We always fasten the Zobel's resistor and the crossover PCB to the bottom panel. Then we lay fiberglass insulation over them, with slits cut to allow wiring to pass through. The block of components R1/R2/C1 attaches to the crossover PCB and then they lay on the insulation. So the insulation forms a cushion between this block of components and the crossover PCB or the cabinet panels. Same thing for the Zobel capacitor, in that it lays on the insulation and is padded from vibrating against the cabinet.
