Subwoofer, Dual 18"
4050W  /  32Hz - 150Hz
The M882i is a high efficiency, high power handling sub-bass loudspeaker designed specifically for permanent installations. The M88i features two McCauley 8251 18” cone drivers mounted in a mechanically and acoustically optimized bass reflex enclosure with large vent area to reduce port turbulence.
The 8251 incorporates McCauley Sound’s latest long excursion neodymium motor with an industry first hybrid paper composite cone. The 8251 motor has an FEA optimized Bl vs. displacement profile to improve linearity and reduce distortion, a large aluminum heat sink, and 4” aluminum voice coil to improve power handling. The new cone body balances high stiffness with the internal damping that is inherent to paper cone loudspeakers, leading to a low distortion punchy sound even at high power levels.
The M882i enclosure was designed with installation in mind. It features 24 integrated fly points and optional array frames that allow for mounting to ceilings and the creation of traditional and cardioid flown arrays.

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.
