McCauley Sound's M421 has a continuous power handling in excess of 12,000W and measured peak output of 143 dBSPL at 4 m ground-plane within its operating band. With a well-shaped response from 20 to 100Hz and a total weight under 500 lbs, the M421 delivers an unprecedented level of low frequency energy for its size. The M421's design features four, independently powered, 21" long excursion neodymium motor transducers. Specially designed 6.0" voice coils exhibit near linear force factor (Bl) through the entire range of cone motion. The drivers are configured in an isobaric assembly and coupled to an FEA optimized acoustic transformer. With integrated handles, casters, skids, travel dolly, and optional fly ware, the M421 is a versatile and powerful sound reinforcement subwoofer.
The enclosure is constructed of multi-ply void-free birch hardwood plywood and is coated with a weather and wear resistant ProCoat™ polyurethane hybrid finish. Components in the front of the enclosure are protected by a flat grill made from perforated 11 gauge steel that is coated with heat cured epoxy powder. All rigging and hardware is weather protected with a heat-cured epoxy powder coat finish.
