About this item

  • 1-1/8" aluminum diaphragm offers remarkable clarity without the typical harshness of metal domes
  • Exceptional efficiency at 92.5 ±3 dB from 1.5 kHz to 19 kHz and a smooth frequency response
  • Well-designed phase bridge to balance the response in the upper octave
  • Tuned rear chamber and high-quality Ferrofluid for excellent low-end response
  • Low-distortion motor system achieves a rare level of transparency


The Dayton Audio RST28A-4 1-1/8" aluminum dome Reference Series tweeter has remarkable clarity, low free air resonance, exceptional efficiency, and smooth frequency response, a combination seldom found in the industry at any price. This upgrade over the original RS28A-4 provides incredible performance at an amazing value.
