The Gradient Revolutions are supposed to sound great next to a wall - I have not heard them, though. I would avoid having to move speakers all the time, if I were you. To me, the NHT 2.9s sounded like crap the one time I heard them (at hi-fi '98). I don't like Meridian speakers either, but some people do - and they have built in equalizers so that you can ajust them for wall placement.
Speakers to beat wife-factor ?
I'm looking to replace my Klipsch Forte's with something more refined, but wife-factor requires placement very near rear brick wall, in a 12x14 room (England). Child-factor requires floor-standers -- boxes on stands wouldn't survive. Would like a Maggie-flavored sound, but is there anything that can deliver with its back to the wall and its feet on the ground? I want to keep the solid bass I have now with the Forte's, but want to improve the rest of the sound. Is my quest impossible?
