Suggestions for optimizing Argent Room Lenses?

I've tried placing the left and right outboard Room Lens as recommended by Argent, but to me this positioning doesn't seem to let the Merlin's "breathe" naturally (i.e. they seem to alter the soundstage the Merlins throw in a manner that just doesn't seem natural to me).

I am currently experimenting with corner-loading the Room Lenses in the left and right corners behind the speakers. Any tips from anyone else who has tried this configuration?

I have my lenses positioned as I described above, and my system throws a soundstage 4 feet wider than the lens positions. That's 4 feet wider on each side. I don't think that the lenses are limiting your soundstage.

ive had mine placed just as twl explains in his post,the center lens will control the depth of the soundstage,IF that gives your system too much of a wall of sound,try placing 2 lenses about a foot behind an imaginary line,behind & to the outside of the speakers,i found i got less digital glare from my system this way

Room lenses are not designed for use in the corners. If you use anything in the corners they should be bass traps. I have been using 3 lenses for a few years now in a similar fashion as described by Tom (TWL)and they make quite a difference with my Aerial 10Ts.
