The FBT PROJECT SUB 1020SA powered subwoofer enhances low frequencies in sound systems featuring speakers from the PROJECT series. It includes a 10″ driver with a polypropylene cone and long-excursion suspension, along with a 150 W RMS Class D amplifier. The bass-reflex cabinet is made of MDF and has a scratch-resistant finish.

The stereo XLR/TRS inputs are balanced, while the RCA inputs are unbalanced. The stereo XLR outputs feature an adjustable high-pass filter, while the low-frequency cutoff point and phase can be adjusted using the corresponding controls. Standby mode reduces power consumption during periods of inactivity.
