Architectual & Engineering Specifications

The compact sound reinforcement speaker system shall be a two-way type with a 12-inch low-frequency loudspeaker frontmounted in a ducted bass-reflex hardwood plywood enclosure with a compression driver mounted on a high-frequency horn which has a 1.4-inch throat, and a separate Control Electronics Unit.

The Control Electronics Unit shall contain a power supply capable of operating from a 120/240V AC, 50/60 Hz line, electronic crossover circuitry, electronic delay for the phase alignment of the low-frequency speaker, low- and highfrequency sliding filters which automatically activate under high power conditions, RMS limiters which protect the speakers from over-heating, equalization circuitry, active balanced input, indicator LED’s for power on and limiters. Total harmonic distortion shall be less than .1%. “A”- weighted noise level shall be at least 110 dB below maximum rated output of +26 dBu.

The speaker system, its companion Control Electronics Unit, and a power amplifier rated at 250 watts/channel into 8 ohms shall meet the following performance criteria: Frequency response, 80 Hz to 18 kHz plus or minus 4 dB measured with 1ž3 octave pink noise, 1 meter on axis; output of 125 dB SPL measured 1 meter on axis with peaks of 132 dB SPL driven with “A”-weighted noise. Total harmonic distortion shall be less than 1% at 110 dB SPL and 3% at 120 dB SPL one meter on axis. Distribution pattern, 80 degrees horizontal by 60 degrees vertical.

Speaker dimensions shall be 14.5″ W x 22.4″ H x 14.5″ D, weight 67 lbs (30 kg).

Control Electronics Unit dimensions shall be 19″ W x 1.75″ H x 7.75″ D, weight 8 lbs (3.6 kg).
