The LSR4312SP is a 12" powered subwoofer, part of the LSR4300 line from JBL. Ideal for applications in professional music, broadcasting, and post production, the LSR4312SP provides accurate and precise low-end reproduction all the way down to 27Hz. Powered by a 450W amplifier, the subwoofer has plenty of power to kick out anything you throw at it. In addition to offering high-quality JBL audio, the LSR4312SP also includes several advanced technologies including Room Mode Correction, HiQnet networking, and a Linear Spatial Reference design.
Room Mode Correction (RMC) technology analyzes the frequency response of the room and precisely inserts filters to compensate for low frequency inaccuracies. This ensures that signals arrive at mix position with the intended frequency response, eliminating guesswork and creating reliable mixes in any environment. The process also automatically adjusts all speaker levels and sets correct polarity, providing balanced mixes.
