donaldekelly,
Generally they're being tested at 8ohm, it would suck even more if they were being tested at 4ohm and only put out 47w!! base on the THD rating it had to be running at 8ohm.
These Axiom and many many other speakers out there are pretty efficient, that's why it's hard to noticed when you severely under-powered them at moderate volume level, but sh!t will eventually hit the fan when you crank them up for extended period of time, just take it easy with the volume and back it down as soon as you hear those mids or tweeters distort and starting to break up, otherwise you'll burned up the voicecoils in no time. Underpower is killer....you do NOT want to drive your receiver or amp into clipping.
