Soundqubed HDX3 3″ Dual 1 Ohm Voice Coil

Soundqubed HDX3 3″ Dual 1 Ohm Voice Coil

Our  Soundqubed HDX3 3″ dual 1 ohm voice coil features a 4-layer copper round wire, wound on a high-temperature black anodized aluminum former. The former efficiently dissipates heat during demanding operation, while the anodized finish enhances thermal conductivity and resists corrosion over time. This construction ensures reliable, consistent performance under high-wattage, high-temperature conditions, making it an excellent choice for high-performance subwoofers.

Additionally, copper wire offers excellent electrical conductivity, superior to that of aluminum, enabling efficient power transfer with minimal signal loss. While copper is denser and heavier than aluminum, its higher conductivity improves overall system efficiency, especially in applications demanding precise, controlled audio reproduction. The increased mass of the copper windings also enhances low-frequency control and dampening, resulting in deeper, tighter bass response with reduced distortion.

Using a round wire format provides dependable winding integrity and durability. Though round wire occupies slightly more space than flat wire, it offers increased mechanical strength and reliability under continuous high-power operation. This helps prevent coil deformation, ensuring the voice coil maintains structural integrity and consistent performance over time.

This voice coil utilizes a high-temperature adhesive that withstands temperatures up to 500°F. This superior construction has earned customer trust, especially when 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.
