A18SUB is a horn-loaded low frequency enclosure

A18SUB is a horn-loaded low frequency enclosure
A18SUB is a horn-loaded low frequency enclosure
featuring proprietary symmetric loading (patent pending).
As a horn-loaded design A18SUB is able to maintain
high efficiency and extremely fast peak response with
low distortion even at high sound pressure levels.
A18SUB features single 18” long excursion neodymium cone driver. Unique enclosure design also enables the use of 15mm birch plywood still maintaining
rigidity with free of unwanted vibrations. This makes the
enclosure lighter than average without using fibre-class
or other composite materials.
A18SUB is equipped with heavy duty wheels, ABS
handles and large corner mouldings for easy and safe
ground stacking.
Keep the pressure in sound, not on your back!
