Why choose this product?

The ARC Audio RS1.0 is a flagship 25mm silk-dome tweeter developed for high-resolution active systems. Its fine-woven silk diaphragm, high-strength neodymium motor, secondary bucking magnet and large copper shorting ring are engineered for smooth, detailed high-frequency reproduction with low inductance and distortion.

A cast-aluminium housing and tuned rear acoustic chamber lower the tweeter's resonance to 900 Hz, while integrated thermal-relief venting supports sustained performance. The removable outer ring adapts the RS1.0 between standard and ISO-style installations, and every pair is individually tested and hand-matched for acoustic balance.

Features

  • Matched pair of 25mm Reference Series tweeters
  • Fine-woven silk-dome diaphragm
  • High-strength neodymium motor with secondary bucking magnet
  • Large copper shorting ring reduces inductance and distortion
  • Cast-aluminium housing with tuned rear acoustic chamber
  • 900 Hz fundamental resonance
  • Integrated thermal-relief venting
  • Removable outer ring for standard or ISO-style mounting
  • Designed for 2-way or 3-way active systems
  • Individually tested and hand-matched pairs
