Data Sheet

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” 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.
