Subwoofer, Dual 18"
35Hz - 150Hz
The M88 is a high efficiency, high power handling loudspeaker designed for touring sound sub-bass applications. The M88 features two, 4” voice coil, long excursion 18” cone drivers mounted in a mechanically and acoustically optimized bass reflex enclosure. The cone driver incorporates McCauley Sound’s latest FEA optimized neodymium motor with a new hybrid paper composite cone body for increased linearity and lower distortion at high output levels. The M88 enclosure features a large vent area for decreased port turbulence and integrated handles and casters which allow for easy setup, loading and transportation.

The enclosure is constructed of multi-ply void-free birch hardwood plywood and is coated with a weather and wear resistant ProCoat™ polyurea hybrid finish. All rigging components are weather protected with a heat cured epoxy powder coat finish. Components in the front of the enclosure are protected by a flat grill made from perforated steel that is coated with heat cured epoxy powder, and lined with acoustically transparent foam.
