Eminence ALPHA10A 10In Rawframe Speaker
Eminence Alpha-10A 10-Inch Rawframe Speaker
The Alpha-10A is recommended for professional audio mid-bass applications in a small sealed cabinet. Each Eminence American Standard model can be identified by its economical Stamped Steel chassis. Although more affordable than cast aluminum, these frames provide an excellent and versatile chassis. Eminence coats each basket and all metal components with an epoxy-acrylic finish using their in-house e-coat process.
