JBL Cinema 3635 LC-SUB 18" Pro System Subwoofer
The JBL 3635 LC-SUB is a cinema-grade subwoofer engineered for studio and control-room environments where precise, controlled bass reinforcement anchors the low end of critical monitoring chains. Its shallow profile cabinet integrates discreetly into space-constrained studio setups while delivering the sub-bass performance required for accurate mixing and mastering. This unit combines JBL's professional engineering with practical studio installation constraints.
Design & Build Quality
Built with a compact footprint of 46 x 25.625 x 14.5 inches, the shallow cabinet design minimizes the studio footprint while maintaining structural integrity at 113 lb. The barrier strip screw terminals provide secure, professional-grade connections suitable for permanent studio installations and multi-unit bass-management systems.

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 reproduction without muddiness or phase issues in the mix. Maximum SPL of 125 dB at 1 meter and 300W AES power handling allow this subwoofer to integrate seamlessly into studio bass-management systems, revealing low-frequency detail essential for mixing pop, hip-hop, electronic, and bass-heavy genres.
