Lee,
I'm in Canada as well. I used to own the smaller version of the SuperTower's - Tower II/R. Key was to control the woofer with these speakers. Lots of good quality power worked for me. I used an Audio Research 350W solid state amp. Best amp on them, that I tried, was a Threshold S/300.
When I had the RM2's, I had a Cinenova Grande, like Brax's, driving them and it did a really good job. Give it good power and you'll easily tell the difference.
They were / are good speakers.
