From Our Research Team:Powerful Subwoofer with Room Mode CorrectionJBL caused quite a stir with their introduction of the LSR4326P and LSR4328P monitors, and now they have completed the set with the introduction of the LSR4312SP subwoofer. A system configured with the LSR4312SP subwoofer provides professional bass management of the main channels, plus LFE (low frequency effects) input, adjustable crossover points, and powerful features for surround sound production.JBL LSR4312SP Powered Subwoofer at a Glance:
12" low-frequency driver with 450-watt power amplifier Based on a custom 12" low frequency transducer with a Neodymium motor structure, the LSR4312SP is powered by 450 watts of amplification providing exceptional dynamic range and low frequency response into the 20Hz range. The new sub includes balanced analog and digital inputs to enable multi-channel production with comprehensive bass management capabilities. The perfect sub for LSR4300 Series monitors The JBL LSR4312SP sub is the ideal foundation for a 2.1 or 5.1 surround monitoring system when teamed with LSR4326P or LSR4328P monitors. The LSR4312SP can be networked with the LSR4328P or LSR4326P to create integrated surround sound systems without the need an external monitor controller. Room Mode Correction compensates for problem standing waves Great mixes start with accurate monitors. The LSR4312SP incorporates JBL's next generation RMC Room Mode Correction system incorporates a powerful analyzer into each speaker that automatically analyzes and compensates for problems caused by low-frequency standing waves and proximity to boundaries. Truly putting technology to work, all of this is accomplished by simply plugging the LSR4300 calibration microphone into the speaker and pushing a button. A JBL first, the LSR4300 meter provides a reference of the output from each speaker in the system. The results are a revolution in professional mixing: a calibrated listening environment where the monitors truly work in harmony with the room. This creates a stunningly clear and articulate sound stage enabling reliable mixes that translate faithfully to the outside world. Part of an intelligent monitoring system Control of system level, individual speaker solo, input source selection, high- and low-frequency EQ settings, and adjustment of all parameters can be made from each speaker's front panel, with the system’s infrared remote control, or with LSR4300 Control Center Software. For unprecedented performance and convenience the LSR4300 Series incorporates the new Harman HiQnet protocol that enables a coordinated calibration of all speakers, intelligent configuration of surround sound systems, and synchronized control of all speakers in the system.

Since I bought the JBL LSR4312SP subwoofer to go along with my JBL LSR4328 Pack, it has been the ultimate combination for mixing music!

Finally I don't have to guess about my low end and I find my mixes come out much more balanced having this subwoofer! It's great for the fact it tunes itself to the room and works in harmony with the JBL 4328's. If your looking for a professional monitoring setup, this is the way to go. close [-]

Mike ConyersYour JBL monitor setup is not complete without a subwoofer and you'll want one that will be tuned to your room, right? Level up your studio with the LSR4312P subwoofer and start to REALLY hear your mixes! 
Ron DanielI recently added this sub to my studio's LSR speaker setup, and what a great addition it was! At the touch of a button, I'm now able to A/B with and without sub, as well as connect LFEs for DVD mixes. Certainly, my LSR4326s sound great on their own, but this was a great "next step" for my studio! I highly recommend it as "phase two" for your mixing environment. Also popular
