Like I say - inches matter - it has to be practically touching both the side and the back wall. The pictures I see of the California Show it looks like at least a foot from the back wall and right next to the side wall. I dunno - I don't like My J positioned there - a little muddy and wompy in the bass - but I guess that's the best Mario could do with it.

I found this - on AudioAsylum http://db.audioasylum.com/cgi/m.mpl?...er+qvortrup&r=

Actually this one is closer but I still can't find the one that addresses the floor specifically and it was there someplace http://db.audioasylum.com/cgi/m.mpl?...er+qvortrup&r=
Everytime I see the name Richard "BassNut"Greene, I just want to cry. I really miss that man, he truly was my mentor when he was here.

Getting back to the issue at hand; it is my understanding (and it was confirmed by RG) that in order to get the kind of boost you are looking for the room has to be totally sealed, and the room dimensions must be able to support any boost at 23hz and below by its length(it would have to be at least 25' down a wall for a boost at 23hz). So it would stand to reason that in smaller rooms less than 25' in length, you are not going to get much support at 23hz, and that boost that AN relies on won't support a 23hz extension. As the room gets smaller and smaller, the cutoff point of the AN speaker would presumably get higher and higher. This is why I feel that the AN speaker did not have the frequency extension to reproduce the bass pedals of a Hammond B-3, the room was not big enough to get the gain. So that makes all claims of low frequency response a moving target based on the size of the room. Plus, the amount of driver movement to reproduce those low notes would have a doppler effect on the higher frequencies that the driver also has to reproduce. That can't be good on the upper bass and midrange frequencies when deep bass is playing through the driver. That is why it is better to separate the deep bass drivers from the ones playing the mid bass and higher frequencies(a subwoofer for example)

Also the walls would have to be stiff as bricks, otherwise it will release any energy to the other side of the wall and not provide much boost at all. This is especially so

The second issue is having a speaker that close to a wall really does effect image depth, as you are effectively using the walls and an extension to the front baffle of the speakers, and in setups like this, image depth is compromised in favor of bass boost.

Richard Greene also makes another point, and it completely correlates to what I heard in the AN room. Corner placement is most advantageous to the upper bass, much more so than the deepest bass. In the AN room, every piece of music with the male voice, every piece of classic music that had lower strings, and brass had either a chestiness, or sounded overly ripe and much too warm than reality would have them be.

Just some food for thought.
