high-quality commercial, in dus tri al, and in sti tu tion al ap plica tions.
General Description
Model C803A. High-quality, 16 Watt model C803A utilizes a post-mounted
tweeter which adds strength to the assembly and provides an attractive
ap pear ance. This coaxial loud speak er features a 70Hz–15.5kHz, (±5dB)
frequency response and a broad, uniform dispersion pattern of 120˚.
Such provisions allow for highly in tel ligible sound reproduction and better
C803A
distribution for high-quality sound systems. The C803A combines a full-size 8"
(203mm) diameter low-frequen cy re producer and a 3" (76mm) high-frequency
re pro ducer. The two sections are coupled via a built-in crossover network.
The woofer has a 10oz. (260g) ceramic magnet; the tweeter has a 2.35oz.
(67g) ceramic magnet and the unit has a peak sensitivity of 98dB (at 1W/1M).
The loudspeaker is available with six different factory-in stalled line-matching trans form ers to meet a variety of project re quire ments. Model C803A
mounts a wide variety of Atlas Sound baffles and enclosures, with the
optimum sealed enclosure size being .36 ft
