I will be purchasing a RC-52 center and RB-51's for fronts (for a 7.1 setup) due to size constraints. What would you recommend for the sides and backs? I was thinking RS-42's for the sides, and was wondering if I could get away with RS-10's for the rears for aesthetic reasons. Is it better to use surrounds or bookshelves for the sides / rears? For the sub I was thinking either the RW-10d or RW-12d. Thanks in advance.
