Product Description

The Dayton Audio PM220-8 8" midbass driver is based on the same platform as the acclaimed Point Source full-range drivers, but designed for esoteric high-performance applications requiring an extremely wide-bandwidth midrange or midbass driver. The PM220-8 model provides the ultimate in high-efficiency performance in a variety of system designs, including vented, transmission line, folded horn, or open baffle applications.

The PM Series mid-bass drivers feature ultra-linear Klippel-optimized neodymium motors with copper cap and shorting ring for low distortion, and lightweight, low-loss Kevlar-reinforced paper cones for exceptional detail and high efficiency. The wide bandwidth and extended upper range of these drivers makes them the perfect complement to ribbon and planar-magnetic tweeters.
