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 low frequency voice coil shall have a 1 in. diameter and operate in a magnetic field derived from a strontium ferrite (ceramic) magnet with nominal weight of 12 oz. The high frequency voice coil shall have a 0.57 in. diameter  and operate in a magnetic field derived from a strontium ferrite ceramic magnet with nominal weight of 2.1 oz. Voice coil impedance shall be 8ohms. The speaker shall have a structurally reinforced, stamped 20-gauge steel frame with 8.062\" overall dia. and eight obround holes equally spaced at 45 degrees on a 7.625 in. diameter mounting bolt circle. External metal parts shall be zinc-plated to resist rust and corrosion. The speaker shall have a mounted transformer with primary taps at 1, 2, 4, 8W @70V.The assembly shall be capable of producing a uniform audible frequency response over the range 53Hz-14.3kHz (±6dB) and 44Hz-20kHz (±7.1dB) with dispersion angle of 80 degrees @2000Hz (-6dB).Average sensitivity shall measure 97.1dB (SPL at 1W\/1M). Assembly mounting depth shall not exceed 3.3 in.\u003c\/p\u003e\n\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Lowell","offers":[{"title":"Default Title","offer_id":55657623388451,"sku":"CT830A-T870","price":84.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/5404\/5987\/files\/lowell-ct830a-t870-7.jpg?v=1790386039","url":"https:\/\/sixstardj.com\/products\/lowct830at870","provider":"SixStarDJ","version":"1.0","type":"link"}
