JBL Cinema 3635 LC-SUB 18" Pro System Subwoofer
The JBL 3635 LC-SUB is a cinema-grade subwoofer engineered for control-room and mastering-suite installations where deep, articulate bass reinforcement demands precision monitoring. Its shallow profile cabinet fits discreetly into compact studio spaces while delivering the low-frequency performance required for critical listening and accurate mix translation. This unit combines JBL's professional engineering with practical studio-environment constraints.
Design & Build Quality
Built with a compact footprint of 46 x 25.625 x 14.5 inches, the shallow cabinet design minimizes the floor or wall space required in tight control rooms while maintaining structural integrity at 113 lb. The barrier strip screw terminals provide secure, professional-grade connections suitable for permanent studio installations and integration with mixing consoles and monitor controllers.
Audio Performance
The 460 mm (18-inch) low frequency driver delivers a frequency range of 38–100 Hz (±3 dB) with extended response down to 28 Hz at -10 dB, ensuring tight, articulate bass that sits cleanly under your mix without low-end bloat or phase issues. Maximum SPL of 125 dB at 1 meter and 300W AES power handling enable this subwoofer to integrate seamlessly into monitor stacks and surround-sound mixing setups requiring controlled low-end reinforcement and flat in-room response.
