My first thought would be that the two speakers probably have different placement requirements; the Energy speakers would have been carefully placed by the store while the M80s were brought in for the test.

We're only guessing though without a few clues re: what you didn't like about the Axioms, ie what differences you saw between the two speakers.

I'm guessing that the Energys have more like "the M50 sound" than "the M80 sound", ie they will probably sound "smoother" than the 80s due to a slight midrange dip. I couldn't find graphs for C-7 but the C-3 and C-9 definitely show a response more like the M50 than the M60/M80.

Anyways, if you can give us a bit more detail re: what differences you heard we can probably be more helpful...
