Also, this lets you maximize the distance between the rear wall and your ears. If your rear wall is reflective, it should be at least 10 feet from your ears… otherwise it needs treatment (more on this later)."
I have Reaction Audio CX-10s, with (supposedly) 90* conical dispersion. I'm about to put them into a rectangular room that's open near one end (the corner has an opening to the kitchen). I'm considering either putting them on the short wall of the closed end of the room, or on the long wall. But that would only leave a couple of feet to the opposite wall behind me. From the article, I get the impression that it's really important to avoid sitting near the rear wall, and that is why they recommend putting them on the short wall, even though that will put them in closer proximity to the side walls. They're probably also assuming said walls will be treated, and there is no guarantee that I'll be able to do that.
I'm wondering if you don't treat the side walls, is it still generally better to go with the short wall? If I had to guess, it's 11-13 feet by about 20 feet.
Those of us who have to make do by using multi-purpose rooms as listening rooms, rather than having dedicated home theater rooms, must work with what we have. In my case, my 19.5' x 16.5' room cannot have a layout with the speakers on the short side, and I have large openings to the rest of the ground floor at the back of the room.
I think the article states that, if you can do it, orienting the layout so that the speakers are on the short wall, and keeping a reasonable distance between the MLP and the back wall, results in the best sound. But the article also states that if you can't do this, using well-placed, effective treatments can help overcome room layout challenges.
Even with my less-than-optimal layout, I have been able to achieve quote good bass response using treatments, multiple subs, and effective equipment placement, which provides an example that good results should be achievable for anyone who is willing to work for it.
