The three-way full range loudspeaker systems shall incorpo- rate a 15-in LF transducer, an 8-in MF transducer and a 1.4- in exit/1.75-in voice coil compression driver HF transducer.

The LF driver shall be mounted in a vented enclosure tuned for optimum low frequency response. The MF driver shall be loaded into a midrange horn constructed of 1/8-in birch ply- wood reinforced with high density polyurethane foam. The MF horn shall incorporate a phase/displacement plug. The HF driver shall be loaded on a constant directivity horn with a nominal coverage pattern of 60° (h) x 45° (v).

Powering mode shall be switchable between full range pas- sive and bi-amplified operation. In full range passive mode, an internal passive filter network shall provide fourth order acoustical crossover and system equalization between the low, mid and high frequency sections. In bi-amplified mode, an internal passive filter network shall provide fourth order acoustical crossover and system equalization between the low and mid frequency sections.

System frequency response shall vary no more than ± 3 dB from 62 Hz to 20 kHz measured on axis. The full range sys- tem 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 low/mid section in bi-amplified mode shall pro- duce 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 in biamplified mode shall pro- duce a Sound Pressure Level (SPL) of 108 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 136 dB SPL on axis at 1 meter. The full range system shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The low/mid section in biamplified mode shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The high frequency section in biamplified mode shall handle 150 Watts of am- plifier power and shall have a nominal impedance of 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 black catalyzed poly- urethane. Input connectors shall be 2x Neutrik NL4 Speakon.

Atotal of 3x 3-position flytracks with integral 3/8"-16 threaded mounting points (2 top and 1 back) shall be pro- vided. The front of the loudspeaker shall be covered with an arced, vinyl-coated, perforated steel grille.

The 3-way full range loudspeaker shall be the EAW model LA460.
