Well, I don't really know. But I'm glad you mentioned that (even though I thought I was done). My system never had a sub so I have no reference and I certainly agree with you. The BR dosent have a whole lot of setup options, I've tried everything that there is as far as output settings. I think this weekend I will try a dvd movie in my oppo and then move it to the BR and see if there is a difference in the LFE. Or could I measure the actual frequency of the sounds coming from the sub with a sound meter?
