Among current makers, look at Larsen (all models) and Klipsch (certain models). Vintage speakers that were designed to go against the wall include Sonab-Carlsson, Allison, and certain models by Snell, and Linn (the Kan, I believe). I have not heard the new Volti.
Speakers good for close to wall placement
There are quite a few speakers I would like to purchase, but I need to be realistic. I will need to find some speakers that perform well when placed close to the rear wall. After that choice I can move on to selecting the proper integrated amp to drive them. Any suggestions on which speakers work well near the rear wall?
