Use a soldering iron and desoldering pump to remove the old components. Solder the new film capacitors in their place. Film capacitors are larger than electrolytics, so you may need to secure them to the board using hot glue or zip ties. 4. Troubleshooting a Dead Tweeter

The real villain, however, was hiding inside the crossover network board. Elias heated up his soldering iron. He popped off the old electrolytic capacitors. Over twenty years, the electrolyte had dried out, causing the capacitance value to drift.

A healthy driver should read between 4.5 to 5.5 Ohms. If the meter reads "OL" (Open Loop) or infinity, the voice coil is blown. You will need to source a replacement diaphragm or send the tweeter to a vintage audio repair specialist for a voice coil rewind. Conclusion

Unscrew the fuse cap. If the internal wire is broken, replace it with the exact same amperage fuse rated by Cerwin-Vega (typically a 2.5A or 3A fast-blow fuse). Never bypass the fuse with aluminum foil, or you risk destroying the drivers next time.

Carefully scrape away the old sticky foam from the basket frame and the outer edge of the cone using a utility knife, isopropyl alcohol, and scraping tools. The surfaces must be completely clean and dry.

Unscrew the mounting screws securing the 10-inch woofer to the cabinet. Carefully lift the driver out and label the positive (+) and negative (-) wires before disconnecting them.

The original poly-ether foam surrounds deteriorate over 15 to 20 years, turning into a sticky, crumbly residue that ruins bass response and threatens to warp the voice coil. Sensitivity : 95 dB (1W/1m)

Allow the glue to cure completely for 24 hours before reinstalling the woofer into the cabinet. Fix #2: Cleaning the Attenuation Controls (Potentiometers)

Apply a thin bead of speaker repair adhesive to the inner lip of the new foam surround and attach it to the speaker cone. Let it cure. Next, apply glue to the outer lip of the foam and press it firmly against the metal basket, ensuring the cone moves up and down freely without any scraping sounds.
