Overview
This compact, full-range, 4" (127mm) speaker 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 speakers necessary to achieve total coverage in low-level distribution systems. The 10-watt, 8-ohm model (without transformer) offers a frequency response range of 150Hz - 17kHz, sensitivity of 94dB (at 1 watt, 1 meter) and a dispersion angle of 135° (-6dB, 2kHz octave band). The unit contains a 10 oz. (283g) ceramic magnet with a flux density of 10,500 gauss. This U.S.-made speaker 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 low profile position and enables torsion spring mounting found on many AtlasIED baffles.
