I've bought speakers online after reading as much as I could about them and after auditioing at length with music I'm familiar with and there's really no comparison. You have to personally audition them.
Having said that, if there's a speaker you don't have access to and you really would like to hear it or something from their line, talk to the company and see if there is anyone near you who've bought a pair and maybe they can hook you up with a listen. I've done it once and it was a very nice experience and I ended up buying a pair online afterwards.
Good luck in your search.
All the best,
Nonoise
