I currently have a center that is not of the same brand/quality as my mains, so I rather have a phantom center generated.

If you sit in right between the two speakers, I see no reason why Trifield should not work without a center. I prefer Trifield without a center over direct. I just wanted a quick way to enable center channel when I have friends over or not sitting in the middle.

I have never used types.. are they complety individual setups that can be changed with the remote?
