Reviews

Eminence Kappa Pro-12A 12" Cast Frame Driver
Eminence Kappa Pro-12A 12" Cast Frame Driver is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from The finest loudspeaker in it's category...I've built dozens of cabinets for front-of-house and stage monitor applications using the Kappa Pro Series over the past seven years with stellar success. Frequency response, fidelity, sensitivity, power-handling, reliability are all hallmarks of this line. Additional high quality features like high capacity binding posts and thick gaskets for front or rear cabinet mounting make this series my first choice. Eminence continues to be an industry leader providing loudspeakers and drivers for numerous major manufacturers and has branched out ever further with excellent choices in their lightweight neodimium speakers. Dozens of speakers to choose from in nearly every category and Made In The United States at very fair prices with excellent distribution. Parts Express is also one of the best at what they do!

Rated 4 out of 5 by from Best for specific applicationsMy main application was a horn loaded mid-bass from 80-300 Hz that was designed around this specific driver. Highest EBP in its price class, period. It performed as per the models - very, very, very LOUD - able to keep up with labhorns. I've played with this driver in small vented boxes, and it does well in about 1 cubic foot. Only downside is that it's top end isn't as nice as the Delta series, so it's more at home in a 3 way than a 2 way. Unless you're using a 2" on top. Teamed up with a couple of 6" and a 1" horn/driver, the box is still small enough - and cheap enough - to be thinking "line array".
