I do not hear at the super tweeter level anymore.
Interestingly enough recently a longtime friend who has forgotten
more than I will ever know about sound told me
that even I would benefit from high frequency tweeters.
Why, how I asked? I do not know if he even knew the real
reason why but he did believe it. Thanks for bringing this up
again as now I will experiment with tweeters that play beyond
my measured frequency hearing. If sub woofers can make a system
improve overall beyond the few additional abs they add then why
not the same on the other end???
