Vifa XT25BG-60-04 Tweeter

XT25BG60-04

25mm Ring Radiator, dual magnet, 4Ω.

Vifa version of:  Scanspeak R2604/833000

This 25 mm dual ring radiator with centre phase plug has a low distortion response curve that extends effortlessly to above 40kHz. A double magnet system with tuned rear chamber yields an exceptionally low resonant frequency of just 589 Hz, which is a long way below the recommended crossover frequency - this tweeter is easy to use. The specially profiled 104mm diameter faceplate features recessed mounting holes for minimal reflection.
