The amplified loudspeaker system shall be a self-

contained unit, housed in a reinforced polypropylene 

enclosure and consisting of the following sub-sys-

tems: (1) vented two-way loudspeaker system, (2) 

integrated power amplifiers and crossover network, 

(3) integrated mic/line input with music and voice 

equalizers.

The loudspeakers shall consist of a 15 inch low-

frequency, cone driver, with at least a 3 inch voice 

coil, and an 80° x 60° high-frequency, constant-

directivity polynomial horn with a horn-loaded, 

2 inch compression driver having a titanium dia-

phragm and compensated for horn resonance and 

ringing. The drivers shall be aligned with an analog 

circuit and crossed over at 1.2kHz by a 4-pole network 

built into the power amplifiers. Together they shall be 

capable of producing 126dB SPL (1m, anechoic).

Two discrete amplifiers shall be provided, 

capable of continuously delivering 400W RMS to 

the low-frequency driver and 100W RMS to the high-

frequency driver. Distortion shall be less than 0.1% 

when measured at 1kHz and 10kHz. They shall be 

equipped with a multi-function protection circuit to 

peak limit and protect the loudspeakers from over-

heating, over-excursion, overloads, short circuits 

and extreme operating temperatures. An indicator 

light shall illuminate when any aspect of the protec-

tion circuit engages.

The integrated mic/line input shall be actively 

balanced, may also accept an unbalanced input, and 

shall be paralleled to an output. Both shall have XLR 

connectors. The input shall have a switch to select 

between 10mV mic and 775mV line levels. The unit 

shall be provided with both voice and music optimi-

zation equalization that can be activated with but-

tons on the rear panel. The voice equalizer shall pro-

vide +4dB at 3kHz and +4db at 6kHz. The music 

equalizer shall provide +4dB at 65Hz and +4dB 

at 12kHz. A continuously variable, rotary master 

volume control shall be provided.

The power supply shall be internal and con-

nected to 50 or 60Hz source current through a 

detachable IEC power cord and shall have an IEC 

socket for mains power loop-through. It shall have 

an on/off switch, fuse holder and threaded ground-

ing screw on the rear panel. AC voltage shall be 

selectable between 115 and 230VAC. The power 

supply shall draw a maximum of 5A and illuminate 

an indicator light when on.

The reinforced polypropylene enclosure shall 

have a volume of at least 2.64 cu. ft., be trapezoidal 

shaped and equipped with a grille to protect the 

cone driver. At least four M10 and two M8 threaded 

sockets and stand socket shall be molded into the 

cabinet for attaching mounting hardware, designed 

for the unit and available from the manufacturer. 

The amplified loudspeaker system shall be a model 

ART500A manufactured by Mackie Industrial.
