Speakers good for close to wall placement

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.

saw this just now

as mentioned previously

Since all rooms are different makes them a moving target, with peaks that vary from plus 12 DB on one channel and normal or minus 4 DB on the other if your serious about performance then DSP wont do. For many years we have been successfully installing dozens of Vandersteen phase and time correct speakers tune able in your home with superb results.Yes even 3 inches from wall and in corners!!Their adjustments are easily done in the analog domain taking music, performance and confidence in your system to another level.   Best, JohnnyR
