Model CT830A

High performance 8-inch 20W coaxial driver features a post-mounted, coaxially positioned tweeter for improved performance over a traditional full-range (dual cone) driver. The 3 inch tweeter provides wide dispersion in the high frequency range enhancing speech/music intelligibility in the area between speakers. Outstanding choice for quality paging, public address, and background music.

The 8 inch speaker driver shall be Lowell Model CT830A which shall be of the coaxial type having electrically independent high and low frequency transducers. The low frequency section shall have an 8 in. diameter cone; the high frequency section shall have a 3 in. diameter cone. A built-in electrical crossover network shall be employed to accomplish proper frequency selection between the two drivers. Crossover frequency shall be at 4000Hz. The speaker shall be capable of producing a uniform audible frequency response over the range 57Hz-14kHz (±6dB) and 44Hz-20kHz (±7.6dB) with dispersion angle of 80 degrees conical@2000Hz (-6dB). Average sensitivity shall measure 97.0dB (SPL at 1W/1M). Power rating shall be 20 watts RMS. The low frequency voice coil shall have a 1″ diameter and shall operate in a magnetic field derived from a strontium ferrite (ceramic) magnet having a nominal weight of 12 oz. The high frequency voice coil shall have a 0.57″ diameter and operate in a magnetic field derived from a strontium ferrite ceramic magnet having a nominal weight of 2.1 oz. Voice coil impedance shall be 8ohms. The speaker shall have a round, structurally reinforced stamped 20-gauge steel frame for precise mechanical alignment and shall provide facilities for mounting a transformer. It shall have an overall diameter of 8.062 in. and eight obround holes equally spaced at 45 degrees on a 7.625 in. diameter mounting bolt circle. Overall depth shall not exceed 3.2 in. External metal parts shall be zinc-plated to resist rust and corrosion.
