Hi Ken,

For any of the models with the separate chamber for the 5.25" woofer like the M60, M80, M100, and all the LFR Series it does involve soldering because the wires going to the internal chamber need to be removed on the crossover board (there is no way to get your hand up to that internal cabinet). You are going to want to have dainty hands to get at the bolts that hold the crossover board to the cabinet too. So my suggestion would be to not attempt it.
