Product details

SB Acoustics SB20FRPC30-8 8” Full-range Paper Cone Driver

Using a cone proprietary paper blend cone made in house this woofer delivers good midd/bass response. Which is extended by the use of a optimized “whizzer” cone. This is supplemented by the use of a phase cone to better radiate the high frequency output. The paper blend cone is made in-house to insure quality control. This makes this a good “bang for the buck” full range driver.

Amazing speakers. Easy to drive, very good clarity, reasonable bass extension.

I don't have enough experience with other full range drivers to compare it to. But it's a great sounding driver for the price. I have it mounted in a 70l ported enclosure, and while the low bass is lacking. With some wide-band equalization (no crossover used) the sound is enjoyable and natural.

Hard to beat with that price. I installed them in wall with ported enclosure 120*63*11 for home cinema and I can't believe how quality and balanced sound they produce.

Really good full range driver used as a surround back channel. Still experimenting with box size but nice full sound. At the price I have no complaints.

The best 8-inch full range driver I have ever had so far! (and I had quite a few already)

Voor de prijs is het een goede driver, maar ik had er meer van verwacht.

Haven't had the opportunity to really test the driver yet, but ordering and delivery was very good. I had a request about my order and it was dealt with very efficiently. Highly recommend this shop.
