Marlboro, yes I have read Dr. Griffins paper. I think sometimes I have read it a few to many times. I might not have made it clear of what I was thinking. I don't want to do an array of the BG 6es I was trying to describe the idea of the tweeter in front of the mid/bass. I did some more looking around the web and found this:http://www.bgcorp.com/radia.php
This idea but using a Newform or BG Planer or an array of bg neo 3 but way closer together then the link above. I was looking for information on the affect of the tweeter in front of the mid/bass. I would guess there is going to be a frequency output of the mid/bass to width of tweeter that should not be exceeded.
