Hmmm, I wonder if this is the glue problem. Over time, the glue that adheres the wires to the panel can degrade and cause detachment. Rough handling during the move could've contributed.
Magnepan could surely take the speakers in for a checkup or re-wiring, but that'll cost. Do the less expensive stuff first: Check the fuses and jumpers. Not sure about the 2.7s, but if you remove the 1ohm resistor, it MUST be replaced with a jumper, usually the included steel-nickel U-shaped jumper.
