Axiom Home Page Forums General Discussion Technical Questions amp power rating @ 8 and 4 ohms

Ignore max suggested amplifier power. It's nonsense, in pretty much all cases. Axiom has tested 'M80s with waaaaaay higher power than 400w.
As far as impedance and amplifier power go, assuming ideal conditions, 4 ohm ratings would be double 8 ohm ratings. But like John said, you're rarely, if ever, going to get close to that max power in real life. If you are, you probably have
A. An extraordinarily large room
B. A need for a larger amp.
C. Hearing damage
