JBL Patented Slip Stream Port

This patented JBL port design works in concert with the woofer’s low frequency driver for deep, dynamic bass response at all playback levels. The double-flared shape of the port is precisely calculated to optimize low-frequency extension.

XLF Extended Low Frequency Setting

A JBL first, the XLF setting activates a specially-engineered tuning that emulates the ample bass tuning used in today's dance clubs. When producing a dance track, the XLF setting will inspire you and bring a bit of the club to your control from. For inspiration to the max, position the LSR310S Subwoofer in the nearest corner of your room and activate the XLF setting.

Custom 10-inch Down-Firing High Excursion Low Frequency Driver

Professional Balanced Inputs and Outputs

Thanks to the balanced XLR and 1/4-inch inputs and XLR outputs, you can add the powered subwoofer to any studio monitor system to extend its low frequency performance or use it as the '0.1' LFE Channel in a surround sound system.

Selectable Input Sensitivity

The -10dBV/+4 dBu sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the unit to high-output professional equipment without any danger of input overload.
