Eminence Speaker ALPHA38 3 in. Full-Range Driver - 8 ohm

(SINGLE PACKED) The Eminence Alpha 3-8 is a truly versatile compact full-range driver perfectly suited for tight fitting pro audio line array and column array applications. With a program power rating of 60 watts, this 3-in driver utilizes an 8.3 oz ferrite magnet in conjunction with an internal neodymium bucking magnet for increased sensitivity and extends the response out to 20kHz. The highly pressed cone sandwiches paper with a layer of water-resistant polypropylene for increased stiffness and lower distortion. * Nominal Basket Diameter 3-in, 76 mm * Nominal Impedance* 8 Ohms * Program Power 60 W; Watts 30 W * Resonance 118 Hz * Usable Frequency Range 150 Hz - 20 kHz * Sensitivity* 88.6 dB * Magnet Weight 8 oz. * Gap Height 0.1-in, 2.5 mm * Voice Coil Diameter 0.787-in, 20 mm * Resonant Frequency (fs) 118 Hz * DC Resistance (Re) 5.12 ohms * Coil Inductance (Le) 0.11m H * Mechanical Q (Qms) 7.94 * Electromagnetic Q (Qes) 0.53 * Total Q (Qts) 0.5 * Compliance Equivalent Volume (Vas) 0.95 liters / 0.03 cu.ft. * Peak Diaphragm Displacement Volume (Vd) 6.9 cc * Mechanical Compliance of Suspension (Cms) 0.84 mm/N * BL Product (BL) 3.93 T-M * Diaphragm Mass Inc.
