• Low frequency loudspeaker system

• Optimized for permanent installation only

• 3x direct radiating 12-in woofers

• Optimized to array with MQ1364, MQ1366 and MQ1394

The new MQ Series represents the next generation of permanent installation loudspeaker systems. The Series comprises matched sets of mid/high and low frequency enclosures that enjoy complementary dimensions and trapeziod angles to facilitate the creation of optimized-coverage arrays. The MQ1312 uses three direct radiating 12-in woofer cones in an optimally tuned, vented enclosure.

The MQ1312 low frequency module works with the MQ1364, MQ1366 and MQ1394 mid/high modules to create arrays for use in a wide variety of permanently installed applications.

The most common array configuration is 2x MQ1364’s or MQ1366’s separated by a single MQ1312. In such an array, a certain amount of splay must be provided to achieve optimal coverage.

When arraying 2x MQ1394’s separated by a single MQ1312, the modules should be tight packed to achieve optimal coverage. This provides an excellent center channel array for large, fan-shaped venues that use an L/C/R configuration.

All MQ Series enclosures feature a comprehensive system of 3/8”-16 threaded mounting points for maximum flexibility when suspending arrays overhead.

Applications include:

A & E SPECIFICATIONS

The low frequency loudspeaker systems shall incorporate 3x 12-in LF transducers. The LF drivers shall be mounted in separate vented subenclosures tuned for optimum low frequency response.

System frequency respon se shall vary no m ore than ±3 dB from 50 Hz to 1600 Hz measured on axis. Th e loudspeak er shall produce a Sound Pressure Level (SPL) 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 137.8 SPL on axis at 1 meter. The loudspeaker shall handle 1500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 3x 8 Ohms. The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 1/2-in thi ckness void-free cross-gr ainlaminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black polyurethane. Input connectors shall be a 6-terminal barrier strip and 2x Neutrik NL4 Speakon with connections as follows (LF1 is topmost driver, LF3 is lowest):

NL4 (left) NL4 (right) Pins 1 +/– LF1 +/– LF3 +/– Pins 2 +/– LF2 +/– LF4 N/C

A total of sixteen 3/8"-16 threaded mounting/suspension points (4 each top, bottom, sides) shall be pr ovid ed. Th e fron t of the loudspeak er shall be cover ed with a powd er coated perforated steel grille.

The low frequency loudspeaker shall be the EAW model MQ1312.

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