Overview

Dayton Audio RS28F-4 1-1/8" Silk Dome Tweeter

Dayton Audio's Reference Series tweeters are designed to complement the RS woofers. The RS28F-4 incorporates an optimized silk diaphragm that combines low mass, superb damping, and a carefully calculated dome profile. A tuned rear chamber, supported by a rugged diaphragm assembly, enables crossover possibilities in ranges as low as 1,000~1,100 Hz (with the appropriate filter). This unique 1-1/8" silk dome and a state-of-the-art Ferrofluid cooled motor system employs copper shorting rings to ensure that high frequency content is reproduced as transparently as possible, assuring studio-quality performance. RS28F-4 tweeters not only match the look and features of the RS woofers but also the clean, detailed, and uncolored sound that characterizes the entire series.
