Speakers good for close to wall placement

Depending on your space, an Ohm Walsh prefers to be at least a few feet away from a wall/walls...  Some have a small 'footprint', so that may not be an issue.
They can be a bit fussy, being at heart an omni.
If you absolutely have to be on the wall, walk on by.... ;)

Happy hunting, J

The Scansonic MB1 B, MB2.5 B and MB3.5 Bs are all designed for near wall placement.  
When Michael Borrensen left Scansonic/Raidho the Scansonic line was completely redesigned so that the break-in time was radically reduced and the three models were explicitly designed to work within 1’ of a wall.

Not theory.  In practice, this happens.  I have a customer who put MB3.5 Bs in his living room.  Has them like 9” from the back wall and they are wonderful.  I helped him set them up.  

He uses a PrimaLuna integrated in triode to drive them which is like 35w.  
These check all your boxes and deliver a huge, immersive soundstage.  

+1 on the Vandersteen Quatro Woods. Mine are 8" (back) and 10" (side) and sound great

It sounds from your requirements that Vandersteen or especially Cube Audio would fit very well.  We have both speakers for demo.
