Sorry, my reply above was based on my reading the request as "bi-amping" instead of "bi-wiring" - my mistake. Nevertheless, bi-wiring doesn't sound like a good idea because you'll be subjecting both types of speakers in the box (assuming a two-way system)to a range of frequencies for which it was not intended. This is because the filtering action of the cross-over will be eliminated. most centerchannels are designed to deliver good quality dialogue so I think best to leave alone.
