Description
SCAN SPEAK Hochtöner R2904/700000 Ringradiator REVELATORThe 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.
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
