Details

Extron CS 26T Plus (part number 60-1505-03) — open-back two-way ceiling speaker cartridge for non-plenum installations.

Where a plenum enclosure isn't required, CS 26T Plus mounts directly with an optional ceiling kit or the CS 120P enclosure, using an infinite-baffle plastic back instead of a sealed can. The 6.5" woofer and 0.75" dome tweeter deliver 112° conical coverage, and a six-position rotary selector switches between 70 V, 100 V, or direct 8 ohm operation, so the same cartridge covers distributed and direct-drive amplifier setups.

Open-back two-way ceiling speaker cartridge for non-plenum spaces
6.5" polypropylene woofer and 0.75" PEI dome tweeter, 112° conical coverage
60 W continuous pink noise / 120 W continuous program power handling
