B&C 8PS21 8" Woofer
B&C 8PS21 8" Woofer is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Scan Speak on steroidsI call this driver "Scan Speak on steroids." It is a very clean and neutral driver with high sensitivity and decent xmax. Unlike many pro drivers, it doesn't have an ugly front gasket that needs to be hidden, although the octagonal shape adds some difficulty in flush mounting, and with a thick 11mm face plate it does need flush mounting. Provided you have a tweeter that can handle a crossover around 1.5 - 2k, this is an excellent driver for a 2 way covering upwards of 80 Hz.The casting is a little rough on the mounting face plate. That means if you have a nice neat flush mount arrangement, you will have to allow a small gap. The paint finish is also not as robust as it could be. Despite being well packaged, some of the paint had come off in transit. It isn't bad enough for me to be concerned, but I haven't had this problem with typical hifi drivers.I will be using this driver for some on-wall surrounds, but I'm impressed enough with the sound that I could be happy with this as a main speaker.

Rated 5 out of 5 by from Great Driver !I mated a pair of these to the Morel CAT378 (same sensitivity)and shifted the woofer forward 3/4" for better time alignment with 2kHz. 24 db LR crossover. These are by far my best sounding speakers to date. They do not go very deep so you will need a separate sub. My design was intended to allow me to use mine as Stage monitors or stand mount. I prefer the sound of these monitors using this driver over my churches older and long ago discontinued RCF ART300A's. I recently used this setup at and outdoor wedding and an coffee shop gig. Using this set up with a Sub using the B&C 12PS100 I'd say is the best small venue sound system I've heard to date. I credit this 8" driver for the very smooth midrange I've not had in other speakers and setups. The efficiency is less than most Pro stuff but the quality I got from this exceeds that of any pro stuff I've been able to use to date. I look forward to building more with these drivers.

Rated 5 out of 5 by from Excellent price/performance ratio.The 8PS21 is very nicely built, good fit and finish.I'm currently using the 8PS21 mated with the ME-10 and DE-10 and together they make a outstanding setup.They provide great clarity and detail/resolution without becoming fatiguing during long periods of listening time.Sensitivity is high but bass extension suffers a bit, but it's not bad if used with a subwoofer to take care of the low end.Test results can be seen at Zaphaudio.com

Rated 5 out of 5 by from Amazing fidelity and power handlingThese are the drivers used in the QSC I H28 speakers. I bought a pair three months ago and have been amazed and delighted ever since. They handle 200 watts at 8 ohms without a hint of distortion. In conjunction with the compression drivers they make a fantastic combination. Detailed, flat, nuanced, smooth, clear, LOUD! In this price range, it is unlikely you could get a better woofer.
