Eminence Delta 15LF - 15" 500W 8 Ohm
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 coat each basket and all metal components with an epoxy-acrylic finish using an 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. Front and rear sealing gaskets are then fitted to each model to accommodate front or rear loading.
There are 24 unique models available in Eminence's 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.
The Eminence Delta 15LF is recommended for professional audio as a mid-bass or floor monitor in a sealed enclosure. Also suitable as a woofer in vented, bass guitar or PA enclosures.
