Description
SCAN SPEAK Hochtöner D2905/990000 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:
. Excellent Sound Reproduction
. Patented Symmetrical Drive (SD-2) motor
. Large Wave Guide Front
. 1" Textile Dome Diaphragm
. Wide Surround Textile Diaphragm
. Black Anodized Mashined Alu Face Plate
