I'm trying to use this SPL Calculator to get a better idea of how many watts I'm really using to achieve the SPL dB's I'm seeing when the Emotiva amps go into protective mode.

This calculator takes into account speaker placement in relationship to the walls, as well as if your using 1 or more speakers during the measurements.

The question I have is that it appears to be for an 8ohm speaker? So, how do I interpret the results when considering my m80's?

Based on what I'm figuring so far, there is no way I'm maxing out this amp?
