I vaguely recall that for models earlier than a certain year (i'm going to throw out 2004 but i could be wrong) that you would need to call Axiom to fix a value.

I remember the relative value of our whole 5.1 system when we purchased it, but i would have to dig way back through paper or possibly a confirmation email to find out the exact pricing we had in 2002.
