I currently have R50's as L-R mains, R30's as surrounds and (unconventionally) a pair of R15's (wired in series) as center. The 2 R15's wired in series seems (to me) to work very well as a center. I must say that as a relative newbie to the modern A-V world, I'm extremely happy with the sound quality of this setup -- especially the R50 mains.
My unconventional (yet -- to me -- successful) approach to the center channel -- combined with the VERY attractive price of R-50's currently available from Fry's Outpost has me wondering about getting another pair of R-50's to add to the current R-50's at the L-R main position.
I have a Pio Elite VSX-72TXV AVR that has no trouble diriving the current setup to hearing impairment sound levels at -10dB to -3dB ("on the dial"). For serious HT or CD/SACD listening I normally use a non-WAF level about -20dB to -10dB -- depending on the source. So I think I have a bit of unused headroom left in the AVR.
What I would like to get some opinions about -- I'm thinking of the further unconventional step of adding another pair of R-50's to the L-R mains -- wiring them either in series (probably) or in parallel (possibly) with the current pair of R-50's. I'm thinking that that a total of 8 6-1/2" drivers in the front would present a very full and rich sound stage -- and given that it would only cost an additional $170 delivered it seems worth a try. Even if I'm wrong and it turned out to be a complete cluster f***, worst case is I could just use the 2 new R50's in place of the R30's as surrounds, and use the R30's as SB's.
What do you think of the idea of using 2 sets of speakers wired together at each of the L-R main positions?
