Eminence Alpha-6CBMRA 6-1/2" Ferrite Sealed Back Midrange Speaker Driver

Based on the ever-popular Alpha 6 series, Eminence's 6-1/2" sealed-back Alpha-6CBMRA midrange speaker is built with a closed basket design to prevent interference from other drivers in a speaker cabinet without the need for a separate sub-enclosure. 

The Alpha-6CBMRA features the standard paper cone, cloth accordion surround, and solid composition paper dust cap of the other Alpha drivers for a consistent family sound. Use this midrange in professional 3-way live sound cabinets, as a high output car audio door speaker, or as a midrange in a bass guitar speaker.
