I guess you saw this
http://www.audiocircle.com/index.php?topic=120643.0 , but are your referring to the 4.1 Prism like this

or the special Center 4.1 Prism like this?

If this one, here is a good candidate,

I have the Prism 3.0s in Teak. They have the little Fostex drivers but they really sound great, they seem to integrate very well with other nOrh speakers. I have used them as rears in HT, and have even fooled my friends using them as mains sitting next to Marble 9.0s for a demo. That merely shows how most people are clueless, but these little Prism 3.0s are good enough as mains i guess for 99% of the world. We are the audio 1% OR .1%

What will your HT mains be again?
In my mind half the fun of a HT is to have an exotic/eclectic dedicated theater environment. As a center, this speaker would certainly fit with that approach whichever style you go with. Center has mostly voice and ambiance so not as much is demanded of the center.

I feel you would be very pleased with the 4.1s as a Center. Of course they would be much better than the Prism 3.0s so would match better with your nOrh mains speakers. I always wanted to try the 4.1 Teak myself but saved my money for the Marble speakers.
