Description
6-1/2" Sealed-Back Midrange Speaker, 8 Ohm, 100 Watt
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.
Features:
- Sealed back speaker basket for use in multi-way cabinets with sub-enclosures.
- Perfect for use as a high output car audio door speaker
- Features the Eminence Alpha family sound
