I've used Thiel's for almost 20 years now. IMHO, Mstram offers very good advise, long wall placement has worked better for me as well. In my experience the distance from the side walls is more important than the distance from the back wall. As you've noted, too much toe-in can be a bit fatiguing. Having the side walls further away can allow for a more straight forward position. As long as your ears are at least 8' from the drivers you should be fine regarding driver intergration. The only thing you'll need is a generous amount of sound absorbing room treatment directly behind you, when seated so close to the opposite wall. Give it a try. Good luck.
Help with Thiel 2.4 Placement
I have been struggling to get my Thiel 2.4's placed just right. Every time I think I am getting close, I find a something that sounded "better the other way". My room LXWXH is 20 X 11.5 X 8, with a carpeted floor, concrete underneath that. Drywall everywhere else. I am using Levinson 27.5, Levinson 38S, Levinson 36S, Theta Basic II.
Thanks
