I was a dealer for Magnapans in the past, and have some experience with them over the years. Might I recommend keeping those music speakers for 2 channel music dubties in that system, and doing either one of two things. One, keep the 2 channel system separate, and integrate a 7.1 channel small satalite system, that'll give you seemless, properly integrated results from your ht system. The other is to simply add a subwoofer to your Magnapan setup, and add a processor. Adding different brand speakers is a sure path to low fidelity, different overall sound - as things pan from speaker to speaker - and not to mention it will all look cheap!
Also, listening to any Magnapan speaker "off-axis" will yield less than stellar sonics. Believe me! Sound will be rolled off and hollow. The only way to hear maggies, is sitting dead between them. In that case, a need for a center and rears, is really not so important, imo, due to design limitations.(they're dipoles, and phase cancel out off-axis...it's how it is)
Keep it simple if you want to stay with the very low efficiency and rather delicate 1.6's for dynamic movie mixes, definiltey add a powered sub, and cross the maggies above 80hz.
Anyway, those are my two setup recommendations.
