For music use, I believe that a good pair of floorstanders will give you the best overall musical experience.
For movies alone, a sub is a MUST and since you are usually crossing over at 80Hz, floorstanders are a bit of overkill.
As far as brand of speakers, I'm NOT a fan of Axiom after hearing them personally, and for sure you should hear them locally before you buy. I thought you got a lot of speaker PHYSICALLY, but their presentation and tonal quality seemed lacking to me. If you want to take the risk, just be aware that you will have to bear the return costs if you don't like 'em.
I believe you can do better by looking at the popular brands like Energy (should be able to get a pair of C-5
http://www.energy-speakers.com/v2/products/product-page.php?id=24# floorstanders for less than $600 after negotiation ($750 CAD MSRP) or all the way to the C-7's ($800 after negotiation, $1000 MSRP). If you're still itching for bass after these, then add a sub later, matching a sub is independent of which brand of mains you have, so you can add an Energy, Mirage, PSB, Paradigm, SVS, Hsu or whatever to fill in your low end.
I own Energy speakers myself, and am very happy with them after auditioning a large varieity of speakers. I did take the time to carefully compare them and made the right decision for me.....I do suggest you try them out at a local store for you AND compare them to others with music YOU are used to hearing (bring some favorite CD's). A lot of people will automatically assume that Axiom is best value because of Internet direct marketing, but just looking at the specs for M50ti, the C-5 or C-7 still seems like a better value (heavier cabinet, deeper bass) after typical negotiated prices.
I also like the Boston Acoustics VR series floorstanders, very nice for the money. Others that sounded pretty good were the PSB Image series.
Also factor in the cost of stands. A good set of stands (solid metal construction) go for at least $100 if you get bookshelf speakers.
