Speaker distance

@geoffkait , "I would be remiss if I didn’t say that there’s an infinite number of speaker locations for a given room, so obviously the ye olde trial and error method can only get you so far. You can NEVER find the absolute best locations that way."

You make a good point for most people. Although this may sound controversial, ONE AND ONLY ONE best location to site the loudspeakers exists in a given room for a system. That doesn't mean there's only one single point in the room, as altering components changes that position.  It works exactly like focusing a lens. When you find it, the sonic level of the system jumps to a point otherwise unreachable.  Just like a lens, it's immediately, obviously, and infinitely more right than anything else.  It transcends so many of the dollars folks spend on supposedly better components. This doesn’t normally work for most people, as the complexities of life gets in the way. So unfortunately, they don’t even come close to realizing the capabilities of the system they already have

ESP speakers are 7ft 4 in. apart center to center in a 14 ft wide room, toed in at 37 degrees.  The projected axis cross at 6 ft out which is about 4 ft in front of my seated position.  

There is no "hole in the middle" effect and the sound stage is wall to wall.

Just curious, did any of the above responders know their measurements or did they actually have to measure before posting?

I'm not sure if there are an infinite number of loudspeaker/listener placements, but there's surely more than one in any room that will work well.  Different positions have different sets of trade-offs which some listeners may prefer and others not.

I knew my distances. My room is less-than-ideal, so using an odd-dimensions placement is pretty critical. The acoustic centers of the speakers sit at the 1/5th and 1/7th intersections. The listening position (approximately) falls on odd-dimension line as well. I have 2” pressed fiberglass at the first reflection points, as well as behind the listening position. Toe-in points the speakers just over the shoulders.
