I e-mailed Axiom on this topic. Here is my e-mail

Hello,

When measuring the front mains for positioning do you measure from the
back of the speaker cabinet or from the center of the front of the
speaker. I know it is said to have unequal distances from the back and
side walls but it will certainly vary if there is no set rule on where
this measurement is taken.

Here is their response

Hi Rick,

Measure from the back of the speaker.
