Hi Everyone, I have a question that has been worrying me over the past few months. You see I bought a set of speakers for my modest HC setup: Eltax Symphony 6.2 Eltax Symphony Centre Mordaunt-Short Bi-Polars (rears) All linked to a Pioneer VSX 709 RDS reciever. My room is a square in shape, so if u can imagine it forms the 'typical' surround sound diagram...my worry however, is with my bi-polars. I have them set on typical speaker brackets that are bolted to the wall approximately 2-3 feet above ear level. A few months ago whilst watching a dvd (Next Friday)I was alarmed at the distortion/rattle coming from them. It sounded as though they had blown. How can I know if they have blown for sure? Do i have them set up correctly? What direction should they be pointed towards? My cabling is half decent oxygen free stuff but what would sort would be better for this setup? Thanx, for listening, Can somebody enlighten me please? Emissary.
