Lighter weight version of the Delta Pro 12.
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. Each chassis and all metal components are coated with an epoxy-acrylic finish using an in-house e-coat process. The thickness of that coating can be controlled to within 0.001"; critical when working with close tolerance transducer motor designs. Then front and rear sealing gaskets are added on each model to accommodate front or rear loading.
There are 26 unique models available in the 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 includes a lot of Made in the USA pride.
