R2904/700000/5 Tweeter

The Revelator tweeter series consist of the revolutionary ring radiator design, which put an end to some of the design trade-offs in dome designs. The ring radiator still
offers unrivalled performance. 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 optimize airflow in the chambers.

Key features:

1" Ring Dome Diaphragm
Patented Symmetrical Drive (SD-2) motor
Non Resonant Alu Rear Chamber
Patented Phase Plug Design
Large Ring Neo Magnet f. High Output
Silver Anodized Mashined Alu Face Plate
