Eminence ALPHA 2-8 overview

  • 1Description

Designed for tight fitting column and line array applications, the Eminence Alpha 2 American Standard Series Full Range Driver Set includes four 2" drivers, each with 0.64" copper voice coils and 2.7 oz ferrite magnets. With under spider venting and a flux source cap, these 8-Ohm drivers let the heat out while containing the magnetic flux, which is critical for multi-unit designs packed tightly together. The Alpha 2 is rated at 30W program power and features a wide frequency range of 200 Hz to 20 kHz.
