Динамик ВЧ SCANSPEAK R2904/700009. Инструкция на английском языке

TWEETER                                                   R2904/700009
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.
