That'll be a nice setup! I thought I had my crossovers figured out until I ran Audyssey and realized that my room had a major impact on frequency response. For example, Axiom specs had me wanting to cross my M5s at 60hz, but my left channel M5 has a major dip in response at 70hz, so 80hz becomes the ideal crossover point.
