The M118 is a high efficiency, high impact sub-bass loudspeaker with exceptionally high power handling. It provides high impact, high sensitivity, low thermal compression and incredibly low distortion, even at the highest drive levels. These combined properties deliver the sonic qualities of precision and musicality.
The M118 features one long excursion, high power handling 18” cone loudspeaker mounted in a mechanically and acoustically optimized bass reflex cabinet with laminar venting. Port turbulence is virtually eliminated, and high drive level distortion is minimized via large, flared, symmetrical laminar venting. It operates from 35 Hz to 100 Hz when flown and from 32 Hz to 90 Hz when used as a general ground support subwoofer.
The M118 enclosure was designed with live performances and easy handling in mind. The compact profile allows the M118 to fit easily under stages, or stack in multiples up to 4 units. Multiple ergonomic handles on each side facilitate easy stacking and movement.
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.
The optimum processed loudspeaker solution for the RMS-ACOUSTICS SB subwoofer family are the RMS-ACOUSTICS series of processed amplifiers, also the Linea Research C and M series amplifiers, with proprietary presets provided by RMS-ACOUSTICS.
