XT/DX
13 Tweeter
Type Number: XT25SC90-04
Features:
The goal for this tweeter series was to create a transducer that
has a frequency response that is flat to above 20K, and where
the distortion is far lower than normal and more friendly to the
ear. The tweeters represent a unique approach to tweeter design
that has resulted in unrivaled performance, as well as in several
patents (Dual Ring Radiator diaphragm, wave-guide center plug).
Driver Highlights: Dual Ring Radiator diaphragm (Patent), Wave-
guide center plug (Patent), copper-clad aluwire
