Extron CS 120P (part number 70-976-01) — plenum-rated SpeedMount enclosure pair that mounts a CS 3T or CS 26T Plus speaker cartridge in a suspended ceiling.

The CS 120P is the enclosure half of Extron's SpeedMount ceiling speaker system — an integrated-bridge tapered cube that rests directly on a 2 ft x 2 ft or 600 mm x 600 mm grid, so there's no separate tile bridge to assemble. Its 4.9" depth is built for tight plenum spaces around ducts and pipes, and because the enclosure and speaker cartridge are ordered as separate parts, low-voltage and AV crews can install the enclosure and cartridge on different schedules.

Key Capabilities

• Plenum-rated SpeedMount enclosure pair for CS 3T and CS 26T Plus speaker cartridges
• Integrated bridge eliminates separate tile-bridge assembly on 2 ft x 2 ft and 600 mm grids
• Only 4.9" deep for congested plenum spaces around ducts and pipes
• UL 2043 listed for plenum airspace use, UL 1480 listed for pro audio systems
• Built from aluminized fiberglass, plastic, MDF, and steel with glass polyfill insulation
• Supports division-of-labor installs, letting enclosure and cartridge ship and install separately

Where It Is Used

Used in conference rooms, classrooms, lecture halls, and auditoriums where a SpeedMount CS speaker cartridge needs a plenum-rated ceiling enclosure without a separate tile bridge kit.
