I am currently running a 5.1 system on my Sony STR DH550 receiver. I have two Klipsch RF-10 up front, two Klipsch RB 10 (50 Watt) bookshelf for rears, and a Klipsch RC-42 ii for center. Along with a Klipsch SWV sub. (Note: not sure if it matters but the RF-10's and RB-10's were bought on Newegg and look exactly like RF-42 ii and RB-42 ii respectively. Rumors on reddit are they are re-labeled by mistake)
I was just given two Klipsch RS-10 surround speakers (50 Watt) from a buddy of mine. (Note: he also got on Newegg and they appear exactly like RS-41 ii)
My question is, can I wire up both the RB 10's and the RS 10's into the rear surround jacks? From what I have read online, it is possible, and the only draw back will be lower sound being put out of the 4 speakers. Is this true? I am ok if that is the only consequence, but do not want to do any harm to either the speakers or the receiver. Any input is greatly appreciated.
I know it is not the prime situation, but once funds become available I will get a 7 channel receiver in order to properly run the system.
Thanks for your time
