Footnotes:
Frequency response and range measured on-axis with recommended active EQ in an anechoic environment.
Power handling tested using pink noise filtered to meet IEC 268-5, 6 dB crest factor, 100 hours, with recommended EQ.
Sensitivity measured in free field (no boundary-loading gain) with recommended active EQ, referenced to 1W/1m.
Maximum SPL calculated from sensitivity and power handling specifications, exclusive of power compression.
Architects’ & Engineers’ Specifications
The low-frequency device shall be a dual-ported highly compact enclosure with matched active equalization as follows:
The transducer complement shall consist of one (1) high-power-handling driver of 12″ (305 mm) diameter, mounted inside an enclosure such that distortion is minimized as a result of acoustic filtering. Its operating frequency range shall be below 160 Hz so that non-localizability shall allow a high degree of location placement flexibility.
The input connector, located on the rear of the enclosure, shall be a screw-type barrier strip.
The enclosure shall be made of vinyl-wrapped, high-density wood composite, with outer dimensions of 31.0″ x 14.0″ x 15.5″ (787 mm x 356 mm x 394 mm); its weight shall be 85 lb (38.6 kg).
The bass enclosure’s maximum continuous acoustic output shall be 116 dB SPL from 50 Hz to 140 Hz, with measurements referenced to a full-bandwidth pink-noise input at 1 meter at the enclosure’s rated power. Its power-handling capacity shall be 450 watts continuous referenced to IEC noise for 100 hours.
The bass enclosure shall be the Bose® Panaray® 502® B Acoustimass® enclosure.
