3.3 Cableado e conexións

The GZHW 20XSPL features a dual voice coil design with an impedance of 2 x 1 Ohm or 2 x 2 ohms. Proper wiring is essential to match your amplifier's capabilities and achieve the desired impedance. Refer to your ampManual do adaptador para cargas de impedancia compatibles.

• Parallel Wiring (0.5 Ohm or 1 Ohm total): Connect positive terminals of both voice coils together, and negative terminals of both voice coils together. Then connect to the amplifier. This configuration results in a lower impedance.
• Series Wiring (2 Ohm or 4 Ohm total): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals connect to the amplifier. This configuration results in a higher impedance.

Always use high-quality speaker wire of appropriate gauge for the power levels involved. Ensure all connections are tight and free from corrosion.

4. Instrucións de funcionamento

Once installed, the GZHW 20XSPL subwoofer operates as part of your audio system. Its performance is dependent on the amplifier and audio source it is connected to.

4.1 Manexo de enerxía

The subwoofer has a recommended power handling of 300-1500 W, with an RMS power of 700 W and a peak power of 1500 W. It is crucial to match the amplifier's output to these specifications to prevent damage. Underpowering can be as damaging as overpowering, as it can lead to amplifier clipping, which produces distorted signals harmful to the subwoofer.

4.2 Período de rodaxe

Allow a break-in period of approximately 20-30 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance, improving overall performance and longevity.

4.3 Configuración de audio

Adjust the low-pass filter (LPF) on your amplifier or head unit to properly integrate the subwoofer with your main speakers. A typical LPF setting for subwoofers is between 60 Hz and 100 Hz. Experiment with phase settings (0° or 180°) to achieve the best blend with your other speakers.

5. Mantemento

The Ground Zero GZHW 20XSPL subwoofer requires minimal maintenance to ensure its longevity.

• Limpeza: Usa un pano suave e seco para limpar o cono e o seu contorno. Evita o uso de produtos químicos agresivos ou produtos de limpeza abrasivos.
• Inspección: Periodically check the speaker terminals for secure connections and signs of corrosion. Inspect the surround for any cracks or tears.
• Ambiente: Keep the subwoofer in a dry environment, away from direct sunlight and extreme temperatures. While not waterproof, it is designed for robust use within typical vehicle or home environments.
