Ported design means more accuracy at low volume levels
Checking your mix at low volume levels is a great way to check your overall balance, but many speakers will suffer in the bass regions when dealing with low monitoring levels. The JBL LSR310S uses JBL's patented "Slip Stream" low-frequency port for accurate bass response at low playback levels. The double-flared port shape also reduces the turbulence that some ported designs cause, meaning that bass response remains pure when you turn the LSR310S back up.
All the connections you need for your studio
The JBL LSR310S active subwoofer is packed with the professional features such as balanced XLR inputs, balanced 1/4" inputs, selectable crossover settings, and balanced XLR outputs to allow connection of left and right main speakers. A level control allows independent adjustment of the subwoofer output to balance the sound of your studio monitor system.
