My SVS 20-39PC just arrived yesterday and I am blown away. I can't believe it took me this long to get one. This is the first "real" bass I have heard and now can have the sub calibrated at 80db without it hurting my ears. I actually have the volume at 5 which was impossible with my previous sub because the boominess would hurt my ears. The seats rattle, the bang is there which keeps you on the edge of your seats, all while not hurting your ears. THIS is what home theatre is supposed to be. To any Canadians worried about the exchange rate, GST and duty, I know it's a pain but truly worth it when you can add a sub or two of this quality to your system. Highly recommended. Thank-you SVS!
