TWEETER R2904/700005
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
- Black Anodized Machined Alu Face Plate
