Country of Origin (driver): China
Meets or exceeds industry standards

The 8-inch coaxial (50W) driver with mounted transformer shall be Lowell Model No. 8A50-TM1670-S which shall be of the coaxial type having electrically independent high and low frequency transducers. The low frequency section shall have an 8″ diameter polypropylene cone and the high frequency section shall have a tweeter with a 1″ balanced-drive dome. A built-in electrical crossover network shall be employed to accomplish the proper frequency division between the 2 drivers. Crossover frequency shall be at 4000Hz with a first order high-pass filter. Power rating shall be 50 watts RMS. The low frequency voice coil shall have a diameter of 1.4″ and operate in a magnetic field derived from a ferrite (ceramic) magnet with nominal weight of 3.5 lbs. The high frequency voice coil shall have 0.53″ diameter and operate in a magnetic field derived from a ferrite (ceramic) magnet with 2 oz. nominal weight. Voice coil impedance shall be 8 ohms. The driver shall have a round, structurally reinforced stamped 20-ga. steel frame with 8.08″ overall diameter and 8 obround holes equally spaced at 45 degrees on 7.625″ diameter mounting bolt circle. External metal parts shall be finished in black enamel coating or zinc plating to resist rust and corrosion. The mounted transformer shall be 70V with primary taps at 4, 8, and 16W. The assembly shall be capable of producing a uniform audible frequency response over the range of 40Hz-17.4kHz (±6dB) and 40Hz-20kHz (±11.4dB) with a dispersion angle of 90 degrees conical @2000Hz-6dB. Average sensitivity shall measure 90.8dB (SPL at 1W/1M). Overall depth shall not exceed 4.1″.
