The flexibility of the Onkyo listening modes is nice and allows you to customize your sound on what you like best depending on the source.&nbsp; The Onkyo customer service was very helpful too with some ideas.</p> <p>Have fun and good luck!</p> <p>Larry from Dallas</p>http://community.crutchfield.com/forums/p/8802/40123.aspx#40123Fri, 15 Aug 2008 21:35:34 GMTbd5cdc59-8905-44ac-b6bd-800f81497726:40123Paul<P>Given the testing that you have done, it very well could be the receiver. However, I know that Bose Acoustimass systems have the bass module that the speakers run into. If you have one of these systems as your theater system, then it could be the bass module. You may want to try connecting the left surround speaker into a different channel to see if you still have the issue. If you do not have a Bose Acoustimass system, then it is most likely the receiver going bad.</P> <P>Anyone have other ideas?</P>
