Bringing extended low-frequency performance to music recording and post-production clients, Harman’s JBL Professional today introduces the new LSR310S powered studio subwoofer ($499 MSRP), optimized for use with JBL 3 Series studio monitors, which are the first studio monitors to incorporate JBL’s patent-pending Image Control Waveguide. Rounding out the 3 Series line, the new LSR310S subwoofer extends the low-frequency response of the system into the 20Hz range.

Driven by an integrated 200-watt Class-D power amplifier, a new 10-inch high excursion woofer works in concert with JBL’s patented Slip Stream Port, delivering low-frequency response below 27 Hz, with peak output of 113 dB SPL.

JBL recommends the LSR310S for use in music recording and playback reference systems, and also as the “.1” LFE Low Frequency Effects speaker in surround-sound post-production applications. The sub includes a selectable XLF Extended Low Frequency setting that emulates the augmented low-frequency response heard in the dance club environment. This provides a useful reference of how a dance mix will sound in the outside world.

Designed to integrate into a broad range of applications the LSR310S features balanced XLR and ¼-inch inputs, a selectable input sensitivity switch and three crossover settings: 80Hz, XLF and External. The 80 Hz setting implements high- and lowpass filters to create a seamless blend of the LSR310S with JBL’s LSR305 or LSR308 studio monitors or models from other manufacturers. The external setting bypasses all filtering, allowing use of an external crossover. The special XLF setting activates a 120Hz highpass filter in conjunction with a low frequency tuning that approximates the tuning used in club playback systems. Using this setting, the bass output more than doubles and the newly developed woofer/amp combination with protective limiting allow the 310S to produce extended bass output continuously without failure.

The LSR310S is highlighted by a distinctive glossy black flange of the front-mounted Slip Stream Port, an enclosure designed to fit neatly into small recording and post-production studio environments.
