Just to further muddy the waters, for a Sub I got an Outlaw LFM1-Plus and have been thrilled with it. I had it shipped to a US Company in Blaine that specializes in cross border shipping/receiving. Picked it up there and drove it across the border (I live 15min from the Border near Vancouver).
Bought it on Sale (10% off + Free Shipping) picked it up and drove it across the border ($60 Duty)
Had to find and silence all the stuff in my room that rattles and vibrates... but if that was the biggest problem I had...
