John (jakeman), in the comparative chart for the various Axiom subs, the 3 dB sequential difference from EP400 to 500 and 600 appers to be in max sound pressure level. That 3 dB difference does not seem to be the difference in "audio signal level", which would indeed imply doubling of the SPL. If the SPL is not doubled, why would we assume twice the acoustical energy going from one sub to one higher in the sequence? I am not trying to dispute your point, just trying to understand your reasoning and the chart. Thanks.
John
PS: is there yet a 4th John who would like to join in this discussion?
