Well, I decided and Got the Onkyo HT-SR800 for 300. Sounded great, then I got 16 gauge Speaker wire for the Fronts and it sounded so much cleaner. If I upgrade the Subwoofer Cable would it be worth it? I heard people use RG6 for Subwoofer Cable? Are RG6 Coax Cables that give me signal from Cable Companies?
