4" High-Compliance Loudspeaker with Transformer
FC104 Series
Applications
Utilize Atlas Sound 4" high-compliance loudspeaker Model FC104 for
voice trans mis sion, music and signal re pro duc tion in commercial, in dus tri-
al and in sti tu tion al applications of all kinds, especially those where a high
performance loud speak er is required and wide dispersion is demanded.
General Description
This compact, full-range, 4" (127 mm) loudspeaker is equipped with a
damped, high-compliance cone which provides excellent low fre quen cy
re pro duc tion and smooth extended response. Model FC104 also offers
a wide dispersion angle which reduces the number of loudspeakers
nec es sary to achieve total cov er age in low-level dis tri bu tion systems.
The 10 watt, 8Ω model (w/o transformer) offers a frequency response
range of 150 Hz – 17 kHz, sensitivity of 94 dB (1 W / 1 M) and a disper-
sion angle of 135° (-6 dB, 2 kHz octave band). The unit contains a 10 oz
(283 g) ce ram ic magnet with a flux density of 10,500 gauss. Loudspeaker
is available with three different factory installed line matching transform-
ers to meet a variety of project requirements. A dual-purpose bracket
securely mounts the transformer in a low profile position and enables
torsion spring mounting found on many Atlas Sound baffles. (Bracket
not included on base model FC104.) For additional information on Atlas
Sound Transformer models, refer to #SL1-1369.
