The EMS-112 is a compact, powerful subwoofer, intended to support the smaller fullrange loudspeakers from the EMS Series. The compact enclosure is constructed from 15mm (5/8”) Baltic birch plywood, and houses a single 4” voice coil, 12” (305mm) high-excursion LF drive unit. The enclosure includes a single M20 threaded polemount adapter – allowing the mounting of EMS series fullrange loudspeakers above. As standard the EMS-112 is fitted with rubber feet underneath and matching recesses on top to allow stable stacking of multiple enclosures, and two flush handles are provided on the sides. Three NL4 connectors are provided on a recessed panel at the rear - two for input and enclosure link, and a third for the separate highpass filtered output. Lastly, a tough hex punched steel grille protects the drive unit from damage whilst in use or in transit. The enclosure is finished in black or white textured paint as standard, though RAL colour matching and weather protection options are available. 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 optimal results, either the DQ Series Advanced System Amplifiers, or the AQ or AD Series amplifiers combined with DSC48 processors should be used.
