I don't think a port would make a difference. what happens is the two drivers/ports fire together and you get a sum of the output from the two devices as one wave.

Micah, the walls used have to be opposite each other so that the output of the sub(or subs)at one wall reaches the other sub or subs at a point where they're of opposite polarity and cancel some of the modes. So, if neither both side mid-wall areas nor both front and back mid-walls were available to you, then Dr. Toole's suggested setup(again, note he said just by a "narrow margin")couldn't be implemented. The four corner arrangement would appear to be best available option. The two front corner and back mid-wall co-location plan you suggest certainly shouldn't be bad, but there's no info available as to how it would compare with the four corners setup.

Enjoy the music, not the equipment.

Ah, I see. Yeah my fiancee has her desk in the back, right hand corner, so 4 corners wouldn't work in here either. Not to worry though, as I was only asking out of curiosity. I don't ever see me having 4 EP800's in here. Still, a guy can dream. ![smile \:\)](/boards/images/graemlins/default/smile.gif)

Aren't you still going to try an infinite baffle sub sometime?

It's still on the back burner... but once Axiom sent me the new EP800 with the new sub amp in it, the back burner got turned down to LOW!!! The performance I get now is really so satisfying that my eagerness to experiment with a lot of those other sub idea's died down quite a bit. It's sort of like a teenage virgin thinking about sex 24/7 because he doesn't have it, so sex consumes his every thought... Then 5 years later the same kid is working in porn, shooting 3 or 4 movies a day, constantly bombarded with sex, sex, sex all day long... I'm not saying he gets tired of sex, I'm just saying it's definately not going to be the ONLY thing on his mind anymore! ![wink ;\)](/boards/images/graemlins/default/wink.gif)
