About Eminence Speakers BETA-8A

The Beta-8A is recommended for professional audio mid-bass applications or as a woofer in vented enclosures. It can easily handle 450 watts and reproduce frequencies from 78 Hz to 4.5 kHz.

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. We coat each basket and all metal components with an epoxy-acrylic finish using our in-house e-coat process.
