Data Sheet AS07808AS-R PUI Audios Copperhead Series was conceived to create a family sound across three different speaker sizes: 36mm, 53mm, and 78mm square. Specialized alloy cones are paired with optimized motors to achieve superior frequency response and output, with minimized harmonic distortion. The eight ohm, 78mm square frame AS07808AS-R features a rubber surround, for water and dust resistance, and a shielded double-stacked motor to protect sensitive components and for high sensitivity. Features: Coated alloy cone for extended frequency response to 40 kHz 82 dB output at 1m (102 dB output at 10cm) High-energy, double-stacked magnetic motor Large 20mm diameter voice coil for high power handling Easy-to-mount square frame Specifications Parameters Values Units Rated Input Power 15 Watts Max Input Power 30 Watts Impedance 8 15% Ohms Sensitivity (SPL 1W/1m) Avg. at 2, 4, 8, and 16 kHz 82 3 dB Resonant Frequency (in free air) 12020% Hz Frequency Range (-20 dB) 60 ~ 40,000 Hz Frame Material Stamped Steel - Magnet Material NdFeB - Weight 560 Grams PUI Audio, Inc., 3541 Stop Eight Road, Dayton, OH 45414 Tel: (937) 415-5901 Fax: (937) 415-5925 This document contains data proprietary to PUI Audio Inc.
