Not sure if you’ve tried this or not but....Might be good to swap the speakers from left to right and rule out the amplifier or pre. It would confirm it’s the speaker / woofer if the issue travels. Then at least you know that much before making the trip to axiom.

Edit: I just re read the post. Seems the cerwin Vegas worked properly with amplifier. Might still be good to swap channels though and just see what you get.
