I will be upgrading from my Heresy II's soon and decided instead of going first to something like the La Scala or Cornwall I am just going to take the plunge and go for the big daddy. I do have a couple of questions:

1. Should I buy new or used (I am so scared of getting burned on something so expensive, I have been burned on cheaper as-is type deals before)?

2. If I buy new, are the horns plastic? My father-in-law has some old La Scalas with metal horns and my Heresy II's are plastic, when I am playing newer electronic/techno music the horns will sometimes resonate with the beat (as well as the plastic terminal on the back). The La Scalas sound great with any music, at loud volumes (you just have to worry about vibrating things in the house).

3. New or used...should I upgrade the crossovers? Is this only for used or is there any advantage in upgrading new ones? I think Bob Crites are the ones I see online the most.

4. How small of a room will these work in? I am using a 10'x15'x8' room now that is soon to be devoted just to audio (only my rig and LP/CD collection). I am buying these speakers to have for decades (I am 32 now) so when I upgrade houses down the road I plan on using them in a more suitable room, I just don't want them to sound bad in a room too small.

Any info greatly appreciated.
