4" Standard Loudspeaker, UL Listed, 25/70.7V-4W Transformer
4" Standard Loudspeakers (UL Listed) 25/70.7V-4W Transformer
This compact, full-range, 4" (127mm) loudspeaker with a LT-72 transformer is equipped with a damped, high-compliance cone which provides excellent low frequency reproduction and smooth extended response. Model FC104 also offers a wide dispersion angle which reduces the number of loudspeakers necessary to achieve total coverage in low-level distribution systems. The 10-watt, 8-ohm model (without transformer) offers a frequency response range of 150 Hz to 17 kHz, sensitivity of 94dB (at 1 watt, 1 meter) and a dispersion angle of 135 (-6dB, 2 kHz octave band). The unit contains a 10 oz. (283g) ceramic magnet with a flux density of 10,500 gauss. This U.S.-made loudspeaker is available with six different factory-installed line matching transformers (see chart below) to meet a variety of project requirements. A dual-purpose bracket securely mounts the transformer in a lowprofile position and enables torsion spring mounting found on many Atlas Sound baffles.
