Hmmm, whatever toe-in will have to be within the 98" width I have to spare. My setup will be in the living hall which explains why I'm curious about the 3677 vs LSR. The LSR piqued my interest due to its smaller form and affiliation with M2. At the same time, the midbass slam of the 3677 and the CD is very alluring. I plough through the LSR thread, not much discussion about its performance. Probably cos its newly released I would think. Right now, I guess I'm with the 3677 until someone who heard both can weigh in and comment. Cheers!
