Rather a moot point for me now as I went out and purchased an external power amp.

Did I need one.. I cannot say.

My thought is that using those online calculators either proves that Axiom is totally falsifying the requirements on their specifications web page, or the calculations are all wrong. An average conversation with someone is around the 60db level. Over 80db caused perminant damage to your hearing. using the link provided, if I wanted 70db of sound 4m away from my M80 speakers, i would need 1db of amplification. But Axiom publishes the speaker minumum is 10db. So to meet Axioms requirement, I will be forced to endure 83db of sound that is like listening to a bulldozer.
