OX 0.75" Tweeter
Vifa
Type Number:OX20SC00-04

Features

In this tweeter design, the audio engineers have reinvented the traditional dome tweeter yet again. Based on the knowledge obtained from work on the Vifa XT series, the R&D team has combined a traditional dome design with the large surround of the XT. This results in a tweeter that has a very good dispersion and low distortion due to the improved control of the diaphragm.

Driver Highlights: Dome tweeter; fabric diaphragm; high sensitivity; a back chamber on the neodymium driver that lowers Fs for improved flexibility and performance when combined in a design with small woofers; improved airflow for lower compression, which improves the dynamic range of the tweeter; lower Qts for reduced distortion; improved cooling due to internal ventilation
