My room size is 16'6"x11'x9'. I’m trying to decide if it would be worth the extra 200$ to go with the m60's rather than the M50's and save on the surounds by going with the QS4's. Would you guys/girls say the M60's sound the same / better / worse given the same room acoustics, speaker placement, seating position, etc than the M50's? What are your opinions?

Thanks for the help
