The biggest problem with going high end imo would probably be that anyone willing to spend $5-10G (or more) on a pair of speakers is unlikely to purchase over the internet without a thorough auditioning first. That's where the dealer network takes over and hikes the price up another 50%+ (or whatever the markup is). The current pricepoint of Axioms takes much of the worry out of purchasing sight unseen (heard/unheard?) for many people. That doesn't mean to say that Axiom shouldn't experiment a little, say with an "Anniversary Edition" bookshelf or something like that, it might give them some idea about whether an 'upmarket' line would work, but it should certainly be done cautiously and not detract from their bread and butter lineup.

Half of communication is listening. You can't listen with your mouth.
