Product Details

Eminence Beta-10CBMRA 10" Sealed Back Midrange Speaker

Look no further for a driver for use in large format, multi-way live sound loudspeakers. The Beta-10CBMA sealed-back 10" midrange speaker from Eminence provides extremely high midrange output from 300 to 4,000 Hz. A 200W RMS, 400W program power rating allows it to be used in large venue, concert-level applications.

Most midrange speakers require a separate enclosure to protect them from interacting with the air modulated by larger woofers and subwoofers when loaded into the same cabinet. The sealed steel basket built onto the Beta-10CBMA provides a physical barrier from other drivers, for protection and lower distortion. 

High SPL car audio system builders will love the moisture protection offered by the sealed back design in addition to the extremely high 99 dB sensitivity that requires less amplification than most other pro audio midrange speakers. A paper cone and cloth accordion surround are employed for a natural, classic sound. Proudly made in the U.S.A.
