JBL Professional 312CS High-Output 12" In-Ceiling Subwoofer Loudspeaker

Bring authoritative low-frequency impact to your commercial AV, security and monitoring environments with the JBL Professional 312CS high-output 12in in-ceiling subwoofer. Engineered for installers and system integrators, the 312CS adds tight, accurate bass down to 30 Hz to reinforce music, paging and alarm tones without introducing room-rattle or excess heat.

The Kevlar driver and rust- and scratch-resistant finish ensure long-term reliability in 24/7 deployments, while the low-profile white enclosure blends into ceilings for a discreet appearance. Ideal for use with JBL Control full-range speakers, the 312CS upgrades low-end performance for AV, surveillance playback and public-address systems.
