that's not going to work on my stairs, especially with the sharp right angle turn half way up them :( My sincere advice - hire some piano movers. That's what I did when I got received my Salon 2s, and they're small compared to your new monsters. Sure, it was $300 including a nice tip, but one little ding and I would have been broken-hearted, and why take any risks with hyper-expensive speakers or a back with bulging discs?
