling thickness does it accommodate?

The SpeedWing mounting system accepts ceilings from 0.04 in (0.9 mm) up to 1.6 in (40.6 mm) — covering standard drywall, tile, and plaster surfaces.

How many speakers can one amplifier channel drive?

In a 70.7 V system the number of speakers per channel depends on tap settings and total wattage budget. At the 8 W tap, eight speakers can share a single 64 W amplifier channel.

What accessories are available?

Optional accessories include square grille (GRL-CM-BGM-II-SQ-WH), black grille (GRL-CM-BGM-II-BK), tile bridge (AC-CMEZ6/8-TB), pre-construction bracket (AC-CMEZ6/8-PCB), and junction box (AC-CM-EZ-JBOX).
