dipoles on the sides and mono poles on the back :) But dipoles on the sides first. I'd say 2 to 3 feet above your sitting ear level which is around 36". I believe in putting surrounds above kid reaching height. So I say 6 to 7 feet up. thanks, so im doing either or, not both. only have 5.1, so would ya recommond doing side walls or rear wall? rear would be easier for wires and such but not a big deal. and cheap recommonds for surrounds?
