I think the HSU parts are made in Asia but assembled in USA or something like that..
Yeh, I hate that double shipping costs, then brokerage fees , then duty.
SVS has a Canadian distributor however again I have not heard there subs and can only go by what posts say. Same as HSU and AXIOM. thing is no it is not free trial on any of it, because if you don't like it you have to ship it back and testing three or four subs and sending them back costs.
