Our passive, single 18" folded horn subwoofer delivering a massive 141dB (max SPL) .

Delta F18B is supplied with castors so is a surprisingly portable and easily moveable enclosure.  Where significant extension of low frequency output of a sound system is required over middle-long distances the addition of one or more Delta F18B subwoofers will provide high output low frequency enhancement to the overall sound system.

The folded horn design enables the Delta F18B to deliver ground shaking low frequencies over long distances (Unlike direct radiating designs which provide near to middle distance sound).

The Delta F18B is designed to work with an external, active crossover unit.
