Is your subwoofer no longer playing or not working properly? Contemplating on buying a new one? Why buy new a subwoofer when you can repair your old subwoofer for a fraction of the cost? The most common part of  a subwoofer to go out is the voice coil. In most cases this occurs when applying to much power to the subwoofer(s) and causes the voice coil(s) to “burn”. This can be the result of  incorrect gain settings or improperly wired subwoofers, which can cause a low impedance load on the amplifier. 

Our 2″ dual 4 ohm voice coil is 4 layer wire coil wound on a black anodized aluminum former for superior heat dissipation. Made in the USA and is wound using high temperature adhesive capable of withstanding operating temperatures upwards of 500°F. This attribute has led customers to turn to us when competitors’ coils have come apart due to adhesive failure from low quality voice coils from overseas.

In order to properly fix your subwoofer you need to make sure you use the proper glue. When gluing the voice coil to spider and cone we recommend using our black rubber CA glue. For gluing the surround lip to the frame we recommend using use our L3045 black rubber glue. Same goes as well for gluing dust caps and dressing leads. 

One very important thing to note is that when fixing or building subwoofer(s) using a aluminum voice coil you must us proper soldering flux specifically made for aluminum wire. We offer the soldering flux kit (Ultra Gold Flux) which comes with the proper solder.
