Can someone explain how the tweeter configuration in Tekton speakers works? When I put my ear close to each tweeter it's hard to tell whether or not there is sound emanating from that particular driver as they are so close to the other tweeters. It seems that if one of those tweeters (or an associated crossover component) fails, it might not be obvious. Or, is it like the old Christmas tree lights where if one failed they all went dark? When a driver in a conventional speaker fails it is obvious because such a large portion of the sound spectrum is lost. Not so with Tektons. Please explain. Thanks.
