I would check into these as an option as well.

They are a very high quality speaker. The B&W 685 would be on my short list too.
WOW! Those are some killer looking speakers.

Matching center. I can't find the port information for this center, but with a +/-3dB limit of 55Hz, I would guess it is not ported at all. It uses two of the same drivers that are in the bookshelf model, so that is how I come to my assumption.
