MQTD415/888174 Rev(1)/2 pp 7/25/00
Printed in USA
The low frequency loudspeaker systems shall incorporate 2x
15-in plus 2x 12-in LF transducers. Each driver pair shall be
spaced so as to create a tuned dipolar array. The driver pairs
shall require an active crossover at 145 Hz, 24 dB/octave. The
system shall provide 10-12 dB attenuation 90° off axis from
110 Hz to 300 Hz.
System frequency response shall vary no more than ±3 dB
from 48 Hz to 300 Hz measured on axis. The 15-in driver pair
shall produce a Sound Pressure Level (SPL) of 101 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 139 SPL on axis at 1
meter. The 15-in driver pair shall handle 1600 Watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 2x 8 Ohms.
The 12-in driver pair shall produce a Sound Pressure Level
(SPL) of 101 dB SPL on axis at 1 meter with a power input of
1 Watt, and shall be capable of producing a peak output of
137 SPL on axis at 1 meter. The 12-in driver pair shall handle
1000 Watts of amplifier power (AES Standard) and shall have
a nominal impedance of 2x 8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 1/2-in 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 connectors shall be dual four-termi-
nal barrier strips. A total of 16 3/8"-16 threaded mounting
points (4 each top, bottom, and sides) shall be provided. The
front of the loudspeaker shall be covered with a powder coat-
ed perforated steel grille.
The low frequency loudspeaker shall be the EAW model
MQTD415.
Manufacturing tolerances are +/- 0.13 and +/- 1°
