Konfiguracja i instalacja
Prawidłowy montaż jest kluczowy dla optymalnej wydajności i bezpieczeństwa. W razie wątpliwości co do któregokolwiek kroku, skonsultuj się z profesjonalnym instalatorem.
- Enclosure Selection: The 508E-D2 is designed for use in a sealed or ported enclosure. Refer to the specifications section for recommended enclosure volumes (0.5 - 1.0 CuFt for ported). Ensure the enclosure is robust and properly sealed.
- Montowanie:
- Cut a mounting hole with a diameter of 7.125 inches (181mm).
- Ensure sufficient mounting depth of 4.875 inches (124mm) is available.
- Secure the subwoofer to the enclosure using appropriate screws, ensuring an airtight seal.
- Okablowanie: The 508E-D2 features a Dual 2-Ohm voice coil. Proper wiring is essential to match your ampwymagania dotyczące impedancji transformatora.
- For a 1-Ohm load (parallel wiring): Connect the positive terminal of voice coil 1 to the positive terminal of voice coil 2. Connect the negative terminal of voice coil 1 to the negative terminal of voice coil 2. Connect the ampdodatnie wyjście prostownika do połączonych zacisków dodatnich i amplifier's negative output to the combined negative terminals.
- For a 4-Ohm load (series wiring): Connect the positive terminal of voice coil 1 to the amplifier's positive output. Connect the negative terminal of voice coil 1 to the positive terminal of voice coil 2. Connect the negative terminal of voice coil 2 to the ampujemne wyjście lifiera.
Ostrożność: Incorrect wiring can damage your subwoofer and amplifier. Always verify impedance before connecting.
- Amplifier Połączenie: Podłącz subwoofer do odpowiedniego amplifier capable of providing 500 Watts RMS at the chosen impedance. Use high-quality speaker wire of appropriate gauge.

Instrukcja obsługi
Once installed, follow these guidelines for optimal operation and to prevent damage.
- Okres docierania: Allow a break-in period of approximately 20-30 hours of moderate listening before operating the subwoofer at high power levels. This allows the suspension components to loosen and perform optimally.
- Ustawienie wzmocnienia: Ustaw swój amplifier's gain correctly. Do not use the gain control as a volume knob. It should be set to match the output voltage of your head unit. Incorrect gain settings can lead to clipping and damage.
- Ustawienia crossovera: Użyj filtra dolnoprzepustowego (LPF) na swoim amplifier or head unit to send only low frequencies to the subwoofer. A typical starting point for an 8-inch subwoofer is 80-100 Hz with a slope of 12dB or 24dB per octave.
- Filtr poddźwiękowy: Jeśli twój amplifier has a subsonic filter (high-pass filter for the subwoofer channel), set it slightly below your enclosure's tuning frequency (for ported enclosures) or around 25-30 Hz (for sealed enclosures) to protect the subwoofer from over-excursion at very low frequencies.
- Regulacja głośności: Always turn on your audio system with the volume at its lowest setting and gradually increase it. Avoid prolonged listening at maximum volume levels, especially if you notice distortion.
Konserwacja
The DD Audio 508E-D2 subwoofer requires minimal maintenance to ensure long-term performance.
- Czyszczenie: Periodically wipe the cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
- Kontrola: Regularly inspect the subwoofer for any signs of damage to the cone, surround, or dust cap. Check wiring connections for tightness and corrosion.
- Czynniki środowiskowe: Protect the subwoofer from extreme temperatures, direct sunlight, and excessive moisture. While robust, these conditions can degrade materials over time.
