1" Dual Concentric Diaphragm with Ring Radiator Tweeter
The smaller-sized features a patented dual concentric textile diaphragm and a unique waveguide center plug that provide an excellent on- and off-axis response.
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 XT tweeters are acclaimed for their very natural sound with an extremely smooth frequency response extending well beyond the human hearing range.
