How to use a Magnepan as a center channel ???

Hi,

I'm new here, sorry if my question is already answered somewhere else...

I recently found one Magnepan (Magneplanar SMGa), in the garbage near my home (!!!). No sound came from it, but then I changed the fuse, and GREAT SOUND !!!
that was the entertaining part of the story, now the technical.

as I already have a nice sounding pair of Spendor Prelude, I tought that adding the magnepan as a center channel would be great. I do not have a surround system : my amplifier is a Pioneer A9, huge power and great sound, two pair of speakers can be connected to it.
My father being a fellow reader of The Absolute Sound advised me that you could help me in solving the issue of how to wire things so that I could get a nice center and two sides without fussing the phase, etc.
Also, the well known fact that Magnepan are always power angry, much more than the Spendor. The Magnepan is 4ohm. Is there a way to make them equally loud ?

by the way, I'm using my sound system with various music styles (from hip-hop to classical), sometime for watching movies. Also for studio use as I'm producing some music and I don't always use headphones... :-)
So keeping the straightest response curve and lowest noise floor is the ideal.

any ideas on how to proceed ?

Thanks a lot in advance
