Frog-is FA-SUB21P

FA-SUB21P is a 21" passive subwoofer built for maximum low-frequency output in professional array systems.

Design Story

The FA-SUB21P houses a single 21-inch driver in a vented enclosure tuned for maximum output and lowest possible extension. Its passive design allows flexible amplifier pairing, while the robust touring-grade cabinet construction withstands the rigours of repeated transport and installation. An essential foundation for high-performance array systems requiring authoritative sub-bass.
