Get yourself a set of allen wrenches. First, you would need to remove bottom strut (plastic part that holds panel to woofer enclosure). This will let you slide down woofer grille. Than you have woofer nicely exposed an quite a few (4mm?) hex bolts to remove. Unplugging red and black wires from driver terminals its tricky as the small wire connectors have a latching pin, which you will have to pull out slightly. Assuming driver for Vantage are the same as for Vistas, cost was about $80 each plus shipping.
You can get detailed instructions from ML.
Just a few warnings:
- do not overtight larger allen screws on bottom strut. Plastic may crack....
- lay speaker flat with panel facing up an SUPPORT panel top end with something to not to put strain on other plastic elements.
