B&C 8PE21 8" Midrange Speaker
High efficiency and articulate response are trademarks of the B&C Speakers 8" cone midrange driver, which is a good choice for three and four way systems. The 8PE21 performs well in direct radiator applications, or with front horn loading from 400 Hz up to 3 kHz. A copper ring in the 8PE21's magnetic circuit reduces distortion and extends high frequency response.
