Description
12" Neodymium High Output Driver, 8 Ohm, 400 Watt
The Eminence Kappalite 3012HO 12" speaker is a high power driver for pro audio or MI applications. Cast aluminum basket, polyimide VC former, and treated paper cone with cloth double half-roll edge. The optimized neodymium motor greatly reduces weight while still delivering high efficiency with low distortion. Great for 2-way systems including floor monitors, and as the mid component in large multi-way PA systems. Excellent results when used in horn-loaded mid designs.
