By the time you get through shipping and brokerage fees, that Hsu will no longer seem like a bargain.
There are dozens of great AV stores in the GTA that will give you a deal on a sub. Replay Electronics used to sell Axiom and may have a few subs remaining at rock bottom prices, or last I checked carried Dahlquist. Bay Bloor carries Def Tech and Energy (though you're not likely to get a great deal because of their top-flight service). Audio-One on Steeles at Hwy 400 sells Paradigm and others...they also have spectacular buys in used and consignment gear.
Just shop around and have fun.
