Serious Sub!

All LSR6300 Series Studio Monitors employ Linear Spatial Reference Technology, are magnetically shielded, have mounting provisions, and are THX pm3 approved.

Powered Subwoofer
The LSR6312SP powered subwoofer is based on a 12" woofer with JBL's patented Neodymium Differential Drive NDD and 250 Watts of power. An built-in bass-management system offers all the features you need for today's multi-format surround production including: LCR and Direct LFE inputs, summed output for chaining multiple subwoofers, -4 dB alignment setting, and JBL's new RMC Room Mode Correction rig. RMC Calibration Kit included.

LSR - Linear Spatial Reference Technology
LSR ensures that our speaders sound flat at the mix position. The exact geometry of the wave guide, the interaction of the woofer and tweeter, and the network are designed to provide an accurate listening window of +/- 30 degree horizontal, +/- 15 degree vertical. As a result, the reflected sound which reaches the mix position is smooth and accurate.

RMC - Room Mode Correction
The LSR6328P and LSR3612SP subwoofer are equipped with RMC - JBL's ingenious method of zeroing out bass problems at the mix position caused by room modes. A built-in 1/10th octave parametric EQ lets you correct problems below 100Hz. The RMC Calibration Kit offers up everything you need to identify problematic room modes and tune your system. The LSR25P and LSR6332 enjoy the benefits of RMC when used in a system with the LSR6312SP Subwoofer.
