Configuració i instal·lació

Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Si no esteu segurs de cap dels passos a seguir, consulteu un instal·lador professional.

  1. 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.
  2. Muntatge:
    • 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.
  3. Cablejat: The 508E-D2 features a Dual 2-Ohm voice coil. Proper wiring is essential to match your amprequisits d'impedància del transformador.
    • 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 amplifier's positive output to the combined positive terminals and the 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 ampsortida negativa del lificador.

    Precaució: Incorrect wiring can damage your subwoofer and amplifier. Always verify impedance before connecting.

  4. AmpConnexió del lifier: Connecteu el subwoofer a un dispositiu adequat amplifier capable of providing 500 Watts RMS at the chosen impedance. Use high-quality speaker wire of appropriate gauge.

Instruccions de funcionament

Once installed, follow these guidelines for optimal operation and to prevent damage.

  1. Període d'entrada: 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.
  2. Configuració de guany: Estableix el teu 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.
  3. Configuració de crossover: Feu servir un filtre de pas baix (LPF) al vostre 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.
  4. Filtre subsònic: Si el teu 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.
  5. Control de volum: 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.

Manteniment

The DD Audio 508E-D2 subwoofer requires minimal maintenance to ensure long-term performance.
