The older NHT's were designed to go up against the back wall - the 3.3's and 2.9's. They're a big, somewhat uniquely shaped speaker, but even so only extend into the room so far, certainly not further than most speakers when set out in front of the front wall.
The Allison Model 3(?) is designed to go directly in the corner. Never heard them, but they're certainly friendly to the room :-)
