Sebrof,
My current speakers are the overacheiving Vandersteen 1c's.They use the nut and screw method to provide tilt back....don't know why I didn't think in that direction, glad you did. Thanks Gpowered for the other tilt option.
The Lores seem to change sound character more than the 1c with a change in vertical listening position. Tilt back should help.
As an aside, I really like the sound of these speakers. The midrange is detailed yet non fatigueing. A gem of a speaker and worth the high praise I've seen.
