The MR-2153 is three-way full range loudspeaker systems. Shall incorporate two 15＂LF transducer and a 1" exit/44mm voice coil compression driver HF transducer, the LF driver shall be mounted in a vented enclosure tuned for optimum low frequency response.

The HF driver shall be loaded on an axis-symmetrical wave guide plate with a nominal coverage pattern of 90° × 50°. An internal passive filter network shall provide fourth order acoustical crossover and system equalization. System frequency response shall vary no more than(-3dB) from 55Hz to 19KHz measured on axis.

The loudspeaker shall produce a sound pressure level(SPL) of 99dB SPL on axis at 1 Meter with a power input of 1 watt, and shall be capable of producing a peak output of 132dB SPL on axis at 1 metre.

The loudspeaker shall handle 600 watts of amplifier power and shall have a nominal impedance of 4 Ohms.

The loudspeaker enclosure shall be irregularly trapezoidal in shape. Rubber footpads shall be provided on one end. It shall be constructed of 18mm thickness MDF plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be dual Neutric NL4 Speakon. The front of the loudspeaker shall be covered with a vinyl coated perforated steel grill.
