About This Product

Designed for high power bass in sound reinforcement systems, bass guitar combos, club music systems and stage monitors. Eminence LF models are specially designed with extended Xmax to deliver more bass than standard models and provide "a true woofer" for three-way applications.

The American Standard Series Eminence Delta-15LFA is a low frequency woofer for pro audio as a midbass or floor monitor in a sealed enclosure. Also suitable as a woofer in vented bass guitar or PA enclosures.

Eminence Delta-15LFA American Standard Series 15" Replacement Speaker Features:

  • 1,000 w Program Power.
  • 15" Nominal Diameter.
  • 8 or 4 Ω.
Application:
  • Midbass
  • Woofer
  • Subwoofer
  • Bass Guitar
Suggested Enclosure:
  • Sealed Box
  • Vented Box
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 comes with a Seven Year Warranty against manufacturer’s defects.
