RECOMMENDED AMPLIFIERS

MONSTER !

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. 

 

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.

Check the curves!

Its only a graph but…..  feel it!
