A & E SPECIFICATIONS
The three-way, two channel extended range loudspeaker sys-
tem shall incorporate (per channel): a 15-in sub bass trans-
ducer, 2x 6.5-in LF transducers and a 1-in exit/1.75-in voice
coil compression driver HF transducer. The total system shall
incorporate two full range enclosures and two sub bass en-
closures.
Each sub bass driver shall be mounted in a vented enclosure
tuned for optimum low frequency response. Each sub bass
enclosure shall house an internal passive filter network pro-
viding sub bass/full range crossover. Each pair of LF drivers
shall be mounted in a vented enclosure which also houses a
HF driver. Each full range enclosure shall house an internal
passive filter network providing LF/HF crossover. Each HF
driver shall be mounted on an axis-symmetrical wave guide
plate. The total system’s nominal coverage shall be 100
°
(h)
x 80
°
(v).
System frequency response shall vary no more than
±
3 dB
from 43 Hz to 19 kHz measured on axis. In passive mode,
the loudspeaker shall produce a Sound Pressure Level (SPL)
of 94 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
127 SPL on axis at 1 meter. It shall handle 500 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 8 Ohms.
The sub bass enclosures shall be rectangular in shape. The
full range enclosures shall be trapezoidal in shape. All enclo-
sures shall be constructed of 1/2-in thickness void-free cross-
grain-laminated Baltic birch plywood and shall employ ex-
tensive internal bracing. They shall be finished in black cata-
lyzed polyurethane. A switch allowing the user to choose
between passive and bi-amped powering modes shall be in-
stalled on the back of each sub bass enclosure.
Input connectors on each sub bass enclosure shall be 3x
Neutrik NL4 Speakon (1 input, 1 loop-through, 1 output to
full range satelite). Input connectors on each full range en-
closure shall be 2x Neutrik NL4 Speakon. (1 input, 1 loop-
through). A total of six 1/4"-20 threaded mounting points
(1 each top and bottom, plus 4 on back to accept an
Omnimount Series 100) shall be provided on each full range
enclosure as well as two 5/16"-18 threaded mounting points
designed to accomodate an external standmount adapter.
The front of each enclosure shall be covered with a vinyl
coated perforated steel grille backed with open cell foam to
protect against dust.
The three-way, two channel extended range loudspeaker shall
be the EAW model MM80.
