ALPHA 4
Perfectly suited for line array, car doors or 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.
