What Is A Silk Dome Tweeter?

Silk used in tweeters has several benefits offering great characteristics as a tweeter diaphragm. Being a natural fibre it is very light with high quality damping abilities. With silk being a softer material compared to the traditional hard dome tweeters, they tend not to show as much high frequency extension. Silk dome tweeters are chosen by many audiophiles because of smoother high frequencies and overall balance.
