I have the M22's and M80s, have compared the M60s to them both and if price is not a concern go for the M80s, if they are too much then M60s and finally M22s. You could go with either the VP100 or VP150 for a more traditional center, as each sound nearly identical to each other and blend very well with the mains listed. The VP150 does have a slight edge in that it plays a little lower than the VP100.
I have the PB13 Ultra and it will rattle the foundations if you want it to, you could also go for the EP600 for a slightly smoother more encompassing sound, inspite of the reviews to the contrary elsewhere, the Axiom subs are very good and hold their own when directly compared to the competiton.
