well, If you boosted the center channel up (this would not be under calibration, but more preference) a more efficient center would be a better option.
The AS-C1.2 should match well with the point 5's, as all Athena speakers seem to carry the same, bright sound.
If you wanted, the old fronts you had could go as rears and you could have a 7.1 setup with the Audition series up front and the point 5s in the rear.
