why does my strange Magnepan placement work?...or why shouldnt it?
....i was really struggling with the placement of the speaker panels in my 2 channel music room, seemed like i just couldnt get them far enough away from the walls and they almost wanted to sit in the center of the room....even if i had them over 8feet away from the back wall, i just didn't have the room width to get them any distance from the side walls; and the side walls were somehow kinda destroying a good 'sound stage' stereo image between the speakers....not that it was 'bad', it just wasnt 'great', or as great as i thought it could be....and i was continuously tweaking their placement and rerunning the pinknoise/eq...then always having to adjust the bass/mid/high parametric tone controls on the pre-amp for different types of music....i guess the whole system always sounded 'loose' and bouncy in my room
so one day i was reading how some people had turned their Magnepans around backwards(to "listen to the mylar side") and during the course of trying that, i also wanted to try lifting them up slightly off the floor about a foot and getting the panels perfectly vertical....and that helped some(I think mostly raising them and getting the tilt out so they were flat) which helped in my room
after trying like that for awhile, I decided I would rather look at the fronts....so went to turn them back around, but first rotated only part way back around and shoved them back into the corners out of the way so i could vacuum....had the vacuum running so turned up some tunes, then when i was done and putting the vacuum away i was like : "whoa, wait a second...that sounds good!" ....and started playing with the accidental placement i stumbled on, running the 31band pinknoise room eq produced the flattest(least amount of correction) curve I'd seen yet....and the center sound stage was not only fantastic, but the 'sweet-spot' listening area became huge..... i know there has to be some strange sound wave cancellation maybe going on, maybe, but I'm not getting a muddy or sloppy effect...and everything seems tight, refined, and clear...I no longer feel much/any need at all to fiddle with the tone controls for different volume levels nor styles of music....low frequency bass dips and peaks(caused by the room dimensions) have been smoothed out, and one spot in the room where there was a 50-80hz 'hot spot' is so much less now
....the far side of this room opens up into the rest of the house(stairway, open hallways, and on to other rooms) and often the music will run while we are further away in other rooms...and it still sounds even, full, and clear
...i dont want to get too particular about what my hardware is, or why this might only work in my room architecture or treatments....i just want to better understand a theory on whats going on here; with my megnepan panels at about a 45° angle coming directly out of the corners of my room
here is a quick drawing overview:
so i also want to know what happened with this:

* Split center signal, run both inputs into L and R inputs of A21
* Out of A21, run each into an input of a DWM.
* Out of one DWM high output into a CC5, and out of the other high output into parallel MC1s that go on either side of the screen (2 ohms at > 200hz, but Parasound said A21 should handle this).
Will check back in after I set it all up and experiment. Has anyone an empirical opinion on the tri center? My early experiments have been mixed.
yeah, i just posted about my 3 speaker center channel setup here Dual center channel speaker setup
its not nearly as complex as what you are doing(really arent you doing a total of 5 speakers including the two DWM bass speakers) and i dont have space for my Maggies in my HT room.....but i hope you were able to get some forfilling results like i did
