Eminence ALPHA 3-8 3" Full-Range Pro / Car Audio Speaker 60 Watts 8-Ohm

The Eminence Alpha 3-8 is a 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" driver utilizes an 8.3 oz ferrite magnet in conjunction with an internal neodymium bucking magnet for increased sensitivity and extends the response to 20kHz. The highly pressed cone sandwiches paper with a layer of water-resistant polypropylene for increased stiffness and lower distortion.
