EAW MQ1215 User manual

• Low frequency array module
• Two 15 inch woofers
• Engineered to array with MQ1300 MF/HF modules
• For permanent installation only
• Digital signal processor required for specified performance
The MQ1215 uses two direct radiating 15 inch cones mounted
in a vented trapezoidal enclosure. Its frequency response has
been optimized for use as a dedicated low frequency system
when used with a companion MQ mid/high loudspeaker. Each
driver has its own connections on the input panel. This allows
the drivers to be connected in parallel to one amplifier chan-
nel or connected individually to separate amplifier channels.
The enclosure features a comprehensive system of 3/8-16
threaded suspension points.
The MQ Series comprises matched sets of mid/high and low fre-
quency enclosures with complementary dimensions. This facil-
itates creating attractive arrays that provide high definition
sound within tightly controlled coverage areas. The MQ1215 is
designed to work with a complementary MQ1300 Series
mid/high loudspeaker to create a full range audio system. The
enclosure is vertically configured for arraying in horizontal
rows. Horizontal arrays are typically used in venues where the
array must address wide, fan-shaped audiences.
The most common array configuration is two MQ1364e's or
MQ1366e's separated by a single MQ1215. In such an array, the
MQ1364e's or MQ1366e's should be splayed 25° to either side
of the MQ2315, netting a splay angle of 50° between mid/high
modules. When arraying two MQ1394e's separated by a single
MQ1215, all enclosures should be tight-packed to achieve opti-
mal coverage. This configuration will net a splay angle of 80°
between mid/high modules. All splay angles reference the cen-
ter line of the enclosures.

The low frequency loudspeaker system shall incorporate two
15 inch LF transducers. The LF drivers shall be mounted in
separate vented subenclosures tuned for optimum low fre-
quency response.
System frequency response shall vary no more than ±3 dB from
50 Hz to 1300 Hz measured on axis. The loudspeaker shall
produce a sound pressure level of 100 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 SPL on axis at 1 meter. The
loudspeaker shall handle 2x 800 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 exterior grade Baltic birch plywood
and shall employ extensive internal bracing. It shall be fin-
ished in wear resistant textured black paint. Input connectors
shall be a 4-contact barrier strip and 1x Neutrik NL4 Speakon.
A total of sixteen 3/8"-16 threaded mounting/suspension
points (4 each top, bottom, sides) shall be provided. The front
of the loudspeaker shall be covered with a powder coated per-
forated steel grille.
The low frequency loudspeaker shall be the EAW model
MQ1215.
Manufacturing tolerances are +/- 0.13 and +/- 1°
