Perfect Speaker Placement - Put next to the back wall as much as possible.

I thought it was a good article mainly talking about small monitor speakers in a nearfield listening position with bits about larger speakers thrown in. For small speakers, I would suggest his recommendations. I have done it this way with good success. But for larger full range speakers, you need the speakers out from the wall, way out. There are many articles on speaker placement and for example the Cardas method, he states recommendations for planer speakers and for box speakers, nearfield or not, and for square vs rectangle rooms.
The Wilson duette speakers sound very good up against the wall whereas the Wilson Alexia 2’s would not.
I also agree with audio2design and many others on these forums: never listen to millercarbon. I think it’s outrageous that MC compares his low fi system with Mike Lavigne’s system, that’s an embarrassment to Mike.

To clarify it is your ears that are supposed to be at 38% from the front wall or the back wall. Nothing to do with speaker placement.

"B I G difference."

Oh?  How so within the framework of acoustics or perceptive differences?

 I don’t think there is any such thing as "perfect" speaker placement as long as you have them in a room with people, furniture, and pets. However, any of the major speaker placement formulas may improve your set up just by (a) getting the speakers away from the walls, (b) introducing symmetry in the relationship between speakers, walls, and listening position, (c) ensuring that the speakers are not equally distant from boundaries in more than one dimension. Beyond that, I’m skeptical that there necessarily is anything dramatically better about one of these formulas than another (Rule of Thirds, 38%, Cardas, etc.)

I’ve found that the Allison Rule is more flexible than others w.r.t. furniture placement. The Allison Rule (as I understand it) depends on 3 measurements, namely height of the woofer off the floor, distance of speaker front face to front wall, and distance of speaker front face center to the side wall. It states that the middle of these distances should be the square root of the product of the least and the greatest of these distances. So I place my speakers about 4.5 feet in from the side walls; midpoint of the 2 woofers is about 2 feet high; the front face is about 3 feet out from the front wall. That is, 3 feet (the middle distance) is the square root of: 2 feet (the least distance) times 4.5 feet (the greatest distance). The point is to maximize the differences among these 3 measurements, within the constraints of room size and speaker placement, in order to minimize room effects.

By "back wall", the OP seems to be referring to what other audiophiles usually call the "front wall", that is, the wall directly in front of the listener (and behind the speakers). In my experience, placing speakers very close to that wall may improve bass extension, but generally is not so good for imaging/soundstage. I prefer to pull speakers away from the walls and increase bass extension by adding a subwoofer. Also, I use highly directive (focused) monopole, sealed, hybrid electrostatic speakers. These tend to minimize room effects. I get a very sharply focused center image along with a rather flat frequency response between about 10hZ and 15kHz+, without any room treatments (other than furnishings) or PEQ. Then, to widen/deepen the soundstage, I use BACCH4Mac software.

To clarify, you guys are saying that your speakers are 38% into the room and your listening seat is also 38% into the room? This seems like it would be a nearfield setup in anything less than a 40 foot deep room...

Yes you are right... In my case i must say that owning a small room , my nearfield position at 3 feet+inches of my speakers and/or at 7 feet of them in regular position, this golden number rule of Fibonacci is perfect: 62 % ratio to 38%...

But compared to most i which own more bigger normal living room for example, my 2 positions are really almost 2 near-field one that work well one or the other, BECAUSE of this ratio in my square small room....

The difference between the 2 positions in my case, i love the 2, is a slight change in the relation between dynamic and imaging... Imaging better possible at 3 feet and dynamic better possible at 7 feet....But soundstage holographic and relatively comparable timbre and decay in the 2 positions with only an accentuation on details in nearfield and an accentuation in bass frequencies dynamic in my regular position... I love the 2 without being able to chose between the 2.... There is difference but nothing really is lacking.... A sure sign of a good acoustical setting in my case...

Then in my room the golden ratio win the game....
