Yeah. Since the surround back is causing problems and are bookshelves which do not need to be wall mounted. All you would need is like 5 feet of wire for each speaker. Placement of the HSU horns does not matter during the test since it is just a matter of seeing if the receiver will shut down again in 7.1 mode with different wire.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
