Dayton Audio Reference Series Aluminum Tweeter RS28A-4

The Reference Series tweeters' unique black anodized 1-1/8" aluminum diaphragms and state-of-the-art motor systems not only match the look and features of the Reference Series woofers, but also match the clean, detailed, and uncolored sound.

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

Dayton Audio Tweeter Highlights:

  • Tuned rear chamber for great low-end response
  • 1-1/8" Aluminum diaphragm offers amazing clarity without typical metal dome harshness
  • Low-distortion motor system achieves a rare level of transparency
  • Non-shielded version is perfect for high-performance audiophile speakers
  • Great replacement for the Dayton RS28A-4 1-1/8" Aluminum Dome Shielded Tweeter.3
