I recently purchased a pair of M60s, VP150, and QS8s. I'm extremely pleased with the new setup although I do have a question for the more learned souls on the board. I want to broaden the sweet spot when listening in 2 channel. Due to some room constraints I have seating spread out over a fairly wide area. As it is now, my sweet spot is about 4 feet wide. The two M60s are 8 feet apart. They are a little over a foot from the back wall and 12 feet from my usual listening position. I have them slightly toed in towards the sweet spot. I played with the positioning some but have yet to hit on the optimal placement. Any tips or tricks that I may be missing?

Thanks,
