Crossover Networks: We inspected and measured crossover components and replaced out-of-spec capacitors.

Internal Wiring: We checked internal connections and speaker wiring.

Speaker Terminals: We inspected and cleaned the rear connection terminals.

Cabinet Restoration: We repaired damaged cabinet surfaces, sanded the finishes, and refinished the wood-veneer exteriors.

Cabinet Cleaning: We removed accumulated dust and cleaned accessible cabinet surfaces.

Driver Mounting: We checked driver mounting hardware and cabinet seals.

Grille Inspection: We inspected the protective grilles and their mounting arrangement.

After Restoration / Final Testing

We completed the speaker burn-in procedure to check performance and stability.

We conducted frequency-sweep testing and listening evaluations on each speaker.

We checked the speaker assemblies for normal sound output following service.
