FBT SUBLINE 112SA Active Subwoofer

FBT SUBLINE 112SA Active Subwoofer

The FBT SUBLINE 112SA is an active 12-inch bass-reflex subwoofer.

Its 700 W RMS Class D amplifier drives a low-frequency woofer with a 3-inch voice coil. The response extends from 40 to 140 Hz (-6 dB), with a specified peak SPL of 133 dB measured in half-space.

The onboard DSP offers 8 presets. Delay and phase reversal controls help align the subwoofer with the other loudspeakers in a sound system.

Stereo XLR inputs accept the source signal, and XLR link outputs pass it onward. The birch plywood cabinet has two aluminium handles and a top-mounted M20 pole socket.
