About This Product

Recommended for professional audio as a woofer in vented enclosures. The Omega Pro-18a is known as the best 18" for horn loading, scoops, and W bins.

Eminence Omega Pro-18a 18" Professional Series Replacement Speaker Features:

  • 1600 watts Program Power.
  • 18" Nominal Diameter.
  • 8 or 4 Ω
Application:
  • Woofer
  • Subwoofer
Suggested Enclosure:
  • Vented Box
  • Scoop Loading
  • Hord Loading
Each Eminence Professional model can be identified by its cast aluminum Eminence chassis that is lightweight and strong. Aluminum does not conduct the magnetic field out of the gap, thereby making the motor strength higher and the stray magnetic field lower. We coat each chassis and all metal components with an epoxy-acrylic finish using our in-house e-coat process. We can control the thickness of that coating to within 0.001"; critical when working with close tolerance transducer motor designs. We then add front and rear sealing gaskets on each model to accommodate front or rear loading.

There are 26 unique models available in the Eminence Professional series. Each was designed with a specific application in mind. From heavy-duty subwoofers, low distortion woofers, and super high-power woofers to lightweight neodymium transducers in truncated frames for line arrays, there is an Eminence Professional model for your application. Each product comes with a Seven Year Warranty against manufacturer's defects.
