I recently purchased some used Klipsch RS-35 rear surround speakers. After hooking them up to my Yamaha receiver I noticed that the left horn on both speakers had far less midrange sound than the right horn, almost all very high frequencies. I was wondering if anyone has had experience with these speakers and can tell me if the two horns are crossed over at different frequencies or if they should sound identical and maybe there is something wrong with the horn or crossover? Thanks for you help.
