DESCRIPTION
EAW’s MK2264 two-way loudspeaker system provides high
output, low distortion sound reinforcement for a wide range
of permanently installed audio applications.
The 12-in low frequency cone and 1.4-in exit/75mm voice
coil high frequency compression driver provides higher out-
put and lower distortion plus enhanced power handling ca-
pabilities.
EAW’s advanced beamwidth matching crossover selects a
crossover point where the HF horn’s beamwidth matches that
of the woofer. The result is more even off-axis frequency
response (power response) for more complete coverage.
The MK2264 is a biamplified loudspeaker requiring the use
of pre-configured MX Series processor settings.
APPLICATION
The MK2264 was designed to support the widest possible
range of permanent installations and was optimized for use
in distributed systems.
Its high output capabilities let it cover a large seating area
in such applications as houses of worship, themed enter-
tainment venues, arenas, stadiums and nightclubs.
The comprehensive system of integral 3/8”-16 threaded
mounting points permit safe, load-rated suspension.

DIMENSIONAL DRAWING ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate 12-in LF transducer and a 1.4-in exit/75mm 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 constant directivity horn with a nominal coverage
pattern of 60°(h) x 45°(v).
System frequency response shall vary no more than ±3 dB
from 70 Hz to 19 kHz measured on axis. The low frequency
section shall produce a Sound Pressure Level (SPL) of 97 dB
SPL on axis at 1 meter with a power input of 1 Watt, and
shall be capable of producing a peak output of 130 dB SPL
on axis at 1 meter. The high frequency section shall produce
a Sound Pressure Level (SPL) of 109 dB SPL on axis at 1
meter with a power input of 1 Watt, and shall be capable of
producing a peak output of 138 dB SPL on axis at 1 meter.
The low frequency section shall handle 500 Watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 8 Ohms. The high frequency section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 16 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic Birch plywood and shall employ extensive
internal bracing. It shall be finished in wear-resistant tex-
tured black paint. Input connector shall be a 2x 2-terminal
barrier strip. The following mounting hardware shall be pro-
vided: A total of thirteen 3/8” 16-threaded mounting points
(three each on top and bottom, two per side, three on rear)
shall be provided. The front of the loudspeaker shall be cov-
ered with a powder coated perforated steel grill.
The two-way full range loudspeaker shall be the EAW model
MK2264.
