I have a Kenwood NV-701 system. Over the past few months I have had a problem with the DTS setting on the stereo. When watching a film or listening to audio cds encoded in DTS, there seems to be no or very little bass from the subwoofer, but when I listen to a DD 5.1 soundtrack, there is no problmem at all.
I found a post on here that mentioned when watching a film the subwoofer should be set to +10DB and have tried that and found that DTS sounds good but when I switch to DD 5.1 the bass is very heavy. I can also set the system up for the size speakers I have (Large or Normal), and this seems to have no effect at all. The simple solution would be to change the volume of the sub every time I want to listen to a different sound type, but with long menus to go through, it tends to get annoying.
