Eminence Delta 12LFA

Eminence Delta 12LFA - 12" 500W 8 Ohm

Each Eminence American Standard model can be identified by its economical Stamped Steel chassis. Although more affordable than cast aluminium, these frames provide an excellent and versatile chassis. Eminence coat each basket and all metal components with an epoxy-acrylic finish using their in-house e-coat process. The thickness of that coating is controlled to within 0.001"; critical when working with close tolerance transducer motor designs. They then add 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 their Professional series, each product includes a lot of Made in the USA pride.

Application Notes: LF Models are designed with extended Xmax to deliver more bass than standard models and provide a "true woofer" for three way applications.

Recommended for professional audio mid-bass or floor monitor applications in a sealed enclosure. Also suitable as a woofer in vented, bass guitar or PA enclosures.
