Excellent general purpose tweeter

This is an excellent tweeter at a very affordable price point. It is a metal dome but does not have any harshness associated with metal domes. I have done swept-sine harmonic distortion measurements too, and the distortion profile is astonishingly low. It can be crossed over at 1.8K or 2K fourth order. With tweeters like this one and the related model, the SB26ADC, it is hard to justify why one needs to use anything more expensive.
