Horizontal 1/3 Octave Polars Architectural Specifications: The loudspeaker shall consist of a 165 mm (6.5 in) low frequency transducer, with a coaxial 19 mm (3/4 in) high frequency transducer. The low frequency drivers voice coil shall be 25 mm (1 in) in diameter. Performance specifications of a typical unit shall be as follows: Usable frequency response shall extend from 70 Hz to 20 kHz (10 dB below rated sensitivity, half-space, no external equaliza- tion – in recommended backcan). Rated power shall be 60 watts continuous pink noise power (conforming to IEC268-5 test parameters) for 100 continuous hours. Measured sensitivity shall be at least 89 dB-SPL (at 1m [3.3 ft] with 60W input, avg. 100 Hz to 10 kHz). The input shall have an included transformer for a 70.7V or 100V distributed speaker line. Selectable taps shall nominally be 60W, 30W, or 15W on a 70.7V or 100V distributed line, plus 7.5W on 70.7V line only. The coaxial high frequency driver shall be diffraction-loaded and cover 90 degrees conically with a high degree of accuracy. The loudspeaker assembly shall be capable of attachment to any backcan that corresponds to a 7.625 in diametric spacing of screw holes. It shall also be capable of attachment to any grille that meets the same hole pattern. The low frequency transducer shall have a polypropylene- coated cone and a pure butyl rubber surround for long life and relia- bility. The high frequency transducer shall have a polyester diaphragm that is coated with titanium and diffraction loaded. The transducer assembly shall have a barrier strip for both safety and good reliable conductor connection. Overall assembly dimensions shall be no greater than 120 mm high x 200 mm diameter (4.72 in x 7.87 in) and shall weigh no more than 1.9 kg (4.2 lb). The system shall be the JBL Model Control 26-DT.
