Description
JR410: Driver
Commercial industry standard 4 inch (EIA 5
inch) high compliance cone driver is 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.
Perfect for background music and paging

- Frame: 20-gauge stamped steel, zinc-plated.
- Mounting Depth: 2.08 in.
- Mounting Bolt Circle: 4.69 in.
- Dispersion Angle: 170 degrees conical
- Frequency Response: 67Hz-16kHz (±6dB) and 53Hz-20kHz (±8dB)
- Average Sensitivity: 90.8dB
- Made in U.S.A. with global components
- Meets or exceeds industry standards
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.
