M218

Heavy duty construction
Low profile, space optimized design
Laminar vents
Integrated locking feet
Designed with Cardioid Sub Arrays (CSA) in mind

OVERVIEW

The M218 is a high efficiency, high performance sub-bass loudspeaker with exceptionally high power handling. The M218 features two long excursion, high power handling 18” cone drivers mounted in a mechanically and acoustically optimized bass reflex cabinet with laminar venting. Port turbulence is virtually eliminated and distortion is minimized at high drive levels via a large, flared, symmetrical laminar vent.
The M218 enclosure was designed with both portable use and installation in mind. It features the option of up to 24 integrated fly points and optional array frames that allow for mounting to ceilings and the creation of traditional and cardioid flown arrays. The compact profile allows the M218 to fit easily under stages or up tight to ceilings.

The enclosure is constructed of premium birch hardwood plywood and is coated with a weather and wear resistant urethane hybrid finish. Components in the front of the enclosure are protected by a steel grill made from perforated steel that is coated with heat cured epoxy powder and lined with acoustically transparent foam. All optional rigging components are weather and corrosion protected with a heat cured epoxy powder coated finish.
