Atlas Sound SD72WV 8" Ceiling Speaker with Volume Control
The speaker used in the SD72WV is the next generation of Atlas high performance cone loudspeakers, very similar to the preceding C-Series speakers. The similarity in the sonic qualities ensures that contractors and designers who have worked with the Atlas Sound C-Series in the past will know exactly what to expect when they use the SD72WV. Model SD72WV is a 25 watt 8" (205 mm) loudspeaker with a 10 oz. (260 g) ceramic magnet. It includes a curvelinear, treated paper cone for lower harmonic distortion. The loudspeaker is also equipped with a full 1" diameter copper voice coil with a black anodized aluminum former for better power dissipation. Model SD72WV operates within a frequency response range of 45 Hz-19 kHz (nominal) with a sensitivity of 97 dB and a dispersion angle of 105°. Package includes factory installed 25/70.7V line matching transformer with tap selections ranging from .25 to 5 watts.
The SD72WV includes a factory installed CRS baffle with concealed loudspeaker mounting studs and includes screw mount hardware. The SD72WV baffle features standard mounting holes to accommodate the majority of Atlas Sound 8" tile bridges, mounting rings and enclosures.
When specifying mounting hardware be advised that the dimensions of the SD72WV baffle match the Atlas Sound Model 62-8. The baffle finish is white powder coat epoxy. The baffle mounted volume control has a 5 watt audio rating and is factory wired to the voice coil. Units are shipped assembled, ready for installation.
Specifications: Depth: 2-7/8" (7.30 cm) Diameter: 8-1/8" (20.64 cm) Shipping weight: 5.63 lbs. (2.55 kg) Frequency response: 100 Hz-10 kHz (±1.5 dB) Power taps: .25, .5, 1, 2, 5 Speaker type: Treated paper Dispersion: 105° (2 kHz Octave Band, -6 dB Points) Sensitivity: 97 dB Average UL listed/standard: 1480, 2043.
Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.
