Yes we really have looked at as many of the issues we feel are relevant to listening to speakers in real rooms.  If you have not had a chance to watch the Floyd Toole seminar I posted have a look as it really does have a lot of great information - under Speaker Design.

You have a day off so there's no excuse not to watch it. .

James:
I watched the F. Toole lecture , too bad it only lasted an hour, he was just getting warmed up. : )
I also follow these other characters, in no particular order , S. Olive, E. Geddes, A. jones, P. Barton etc.

It was the "Home Theater Geeks 263" interview with Andrew Jones that prompted my tweeter query.
Andrew found a problem in his prototype tweeter and corrected it his latest production ELAC speakers.
He noticed his prototype had a 3db dip in the measured response at 15KHz.
 
Very similar to the latest NRC measurements of your  Mini A's.

Andrews fix was to remove all irregularities around the dome ... Shawn

Hi Shawn

Yes I was aware of that but as I have said before you are not listening to that measurement as it is one point in space with a microphone. You are listening to the Sound Power and that small deviation is irrelevant. Thats not to say you do not try to improve things.  We have been using a new tweeter now for a while in the T Series and it does reduce some of the effects that were measured in the older tweeter
