Jbl LSR310S

The 10'' LSR 310 S subwoofer expands the LSR series, pairing perfectly with both the 5-inch LSR 305 and 8-inch LSR 308 monitors. It features a 200W Class D amplifier that delivers 113 dB SPL. The new proprietary JBL Slip StreamT Port technology works in sync with the driver to produce deep, precise bass at any volume level. The built-in XLF technology allows you to adjust the crossover and emulate the type of low frequencies used for dance tracks played in most clubs.
