The Professional Series LAB12C 12" Loudspeaker is recommended for vented, sealed, and horn loaded, professional audio enclosures as a subwoofer. It's also great as an automotive sub.
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 coats each chassis 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 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, along with a Seven Year Warranty against manufacturers defects*.
