راه اندازی و نصب
نصب صحیح برای عملکرد و ایمنی بهینه بسیار مهم است. اگر در مورد هر مرحلهای مطمئن نیستید، با یک نصاب حرفهای مشورت کنید.
- 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.
- نصب:
- 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.
- سیم کشی: The 508E-D2 features a Dual 2-Ohm voice coil. Proper wiring is essential to match your ampالزامات امپدانس تقویت کننده.
- 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 ampخروجی منفی تقویت کننده.
احتیاط: Incorrect wiring can damage your subwoofer and amplifier. Always verify impedance before connecting.
- Ampاتصال فایر: ساب ووفر را به یک دستگاه مناسب وصل کنید amplifier capable of providing 500 Watts RMS at the chosen impedance. Use high-quality speaker wire of appropriate gauge.

دستورالعمل های عملیاتی
Once installed, follow these guidelines for optimal operation and to prevent damage.
- دوره شکست: 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.
- تنظیم سود: خود را تنظیم کنید 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.
- تنظیمات متقاطع: از یک فیلتر پایین گذر (LPF) روی دستگاه خود استفاده کنید. 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.
- فیلتر سابسونیک: اگر شما 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.
- کنترل صدا: 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.
تعمیر و نگهداری
The DD Audio 508E-D2 subwoofer requires minimal maintenance to ensure long-term performance.
- تمیز کردن: Periodically wipe the cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
