4.1 Zahteve glede ohišja

The G7 8.4 is designed for custom box mounting. Ensure the enclosure is properly sealed and braced to prevent air leaks and vibrations. Consult with an audio professional or use a reputable enclosure design software to determine the optimal volume and port tuning (if applicable) for your specific application.

4.2 Žične povezave

This subwoofer features a 4 Ω Dual Voice Coil (DVC) design. Proper wiring is essential to match the impedance requirements of your amprešilec. Glejte svojega amplifier's manual for compatible impedance loads. Common wiring configurations for DVC subwoofers include:

• Serijsko ožičenje: 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 increases the total impedance (e.g., two 4 Ω coils in series result in 8 Ω).
• Vzporedno ožičenje: Connect both positive terminals together and both negative terminals together. These combined terminals then connect to the amplifier. This configuration decreases the total impedance (e.g., two 4 Ω coils in parallel result in 2 Ω).

Always use appropriate gauge speaker wire for your power levels to minimize power loss and ensure safe operation. Secure all connections firmly to prevent shorts or loose contacts.

5. Navodila za uporabo

Once installed, proper operation ensures the best sound quality and extends the life of your subwoofer.

5.1 Amplifier nastavitve

Nastavite svoj amplifier's gain (level) control correctly. Start with the gain at its minimum setting and slowly increase it until you hear distortion, then back off slightly. Avoid setting the gain too high, as this can lead to clipping and damage to the subwoofer.

5.2 Nastavitve križanja

Izkoristite svoje amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical crossover point for an 8-inch subwoofer might be between 80 Hz and 120 Hz, but this can vary based on your vehicle's acoustics and personal preference.

5.3 Obdobje uvajanja

Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its limits. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance.

6. Vzdrževanje

The DB Drive G7 8.4 Subwoofer requires minimal maintenance to ensure long-term performance.

• Čiščenje: Periodically wipe the subwoofer cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
• Pregled: Regularly check the speaker terminals for secure connections. Inspect the surround and cone for any signs of damage or tears.
• Okolje: Ensure the subwoofer is installed in a location protected from extreme temperatures, direct sunlight, and moisture.
