Philippe,
Have just seen your set up and it looks very tempting! I am considering getting the Canterburys and Tannoy suggested they be placed a good 2ft from the rear wall and 2-3ft from the side walls. This might be a little difficult for me, and I can see that you have yours close to both boundary walls. Have you found any problems with this, or have you had to do any room treatment?
thanks
Michael
