The listening area is along the long wall, but not in the center, because the couch would block the stairs going up if it was also in the center :P The room is approximately 4m by 6.5m.
And at 30 Hz, the difference between the width of a door to the corner and an opening in another corner makes what difference in corner loading ?

If it were my choice, I'd have the speakers on the 4m wall, unless some other household Feng Shui got in the way, because I hate longer (and non symmetrical) reflections coming from the side than behind, sounds "goofy" to me.

I thought about trying to do that, but along the short wall, I'd only have one corner on each side, the front door is on the short wall and so is the opening for the kitchen on the opposite side.

I guess it is kinda a feng shui thing. Every time I have a few drinks I threaten that someday I'm going to make the 5m x 6m addition of my dreams with only one door at the halfway point of the rear wall :P

fyi: 1 meter difference away is = to ~3 ms of delay at 68F


edit : to be exact, at 68F sound travels 1 meter in 2.915 ms. (as a general rule i just remember 1ft = 1ms).

edit ps, if you want to be really anal... from prosoundweb

Although typically people measure for group delay for a measurement that's approximate to "responsiveness" or "fastness".

Though the audibility of group delay is debatable.

Why, pray tell, have you revived a thread that's 18 months old?
