I'm a couple weeks out from ordering my Axiom speakers (M60s, VP150 and QS8s) and I need a good sub to throw in the mix. My room is 13' x 18' x 10' and has a 9' opening to the stairwell on the right side of the tv. I want a sub that will shake the walls during movies but still provide tight harmonious bass with music.

My budget is around $1200 Canadian. Subs I've looked at:

EP500 - right at my budget, made in Canada, good warranty - is it it really 5 years including the amp? matches speakers. My only concern is the price seems high compared to the competition.

A5-350 - looks like a beast, made in us - with shipping and gst, total would be around $1050, warranty is only 1 year on the amp

SVS through sonic boom - concerned that amps recently changing over to DSP but I believe sonic boom is still selling old stock

HSU - to much to ship to Canada - VTF3 would cost the same as a5-350 despite selling for 100 less in the US

Epik - looked at the Empire - haven't looked into shipping yet.

To all you axiom owners out there, what sub(s) are you rockin?
