I should have been more specific about my system.
My fronts are 4 ways that have usable output at 20hz and by 25hz they are kicking. I'm biamping my fronts so my 5803 only sees them on the preouts.
My fronts go to 60hz, my sides go to 28hz, and the rears go to 50hz.
The sides are also sitting on self powered 10 inch velodynes that go to 25hz or so.
The subs are A D S ms3 and ms4 in front and are run of the sub preout.
The 5803 enables main+lfe for the front which I have tuned for music, but when I play a movie I want more thump so I just turn up the sub channel, to get the full output of the front subs.
I can use the 5803 analog inputs with dsp but then I'm doing the digital to analog to digital to analog thing, not sure how it would sound.
I use the analog outputs of the oppo to take advantage of the new surround formats and when you set the fronts to large and subwoofer on, the sub does not work.
If I set the fronts to small and sub on all works but crosses over at 40hz being the lowest.
I'm currently trying some other options but over all if this is my only complaint this is one heck of a bd player.
Oh and I think the picture it throws on bd is great also.
