Foam Surround Replacement
The most common issue with vintage speakers is "foam rot." The flexible edge around the cone disintegrates over 15-20 years. We meticulously clean the frame and cone, then install premium UV-resistant foam surrounds using specialized adhesives.

- Prevents voice coil damage
- Available for almost all brands (JBL, Advent, Bose, Infinity, etc.)
Crossover Rebuilding
Electrolytic capacitors in your crossover network dry out over decades, causing muddy sound or lost treble. We "recap" crossovers using audiophile-grade film capacitors to bring back transparency and detail.
- High-grade Polypropylene capacitors
- Resistor inspection and replacement
- Internal wiring upgrades available
Diagnostics & Voice Coil Repair
Scratchy sound? No sound at all? We use signal generators and impedance sweeps to locate voice coil rubs, open circuits, or tinsel lead fractures. If a driver is blown, we can often source exact replacements or recone kits.
- Detailed bench testing
- Re-magnetizing (if needed)
- Tinsel lead repair
