Overview

The Extron SI 28 two-way surface mount speaker features a ferrofluid-cooled, aluminum dome tweeter coupled to an Extron exclusive conical horn design for minimum phase shift and a flat response over the mid- and high-frequency ranges. Harsh tonal qualities due to cancellation in portions of the frequency range caused by phase shifting are all but eliminated with this exclusive conical horn design. A long-throw woofer with large magnets provides solid low-frequency response. This approach to crossover design assures a smooth transition from bass through midrange to the high frequencies, delivering optimum voice and music reproduction. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.
