Well all I can say is that the channels are definitely delayed from each other so unless those digital time alignment systems do something else (I doubt it) then it should work.

You should be able to close your eyes and feel like you're sitting in the middle of the car. Try setting it to zero delay and put your head over the centre console (probably right in front of your empeg). That's how it should be.

Speaker placement and setup (splits vs coax etc) will make a fairly large difference I would expect.
