No I did not carry an SPL meter with me to the audition at the Home Theater. The volumes were = since this is a strict A vs B vs C test. They have a very good switcher at the Home Theater store.

I did call the Axiom and they recommended the M60 instead of M80 due to my receiver Onkyo 805.

Will the 2 tweeter on the M80 vs the one on M60 provides better/clearer treble?

Also did some research on Dynaudio, several posting have given rave reviews on their soft dome tweeter.

I am really not bashing the M22. For the price point they cannot be beat. I am happy the mid and low range. Dynaudio is better at the treble level (but note this is not night vs day). The physical appearance of the M22 is much more appealling (the cherry gloss finish matches my decor very well).
