I don't think you are likely to hurt the VP150 running it in Large but you are probably going to miss out on some low frequency content on the center channel. If you set the center to "small" then any LF on the center channel will be routed to the subwoofer.

There isn't normally a lot of LF content on the center channel but every so often there seems to be quite a bit.

I would stay with "small" personally. The VP150 is not designed to reproduce all frequencies, just to do a great job down to where the subwoofer takes over.
