The enclosure contains a single 4” (102mm) voice coil, 12” (305mm) high-excursion LF drive unit, and is constructed from premium grade multi-laminate Birch plywood and finished in impact resistant paint. The front of the subwoofer is protected by a rigid steel grille. Two flush handles, rubber feet and mating recesses and an M20 threaded pole adapter are provided for flexibility when in use. Three NL4 connections are provided on a recessed panel at the rear – two for input and enclosure link, and a third for the seperate high-pass filtered output. RAL colour matching and weather protection options are also available if required.

The EMS-112 can add low frequency power and extension to systems based around any EM Acoustics fullrange product, but is particularly suited to the smaller products within the range. The EMS-112 requires a single amplifier channel capable of delivering 800-1000W RMS into a 8 ohm load. For optimum results, the EM Acoustics DQ10 or DQ20 Advanced System Amplifiers, or the AQ-10 or AD-9 power amplifier in conjunction with the DSC48 system controller (for loudspeaker protection) should be used.
