Dayton Audio RST28A‑4 1‑1/8" Aluminum Dome Tweeter — Precision That Cuts Through
This isn’t a tweeter that “adds sparkle.” The RST28A‑4 delivers transparent, detailed highs without the brittle edge metal domes usually bring. Its 1‑1/8" aluminum diaphragm gives remarkable clarity while staying smooth and natural across the upper octave.
Why it matters
- High efficiency at 92.5 ±3 dB from 1.5 kHz to 19 kHz for effortless output and cleaner system gain structure.
- Low distortion motor system for rare transparency and accurate imaging.
- Well‑designed phase bridge balances the upper frequencies for a cohesive, non‑fatiguing top end.
- Tuned rear chamber and premium ferrofluid improve low‑end extension and thermal stability under load.
- Robust build with an aluminum dome and precision engineering that outperforms its price class.
The result You get crisp, airy highs that reveal detail without harshness, a smooth frequency response that integrates with midranges, and efficiency that keeps your system sounding alive at lower power. The RST28A‑4 is the upgrade that turns a good system into a revealing, musical system.
Green Bee Solutions brings you the RST28A‑4 — the tweeter that gives your system pro‑level clarity without the edge.
