Thanks for the vote of confidence guys! I will just go ahead and start the transformation.
Boxozaxu, that is a great idea. That way I can use Erich's cnc cutout for the SEOS, which would look like a pain in the butt to cut out for a flush mount by hand. It also allows me to play around with using something different for the edges, give it a little flair. My baffle will be about 15% bigger, but If LTD02 says its ok, its ok! I am playing around with REW, though it likes to quit randomly on my Mac. In any case I will try to measure these guys when I am done to see what it does. I do have Audessy on my avr, which if I use it i am guessing it will attempt to flatten it out.
Will changing the placement of the ports on the baffle affect the response at all? I may have to move them down a few inches to avoid interior bracing.
