CS 120P SpeedMount Enclosure, Pair 70-976-01

The Extron CS 120P is an optional, plenum rated ceiling tile enclosure for the Extron CS 3T full‑range and CS 26T Plus two‑way ceiling speakers. The enclosure installs quickly into 2' x 2' or 600 mm x 600 mm suspended ceilings. It features a shallow 5" (12.7 cm) profile, which simplifies installation into congested ceiling spaces around piping and ducts. The integrated tile bridge rests with the ceiling tile on the grid, evenly distributing the weight of the enclosure and the speaker. This avoids the need to assemble V‑rails and C‑rings, greatly reducing the number of installation steps and the chance of losing installation hardware. Additionally, the CS 120P is reinforced to minimize acoustical vibrations. The CS 120P works with the CS 3T and CS 26T Plus as an innovative two‑piece system that accommodates division-of-labor installations.

In a division-of-labor installation, a low-voltage contractor can begin installing a ceiling speaker during rough-in by placing the CS 120P enclosure into the ceiling grid, and running speaker cable through it. This leaves the AV installer with a simple procedure of connecting the CS 3T or CS 26T Plus speaker to the wiring and securing it into the enclosure. This innovative design greatly simplifies ceiling speaker installation and saves costs, especially when a large quantity is needed for a facility.

The CS 120P features removable sizing tabs, which allow the enclosure to be placed into US‑style 2' x 2' suspended ceilings. The tabs can be removed, allowing the CS 120P to be installed into metric 600 mm x 600 mm ceilings. The CS 120P enclosure is sold in pairs.
