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.

Eminence then coats each chassis and all metal components with an epoxy-acrylic finish using its in-house, e-coating process. They then control the thickness of that coating to within 0.001”; critical when working with close tolerance transducer motor designs, then add front and rear sealing gaskets on each model to accommodate front or rear loading.

Each product comes with a Seven Year Warranty against manufacturer’s defects.
