In-ceiling loudspeaker subwoofer

8-inch ceiling mount loudspeaker subwoofer. Loudspeaker designed for voice and background music.


The CS-8SUB is an in-ceiling loudspeaker subwoofer with a great sound performance. It features a 8” woofer with 80W AES in a low impedance and it’s a loudspeaker designed for extended the low frequency of the CS ceiling speakers.

It uses a 100V / 70V Line transformer that offers a selection of 50/25W ( 1.9W @ 70V) delivered to the louspeaker system using high impedance lines or 8Ω bypass.

The baffle, bezel and rear enclosure are constructed from ABS. The rear enclosure adds damping material, providing an optimum internal volume for extended low-frequency performance.


Perfectly suited for:

→  Corporate training rooms, ballrooms
→  Convention centers, exhibit halls
→  Houses of worship
→  Malls, airports, nightclubs, bars, restaurants
→  Auditoriums, museums
