FBT Q 118SA Active Subwoofer

FBT Q 118SA Active Subwoofer

FBT Q 118SA is an active 18-inch subwoofer with a built-in Class D amplifier and DSP.

The bass-reflex cabinet extends larger Q-series sound systems. Stereo XLR inputs and link outputs support integration with left and right audio channels.

A 18-inch woofer with a 4-inch voice coil is driven by an amplifier rated at 1200 W maximum RMS. FBT specifies 30–100 Hz frequency response at -6 dB.

DSP offers six EQ presets and six delay steps. The rear panel adds level and 0°/180° phase controls, while two M20 pole sockets sit on top.
