Tweeters are sealed speakers, so the roll off depends on the size of the rear chamber.
Many brands have developed tweeters with rear chambers to decrease Fs[Hz] and allow lower crossover point, which is really interesting.
We have deeply analyzed how the rear chamber works, and how it affects the acoustic performances, especially the distortion.
Our .Koupled chambers solution uses inner resonator, which makes the tweeter working as a speaker in a vented enclosure in low frequency.
This innovation increase the tweeter sensitivity in the midrange and limit the dome excursion.
As a consequence, the distortion is significantly reduced in this sacred band, where the human ear is very sensitive.
The measurement below compare our Twt28_vMS with and without Koupled chamber.
The measurement has been done at the maximal power handling.
- Red : Koupled chambers
- Green : No coupled chambers
