Kevin: Interesting development! I turn my 2 amps off(a 5ch and 2ch) set to large and put on LOTR EE and chose DTS ES. Played the first scene that has incredible bass content, but nothing coming out of sub. I then went to menu and change surround from large to none and bang . Bass and more bass! I then toggled back to large, expecting to lose the signal, but it remained perfect. I cant explain why it did not work in DTS ES initially, but it certainly worked perfect following the sequence I performed. There is something strange about it, and would not normally discover such abnormalities since I prefer to run small all around and Xover at 80! Thanks for the info!
