Power rating shall be 15 watts RMS. The voice coil shall have a 1-in. dia. and shall operate in a magnetic field derived from a strontium ferrite ceramic magnet having a nominal weight of 10 oz. Voice coil impedance shall be 8ohms. The driver shall have a round, structurally reinforced stamped 20-ga. steel frame with 8.062" overall diameter and eight obround holes equally spaced at 45 degrees on a 7.625" dia. mounting bolt circle. Overall depth shall not exceed 2.84". External metal parts shall be zinc-plated to resist rust and corrosion. The mounted transformer shall be 70/25V dual voltage with selectable taps at .25, .5, 1, 2, and 5W. The assembly shall be capable of producing a uniform audible frequency response over the range of 51Hz-11.6kHz ( 6dB), 50Hz- 20kHz ( 6.4dB) with dispersion angle of 95 degrees conical @2000Hz (-6dB). Average sensitivity shall measure 97.9dB (SPL at 1W/1M).

BACKGROUND MUSIC AND PAGING 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. 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.

High performance 8-inch 20W coaxial speaker with post mounted, coaxially positioned tweeter for improved performance over a traditional full-range (dual cone) speaker. 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.

Features

• Description:  8 in. 20W coaxial speaker with high frequency driver with first order high pass filter to protect it from harmful bass energy. Provides optimum low end performance when teamed with Lowell's DX Series acoustic backbox (1-3 cu.ft.) or protective backbox with acoustic fiberglass batting.
• Frame:  20-gauge stamped steel with zinc-plated finish.
• Power Rating:  20W RMS
• Mounting Depth:  3.20 in.
• Mounting Bolt Circle:  7.625 in.
• Dispersion Angle:  80 degrees conical
• Frequency Response:  57Hz-14kHz (±6dB) and 44Hz-20kHz (±7.6dB)
• Average Sensitivity:  97.0dB
