The new, THX™ approved Series has three models: The LSR6328P is a bi-amplified system with 8-inch woofer and 1-inch tweeter; the three-way LSR6332 has a 12-inch woofer, 5-inch mid and 1-inch tweeter; and the LSR6312SP is a powered sub with onboard bass management.

Designed to counteract the boomy LF standing waves created by a room’s geometry, the LSR6328P and the LSR6312SP feature JBL’s RMC™ (Room Mode Correction) circuits. An RMC Calibration Kit (included with the sub, and optional with the LSR6328P) provides everything needed to measure the room response, identify the dominant room mode and calibrate system response. The kit also includes a test tone disk and simple SPL meter to set the integral 22 bands of 1/10th-octave, analog parametric filters (between 26 and 96 Hz) that notch out offending frequencies. The LSR6328P also provides boundary compensation filters, for use when the speaker is placed/mounted on a wall, corner or large furniture surface.
