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.
4″ Voice coil
To deliver the ground shaking 141dB Max SPL, the Delta F18B features a custom designed 18″ transducer.
Using an aluminium die-cast basket, this transducer has a massive 4″ voice coil which handles up to 3200w peak power.
Simply put, this custom Wharfedale Pro transducer is the heart of the F18B – giving it enormous low end power.
Folded horn design
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).
Internal baffles tune and guide the low frequencies to deliver more throw and bass distance than you have experienced before.
Hardware enclosure
The magic of the Delta F18B happens inside with its folded horn design but, externally, the F18B also features practical hardware features.
Delta F18B is supplied with four (4) sturdy and robust castors so is a surprisingly portable and easily moveable enclosure.
There are also 4 carry handles placed top and bottom to help move this subwoofer into the best location.
On the top surface there is even a standard 35mm pole socket allowing for a full range loudspeaker to be placed on a pole.
