An American-made speaker with a wide array of applications.

The American Standard Series Alpha-6CBMRA 6" Loudspeaker is recommended for professional audio mid-range applications in a sealed cabinet, or as a mid-bass in a vented satellite enclosure.

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. They can control the thickness of that coating to within 0.001"; critical when working with close tolerance transducer motor designs. Eminence then adds front and rear sealing gaskets on each model to accommodate front or rear loading.

There are 24 unique models available in the American Standard series. Each was designed for versatility in a range of applications. From 6.5-15" models with applications ranging from standard sub-woofers, two-way enclosures, and coaxials, to truncated line array models, monitor woofers, and high performance midranges setting records for output in car audio, no other loudspeaker line provides more choices, power handling, performance, and reliability for the price. As with the Professional series, each product includes a lot of Made in the USA pride, along with a Seven Year Warranty against manufacturer's defects*.
