Speaker Driver #JR410 (4? 15W single cone)

Speaker driver JR410 is a commercial industry standard 4 inch (EIA 5 inch) high compliance cone driver engineered to provide wide frequency response and wide dispersion for solid performance in paging and background music systems. The small size and broad-beam width of 170 degrees make it especially useful in rooms with low ceilings.

A&E SPECIFICATIONS

• The high compliance 4 inch driver shall be Lowell Model No. JR410. It shall be of the permanent magnet type having a paper cone with a treated cloth surround. It shall be capable of producing a uniform audible frequency response over the range of 67Hz-16kHz (±6dB) and 53Hz–20kHz (±8dB) with a dispersion angle of 170 degrees conical @2000Hz (–6dB). Average sensitivity shall measure 90.8dB (SPL at 1W/1M). Rated power rating shall be 15 watts RMS. The voice coil shall have a 1 in. diameter and shall operate in a magnetic field derived from a strontium ferrite (ceramic) magnet with 10 oz. nominal weight.Voice coil impedance shall be 8 ohms. The driver shall have a structurally reinforced stamped 20-gauge steel frame to maintain precise mechanical alignment and shall provide facilities for mounting a transformer. The driver shall have an overall diameter of 5.03 in. with four round holes equally spaced at 90 degrees on 4.69 in. diameter mounting bolt circle. Driver depth shall be 2.08 in. External metal parts shall be zinc-plated to resist rust and corrosion.
