I think this system is a real gem, and congratulations to Ed and Mike and all at EM Acoustics for having made it a reality.
The EMS-112 is a compact, powerful subwoofer, designed to complement the smaller fullrange products within the EMS Series – especially the EMS-51, EMS-61 and EMS-81X. The optimally-tuned vented enclosure provides excellent transient response and low frequency reproduction without the aid of corrective equalisation. The EMS-112 has the advantage of being completely passive – having both a low-pass filter for the subwoofer itself, and also a seperate high-pass filtered output for fullrange boxes. This makes the EMS-112 a truly self-contained system, enabling subwoofer and fullrange loudspeaker to be run from a single amplifier channel.
- High power to size ratio
- Premium 15mm multi-laminate birch plywood enclosure
- Black or white textured paint finish
- Optional weather protection or RAL custom colours
- M20 threaded pole mount adapter
- Hex punched steel grille
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.
