A&E SPECIFICATIONS

The driver shall be Lowell Model No. 6A40, 6A40 which shall be of the coaxial type having electrically independent high and low frequency transducers. The low frequency section shall have a 6.5 inch diameter polypropylene cone and the high frequency section shall have a tweeter with a 1 inch balanced-drive dome. A built-in electrical crossover network shall be employed to accomplish the proper frequency division between the two drivers. The crossover frequency shall be at 4000Hz with a first order high-pass filter. The driver shall be capable of producing a uniform audible frequency response over the range of 40Hz-20kHz (±6dB) with a dispersion angle of 120 degrees conical @2000Hz (-6dB). The average sensitivity shall measure 85dB (SPL at 1W/1M). Rated power handling shall be 40 watts RMS. The low frequency voice coil shall have a diameter of 1 inch and shall operate in a magnetic field derived from a ferrite (ceramic) magnet having a nominal weight of 10 oz. The high frequency voice coil shall have a diameter of 0.53 inches and operate in a magnetic field derived from a ferrite (ceramic) magnet having a nominal weight of 2 oz. The voice coil impedance shall be 8 ohms. The driver shall have a round, structurally reinforced stamped 20 ga. steel frame to maintain precise mechanical alignment and shall provide facilities for mounting a transformer. The driver shall have an overall diameter of 6.5 in. with eight obround holes equally spaced at 45 degrees on a 6.13 in. diameter mounting bolt circle. The mounting depth shall not exceed 3 in. (not including optional transformer). External metal parts shall be finished in black enamel paint or zinc plating.
