3″ Dual 2 Ohm CCA Black Voice Coil 2.91″ WW

3″ dual 2 ohm voice coil features a 4-layer copper-clad aluminum (CCA) wire. It is wound on a black anodized aluminum former specifically designed to enhance heat dissipation during high-power operation. The black anodized aluminum former plays a crucial role in improving thermal conductivity. This helps prevent overheating and increases the voice coil’s durability and resistance to corrosion over time.

By incorporating copper-clad aluminum wire, the voice coil benefits from an optimized balance of conductivity, reduced weight, and cost efficiency. This makes it a high-performance option for demanding audio applications. The unique combination of a copper outer layer and an aluminum core allows the wire to deliver excellent conductivity. It also lowers the overall mass compared to a voice coil made from pure copper. This reduced mass improves efficiency and responsiveness. It enables faster and more precise movement, which contributes to superior transient response, enhanced clarity, and better performance overall.

The copper cladding in copper-clad aluminum (CCA) wire plays a critical role in minimizing power loss. It enhances electrical conductivity and ensures efficient energy transfer to the speaker. This ultimately results in cleaner, more dynamic, and distortion-free sound output. In addition to excellent conductivity, CCA wire has enough strength to endure high temperatures and mechanical stress. These stresses are typically experienced during high-power audio applications. The copper layer surrounding the aluminum core also improves electrical performance. It simplifies the soldering process, making it easier to create secure connections and integrate the wire into various designs.

By optimizing the balance between conductivity, tensile strength, and low weight, the CCA voice coil improves speaker movement control. It also enhances stability and thermal handling under demanding conditions. These combined benefits lead to accurate sound reproduction, increased durability, and reduced distortion. This makes it an excellent choice for users seeking high-performance output without sacrificing system efficiency or reliability.

This voice coil utilizes a high-temperature adhesive that withstands up to 500°F. This superior construction has earned customer trust. It performs reliably compared to competitors’ coils that fail due to poor-quality adhesives from overseas.

Adhesives for Subwoofer Repair and Reliability

To ensure long-lasting reliability, this voice coil is constructed using a high-temperature adhesive capable of withstanding extreme temperatures up to 500°F. As a result, it performs well under demanding conditions and has earned customer trust. By contrast, competitors’ coils often fail due to inferior adhesives.

When repairing a subwoofer, it’s essential to use the correct adhesive for each component to ensure proper bonding:

Voice Coil to Spider and Cone: Black rubber CA glue provides a strong, flexible bond for these critical connections.
Surround Lip to Frame: Use L3890 black rubber glue, which maintains flexibility to handle the inherent vibrations in subwoofer operation.
Dust Caps and Lead Wires: Likewise, L3890 glue is ideal for securing dust caps and dressing lead wires, ensuring they remain securely in place during use.

Using adhesives formulated specifically for speaker repair is crucial. They are designed to withstand the unique stresses and vibrations experienced by subwoofer components. Therefore, always follow the manufacturer’s guidelines to ensure optimal performance and longevity.

Soldering Aluminum Voice Coil Wires

Soldering aluminum voice coil wires can be challenging due to aluminum’s natural oxide layer, which hinders standard soldering methods. Thus, to achieve a reliable bond, it’s essential to use both a flux and solder specifically designed for aluminum.

For best results, we recommend our Ultra Gold Flux Soldering Kit, which is formulated to effectively disrupt the oxide layer and facilitate a strong connection between aluminum components. Otherwise, attempting to solder without these specialized materials may result in weak joints or even complete connection failure. Therefore, investing in the appropriate soldering kit is essential for ensuring the durability and performance of aluminum voice coil repairs.
