Eminence Alpha 4-8 - 4" 55W 8 Ohm

Perfectly suited for line arrays, car doors and side panels, and other tight fitting applications, the Alpha 4 is a very versatile 110 watt driver that can be used full range, as a midbass, or as a midrange. They can be stacked by themselves in a column for vocal applications, or in conjunction with a tweeter and a sub for compact, high performance PA or MI applications.
