Eminence Alpha 3-32 3" American Standard Series Speaker, 32 Ohm

The Eminence Alpha 3-32 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 70 watts, this 3" driver utilizes an 8.3 oz ferrite magnet 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.

Applications: Full Range Line Array | Pro Audio | Car Audio | Bass Guitar | Soundbars | Satellite System

Box Type: Sealed | Vented

The Alpha 3-32 from Eminence Loudspeakers will allow you to pack big performance into small spaces. Perfectly suited for portable speaker systems, column, and line array applications this is a truly versatile full range driver.
