Guillermo,
Just checking to see if you found a solution to your problem. I am a new Axiom owner and love the speakers, however I'm experiencing the exact same problems now that you describe with the EP175. I have to turn the volume up high in order for the sub to wake up. Just curious what receiver you are using? I'm using the Pioneer 912, in case it might be the cause of the problem.
I've checked everything mentioned in this thread if anyone else has an idea let me know.
P.S. Thanks for the great service Marc.
Jason
