Yes, it all depends on the shipper. Anything sent USPS should not exact a fee. I've bought three folding knives (on three occasions) from a Canadian site and the postage for each was around $3.00 and I got them within 5 days. No problem, no hassle.
Something like your speakers can present a problem due to their size. You can't get around that. A few years back I sent an amp back to a Canadian site for a mod and was told to state that it was for repairs and never was assessed a fee of any sort, just the cost of the unit, size and weight. This was through FedEx. It went straight through with no hassles, both ways.
All the best,
