Allison and Snell - Against the Wall

I think there’s a difference between speakers specifically designed to interface with the walls for broad band dispersion, and those who have limited or tunable bass.

In the former I put the Allisons, Larsens, Klipshhorns and Snell.

The Wilson Tune Tots and Vandersteens and my own LM-1s in the category of limited or tunable bass.

Von Schweikert VR22, VR33 and VR35 were designed to go right up against the wall.  I bought a pair of the VR33 and thought they sucked, big time. Didn’t realize at the time that Greg Weaver must have been shilling for VS. 

NHT made some large floorstanders back in the day that were so deep, you could have the back of them snug against the wall, and the front baffle would still be 3' out in front of it.

Wisdom Audio makes an extensive range of in or on wall speakers using line arrays, planar magnetic drivers, DSP integration. 

PMC wafers- remember being very impressed when I was in the entrance hall at The Stables by the sound coming from a panel on the wall. Apparently they're used by the BBC as well.
