      Dayton Audio RST28A-4 1-1/8" Reference Series Aluminum Dome Tweeter 4 Ohm


      The Dayton Audio RST28A-4 aluminum dome Reference Series tweeter offers exceptional efficiency from 1,500 Hz to 20,000 Hz with smooth and well controlled frequency response. This tweeter's unique black anodized 1-1/8" aluminum diaphragm and state-of-the-art motor system not only match the look and features of Dayton Audio's Reference Series woofers and midranges, but also the clean, detailed, and uncolored sound you have come to expect. A specialized damped rear chamber, well-designed phase bridge, rigid mesh grill, and several distortion-reducing paths in the motor are just a few of the features that allow these tweeters to outperform some the most expensive audiophile high-frequency transducers.
