• System includes an 8-in woo fer and a 1-in e xit/1.5-in voi ce coil compression driver on a 120° x 60° CD horn

• Internal passive crossover/filter network allows powering by a single amp channel while smoothing power response

• Beamwidth optimized crossover points eliminate off-axis voids through crossover

• User-rotatable horn lets you “rotate the enclosure around the horn” to mount them vertically or horizontally

The MK8126 two-way loudspeaker system sets the new standard in installation performance by solving the chronic problems of compact two-way loudspeakers. Yet it’s size is actually smaller than many o f the compact two-ways it outperf orm s.

The HF horn loading the 1-in exit/1.5-in voice coil compression driver is larger than most traditional compact two-way horns. This extends pattern control lower into the midrange than would otherwise be possible and allows the horn’s pattern to overlap the woofer’s pattern in the critcal crossover area.

Advanced beamwi dth m atching crossover poin t selection tr ansitions between the subsystems exactly where the HF horn’s 120° (h) x 60° (v) coverage pattern matches the woofer’s pattern.

This eliminates the beamwidth mismatch that creates

off-axis voids in the crossover area of traditional two-way systems. The internal passive crossover/filter network uses complex,

asymmetrical slopes to integrate the subsystems and goes beyond merely dividing the signal to perform critical equalization functions.

The MK8126 provides a high performance solution to applications requiring the use of an ultra-compact two-way loudspeaker system. Ideally suited to distributed approaches, these small, powerful sytems m ount easily in a variety o f locations and provide consistent coverage over the entire frequency range.

MK Series HF horns feature a square flange allowing the user to rotate them 90°. This way, the systems can be mounted horizontally while maintaining the desired coverage pattern. And the comprehensive system of 3/8”-16 threaded mounting/suspension points permit the enclosures in any orientation.

DIMENSIONAL DRAWING

A & E SPECIFICATIONS

The two-way full range loudspeaker systems shall incorporate an 8-in LF transducers and a 1-in exit/1.5-in voice coil compression driver HF transducer.

The LF drivers shall be moun ted in an optim ally vented enclosure tuned for maximum low frequency response. The HF driver shall be loaded on a constant directivity horn with a nominal coverage pattern o f 120° (h) x 60° (v). The HF h orn shall feature a square flange allowing it to be rotated 90°. An internal passive filter network shall provide fourth order acoustical crossover and system equ alizati on between the low and high frequency sections.

System frequency response shall vary no more than ±3 dB from 89 Hz to 18 kHz measured on axis . Th e system shall produce a Sound Pressure Level (SPL) of 95 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 125.8 dB SPL on axis at 1 meter. The system shall handle 300 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of exterior grade Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in wear resistant te xtured black pain t. Input conn ectors shall be two-terminal barrier strip. A total of 13x 3/8"-16 threaded mounting/suspension points (3 each top and bottom, 3 per side and 1 back) shall be provided. Four additional mounting points shall be provided on the rear configured to accept an Omnimount brand Series 100 bracket. The front of the loudspeaker shall be cover ed with a powder coated perforated steel grille.

The 2-way full range loudspeaker shall be the EAW model MK8126.

Manufacturing tolerances are +/- 0.13 and +/- 1°
