SB Acoustics, SB20FRPC30-8

Product Description

SB Acoustics, SB20FRPC30-8, 8″ Paper Cone  Wide/Full Range 8 Ohm Woofer

Using a proprietary paper blend cone made in-house this woofer delivers good mid/bass response, extended by the use of an 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 ensure quality control. This makes this a good “bang for the buck” full-range driver.
