I am awaiting my new Onkyo TX-SR502 receiver to replace my old Sony component based system. My living room is approx. 18'X 20' with a 10' ceiling. Floor surface is hardwood. The room is open on three sides to adjoining rooms with 8' ceilings. Basically I have about a 2'-3' wall space from the ceiling down on three walls of my living room. I think I need some decent size speakers (bookshelf size or larger) to make this system sound ok in this room. I am considering purchasing the Onkyo SKS-HT520 speakers ($350) (this is the price range I am looking at right now. I see a lot of recomendations for the Athena speakers and others that are satt. speakers but not meant for larger areas? So what do you suggest for a very budget speaker setup for this large room with budget receiver used primarily for TV/movie viewing? The rear surrounds will be wall mounted, and the front Mains will be on large inset shelves (rear ported not good?). Thanks, Tom
