Description
JBL Commercial CSS8018 8" Ceiling Speaker, 10W
The CSS8018 is a compact ceiling-mounted speaker built for installed audio systems where consistent, reliable coverage across multiple zones is essential. Its pre-assembled design and straightforward mounting minimize installation time, letting you focus on dialing in your system levels and coverage tuning across venues, conference spaces, retail environments, and other installations.
Audio Performance & Coverage
This dual-cone 8-inch driver delivers 97 dB sensitivity and a 110° conical coverage angle, spreading sound evenly across typical room dimensions without dead spots. The 50 Hz – 17 kHz frequency range handles intelligible speech and background music cleanly, keeping the low end controlled so your system stays punchy without mud—critical when you're running multiple zones on the same install.
Transformer & Installation
The integrated 10W multi-tap transformer supports 100V, 70V, and 25V distributed audio lines with selectable taps at 10W, 5W, 2.5W, and 1.3W, giving you the flexibility to load-balance your system and keep impedance matching clean across zones. Driver, grille, and transformer arrive pre-assembled and mount with included M4 x 40 mm sheet metal screws to a standard 11.25-inch bolt circle, reducing on-site assembly and getting your system up faster.
