The driver shall be Lowell Model 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.
