I recently purchased a used Klipsch THXUltra2 system (http://www.klipsch.com/thx-ultra2-home-theater-system
). The previous owner had a 9.2 set-up, so he added an additional pair of the KS-525 (http://www.klipsch.com/ks-525-thx-surround-speakers-pair
) to the original 7.2 package. Unfortunately I am running my current system with an SR7005 which limits me to a 7.2 set-up at most.
Instead of just having an extra pair of speakers lying around what I planned to do was run the additional pair of KS-525 in parallel with the surround back speakers, effectively making it a 4ohm load for both the surround back left and surround back right, channels. I don't really think this would tax the receiver too much as the surround back channels generally don't demand that much power, especially considering the size of the ks-525s. My hopes are this will broaden the surround back sound stage.
My first question is, will my receiver be in any danger? Secondly, is this a dumb idea or does it have any merit to enhance my listening experience?
I know the easy answer is to purchase a 9.2 receiver, I am not to fond of this idea as I just purchased the SR7005 in August before I came upon this killer deal on the THXUltra2 system.
