XT/DX 0.75" Tweeter

Vifa
Type Number:XT19TD00-04

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: 3/4" tweeter, Dual Ring Radiator diaphragm (Patent), Wave-guide center plug (Patent), copper-clad aluwire
