The JBL LSR4312SP is based on a 12-inch low-frequency transducer with a neodymium motor structure and powered by a 450 Watt amplifier for exceptional low-frequency accuracy and dynamic range. When integrated with LSR4326P and LSR4328P studio monitors, the LSR4312SP Subwoofer extends the low frequency of the system, allowing flat reproduction into the 20 Hz range.

The LSR4312SP's comprehensive 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, 96 kHz digital S/PDIF and AES/EBU inputs can be assigned as LFE or stereo bass management inputs.

The LSR4312SP is the first professional subwoofer to incorporate a powerful analyzer into the speaker along with JBL's next generation Room Mode Correction that measures and automatically compensates for low-frequency problems. Calibration of the system is simply accomplished by connecting the LSR4300 calibration microphone to a networked LSR4328P or LSR4326P, and pressing a button.
