Biamp 910-01583 CMSUB8

Product Overview

The Biamp CMSUB8 is an 8-inch dual-coil in-ceiling subwoofer that adds low-frequency reinforcement to distributed commercial audio systems without a visible cabinet. It is designed for retail, hospitality, and background music installations where a full-range ceiling loudspeaker layout needs added bass at low to medium listening levels. The CMSUB8 uses infinite-baffle loading, so no back box is required for a standard ceiling installation. It is built to partner with small and medium CM-series ceiling loudspeakers for discreet, even room coverage.

Product Description

The Biamp CMSUB8 ceiling subwoofer extends the low end of a distributed audio system so speech and background music sound full across a commercial space. It carries dual 8-ohm voice coils with integrated passive filter circuitry, allowing the subwoofer to blend with satellite ceiling speakers in low-impedance or 70V/100V system designs. Because it is engineered for infinite-baffle mounting, the CMSUB8 drops into a ceiling void without a separate enclosure, which keeps sightlines clean in finished interiors. When it must be built into furniture or a cabinet, Biamp recommends a closed box of at least 20 liters. The aluminum grille resists corrosion, making the CMSUB8 suitable for humid environments such as pool areas, spas, and covered outdoor hospitality spaces. As a commercial in-ceiling subwoofer, it is an efficient way to reinforce bass for background music without dedicating floor space to a bass cabinet. It is a natural companion to Biamp CM-series satellites such as the CM6T and CM20T ceiling loudspeakers.

Key Features

• 8-inch dual-coil driver — The dual voice-coil design lets integrators feed the subwoofer from stereo or dual amplifier channels in a distributed system.
• Infinite-baffle installation — The CMSUB8 mounts directly into a ceiling void with no back box required, simplifying installation in finished interiors.
• Low-impedance and 70V/100V compatible — Integrated passive filtering allows the subwoofer to work in both low-impedance and constant-voltage system designs.
• Corrosion-resistant aluminum grille — The aluminum grille suits high-humidity environments where steel grilles would rust over time.
• Discreet bass reinforcement — The in-ceiling format adds low-frequency energy for background music without occupying floor or wall space.
• Designed for CM-series satellites — The CMSUB8 is voiced to pair with small and medium CM-series ceiling loudspeakers for balanced full-range coverage.
