설정 및 설치
최적의 성능과 안전을 위해서는 올바른 설치가 필수적입니다. 설치 단계에 대해 잘 모르시겠다면 전문 설치 기사에게 문의하세요.
- 케이스 선택: 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.
- 설치:
- 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.
- 배선: The 508E-D2 features a Dual 2-Ohm voice coil. Proper wiring is essential to match your amp리파이어의 임피던스 요구 사항.
- 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 amp증폭기의 음극 출력.
주의: Incorrect wiring can damage your subwoofer and amplifier. Always verify impedance before connecting.
- Amplifier 연결: 서브우퍼를 적합한 스피커에 연결 amplifier capable of providing 500 Watts RMS at the chosen impedance. Use high-quality speaker wire of appropriate gauge.

작동 지침
Once installed, follow these guidelines for optimal operation and to prevent damage.
- 침입 기간: 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.
- 이득 설정: 설정하세요 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.
- 크로스오버 설정: 저역 통과 필터(LPF)를 사용하세요 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.
- 아음속 필터: 만약 당신의 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.
- 볼륨 조절: 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.
유지
The DD Audio 508E-D2 subwoofer requires minimal maintenance to ensure long-term performance.
- 청소: 콘과 주변부를 주기적으로 부드럽고 마른 천으로 닦아 먼지와 이물질을 제거하십시오. 강한 화학 약품이나 과도한 습기는 사용하지 마십시오.
- 점검: 서브우퍼의 콘, 서라운드 또는 더스트 캡에 손상 흔적이 있는지 정기적으로 점검하십시오. 배선 연결부가 단단히 고정되었는지, 부식이 있는지 확인하십시오.
- 환경적 요인: Protect the subwoofer from extreme temperatures, direct sunlight, and excessive moisture. While robust, these conditions can degrade materials over time.
