JBL Professional Announces LSR4300 Series Subwoofer

JBL Professional is expanding its LSR4300 family by introducing the LSR4312SP ($1,100) Linear Spatial Reference powered subwoofer for multichannel music, post and broadcast production. The LSR4312SP features JBL’s Room Mode Correction (RMC) technology for measuring and automatically compensating for low-frequency problems. It also employs the Harman HiQnet protocol to network with LSR4300 Series studio monitors and computer-based recording systems. The LSR4312SP will be offered in single and complete 5.1 surround-sound packages with the LSR4326P and LSR4328P studio monitors.

The JBL LSR4312SP is based on a 12-inch low-frequency transducer with a neodymium motor structure and powered by a 450-watt amplifier. The LSR4312SP’s input complement includes a dedicated LFE low frequency effects input and five balanced XLR bass management inputs with selectable cross-over for 5.1 surround sound production. Additionally, stereo 24-bit, 96kHz digital S/PDIF and AES/EBU inputs can be assigned as LFE or stereo bass management inputs.

Calibration of the system is accomplished by connecting the LSR4300 calibration microphone to a networked LSR4328P or LSR4326P and pressing a button.

Using LSR4300 Control Center software, subwoofer bass management and LFE settings and all system settings can be controlled from Windows- and Macintosh-based recording systems. Complete system configurations can be saved in the computer and recalled.
