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

Ok, I feel like this is an extension of another post I just made in another discussion about imaging.
 I used to sell audio, I have some experience setting up different kinds of speakers. They vary dramatically in their optimal placement from walls. So no one rule works, despite acoustic treatments or DSPing being helpful. If you have a port in the back of your speaker, it behaves differently than a sealed acoustic suspension, which behaves differently than dipoles. Some are made to be against walls or made to be placed in corners (I sold Klipsch speakers). 

There has to be some type of program where you rnter your room dimensions and it will give you different speaker placement distances from the front wall in order to tackle specific dips.

Like, if you have a dip at 40hz, thats a 28 foot wavelength so at what speaker location will that wave cancel itself out at...


Room treatments are so huge in the way your setup sounds and once you get used to them theres no going back.  You just want to treat every square inch with absorption or diffusion.
I’ve been enjoying dsp as well.  Its kind of fun.  Its somewhat like changing speakers in and out without changing speakers in and out.  It allows me to still enjoy my high quality speakers but with just a different flavor of sound.

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...

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.

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