No. The suggestion that I made will destroy any HTIB. The Behringer speakers are great for the price - even better if you'll put 30 minutes each into tuning them up a bit. If you want a better sub then save money by just buying 2 pair of speakers for now and build a 3.1 system, and then add the other pair later.
I have no clue what bargain subs are available in Canada but a few people here are happily running $150 Dayton subs in small rooms like yours. I haven't heard one myself so I can't attest to the quality. Maybe somebody else can help with that.
But if you must have a HTIB then I'd look at the
Onkyo HT-S7200 - but only if you don't have people below you. The down firing sub will make downstairs neighbors crazy.
