Description

26mm Dome Tweeter 4ohm, Large Ring Neo, Black Faceplate

The Revelator Tweeters' large roll surround technology represents a breakthrough in overall performance, with outstanding off-axis response, high output capability and low resonance frequency. Additional enhancements have been made to reduce distortion and power compression, such as large neodymium magnet systems for high sensitivity, and a careful design to optimise airflow in the chambers.

Features

  • 1" Coated Textile Diaphragm
  • Large Roll Surround f. Wide Dispersion
  • Patented Symmetrical Drive (SD-2) motor
  • Large Ring Neo Magnet f. High Output
  • Non Resonant Alu Rear Chamber
  • Black Anodised Machined Alu Face Plate
