Looks like we are neighbours, I live in St-Bruno. I finally ordered a VTF-15H from HSU this morning. If everything goes well, I should get it by the middle of next week. Can't wait to get this baby
LFM-1+ looks to be a good dub for the money. What is your setup configuration (equipment, room size, etc.)? I've been running dual subs for the past 2 years and twins definitely sound better then one (of the same subs). The problem with my Velos is that I was laking deep extension (below 30Hz the response was lame).
It will be my pleasure to invite you for a demo as soon as I get my HSU and maybe it'll help you decide if, like me, you go with a single more powerful sub with the possibility to eventually add a second one or you go with a pair of less capable subs and are kind of stuck with them...
