Product Details

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.

B&C 8PE21 8" Midrange Speaker
B&C 8PE21 8" Midrange Speaker is rated 4.5 out of 5 by 6.
Rated 5 out of 5 by from ownerI think that the B & C speaker is one of the best for it's size they are the only ones I use I own a total of 22 speakers I have built 10 line array boxes with dual eight and a 1.4 waveguide ", and 4 with a Horn, eight, and 15" in each box,

Rated 5 out of 5 by from Outstanding driverI paired these with an Altec 515 bass drivers & Selenium 1" throat exponential horns/drivers in 70's vintage (large) bass reflex cabinets. All drivers have sensitivity so drive well at low powers. Crossed over at 500 & 1500Hz. Sound and presence are outstanding. B&C quality is excellent. Cloth roll surrounds will last as long as those on the Altecs (60-80 yrs?). Cone Mass/force is as high as will be found in this freq range ensuring fast, seemingly effortless response.

Rated 5 out of 5 by from Compares with the best for a fraction of the cost!I've just completed a pair of Dallas II horns loaded with these drivers. I'm crossing them on the low end at 80hz with a 48db/octave roll-off. On the high end, I'm rolling them off at 1K, 24db/octave.At low volume, they purr right along as one would expect. After a few minutes of break-in I cranked the volume control--it was like opening a soundproof door and walking into a party! They carried their load with stunning realism, acting as if they had endured no stress what-so-ever.Smooth, sweet, and powerful, that's how I'd describe the sound.I can't see myself using any other driver for this portion of the audio spectrum. Wow!

Rated 4 out of 5 by from Used for HT Center ChannelI am using this driver as a center channel in my HT system. No tweeter incorporated yet, but the voices are reproduced very accurately. The enclosure is a short transmission line tuned to ~70Hz, for use as a "small" (bass limited) speaker. The efficiency is very high and should be considered when matching with other speakers. Was concerned about the small Xmax, but haven't had any problems thus far. Unit is beefy and of the highest quality. High frequency roll of is very natural sounding.

Rated 4 out of 5 by from One of the best.This is the best pro sound 8" woofer that Parts Express carries. These work very well as a direct radiator from 200Hz to 5KHz for stage monitors. However, they excel in horn loaded applications. We have them in 100Hz exponential horns to cover 120Hz to 1.5KHz in a 3-way installation. In the horns they are 106dB sensitive with 1 watt. They mate up very well with the B&C DE-250 compression driver. Below 120Hz we run our horn loaded Eminence Definimax bass horns. Couldn't ask for better sound. Would have ranked it higher in value, but they are expensive. I guess you do get what you pay for. You can't go wrong with this 8" woofer.

Rated 4 out of 5 by from finally a professional 8 inch midrangeB&C was thinking outside the box on this one. I designed and built a straight horn using this driver, the response goes out to 3kHz! The magnetic force vs cone weight is very high allowing excellent horn mid freqs.

B&C 8PE21 8" Midrange Speaker

B&C's website claims this driver has an Xmax of 3.5 mm. Your website claims an Xmax of 1 mm. Which is correct?!? This is a huge difference in max performance and max SPL.

Asked by: carpenter
The Xmax on this driver is 3.5mm, I will have the site updated.

Does this speaker come in 4 ohms? Tryed an 8 ohm in my monitor and it smoked and fryed on stage.

Asked by: GasMan
Having a 4ohm over an 8ohm will not do anything to keep a driver from burning up. It sounds like you gave the speaker too much power and/or bass frequencies that lie outside of the designed range. If anything, a 4ohm will draw more current and burn up even quicker.This, and other 8 inch pro drivers are designed for mid bass applications, make sure you have a high-pass filter installed to keep the lower octaves away from the driver.

how many speakers come in a packege that cost 110 dollars ?

Asked by: elmellobm7
This product is sold individually, not in pairs. B&C is a very highly regarded Italian manufacturer of speaker components, generally considered to be among the upper echelon in the industry.
