Product Description

The Dayton RS28A-4 Reference Series tweeter is designed to be an excellent match for the Dayton Reference Series woofers. The tweeter's unique black anodized 1-1/8" aluminum diaphragm and state-of-the-art motor system not only matches the look and features of the RS woofers, but also matches the clean, detailed, and uncolored sound. A cast aluminum faceplate, protective mesh grill, tuned rear chamber, and several distortion-reducing paths in the motor system are just a few of the features that allow this tweeter to outperform many expensive audiophile high-frequency transducers.
