4. පිහිටුවීම
Proper installation is crucial for the performance of your speaker driver. Follow these steps carefully:
- Enclosure Preparation: Design or select an appropriate speaker enclosure (box) with an internal volume of approximately 6.5 liters, as indicated by the equivalent volume (Vas) specification. Ensure the speaker opening diameter is 120mm.
- සවි කිරීම: Secure the speaker driver into the prepared opening using screws. The screw diagonal hole spacing is 140mm. Ensure a tight seal between the speaker frame and the enclosure to prevent air leaks, which can negatively impact bass response.
- රැහැන් ඇදීම: ස්පීකර් පර්යන්ත ඔබේ amplifier or crossover network. The speaker has two terminals, typically marked for positive (+) and negative (-). Ensure correct polarity to avoid phase issues in your audio system. This speaker supports audio line communication.
- Crossover Integration: As this is a subwoofer/woofer, it is designed for low-frequency reproduction. It is recommended to use an appropriate crossover network to filter out higher frequencies, directing only the bass signals to this driver. The speaker is designed for a two-way audio crossover system.
5. මෙහෙයුම් උපදෙස්
Once installed, operate your speaker driver as part of your complete audio system:
- බල ගැන්වීම: ඔබගේ සක්රිය කරන්න amplifier සහ ශ්රව්ය මූලාශ්රය.
- ශබ්ද පාලනය: Start with a low volume level and gradually increase it to your desired listening level. Avoid excessively high volumes that cause audible distortion, as this can damage the speaker.
- විවේක කාලය: New speaker drivers often benefit from a 'break-in' period. Play music at moderate volumes for several hours to allow the suspension components to loosen up, which can improve sound quality.
- පද්ධති ඒකාබද්ධ කිරීම: ප්රශස්ත කාර්ය සාධනය සඳහා, ඔබේ amplifier's output impedance matches the speaker's impedance (4 Ohm or 8 Ohm). If using a dedicated subwoofer amplifier, adjust its gain and crossover frequency settings to blend seamlessly with your main speakers.
6. නඩත්තු කිරීම
To ensure the longevity and performance of your speaker driver, follow these maintenance guidelines:
- පිරිසිදු කිරීම: කෝන් එක මෘදු ලෙස පිස දමා දූවිලි ඉවත් කිරීම සඳහා මෘදු වියළි රෙද්දකින් වට කරන්න. රළු රසායනික ද්රව්ය හෝ අධික තෙතමනය භාවිතා කිරීමෙන් වළකින්න.
- පාරිසරික තත්ත්වයන්: Keep the speaker in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.

8 පරිශීලක ඉඟි
- RMS බලය: While the peak power is 120W, the rated power (RMS) is 20-40W. It's best to match your amplifier's output to the rated power for sustained, clean audio without risking damage.
- බාස් කාර්ය සාධනය: This speaker is noted for good bass reproduction, particularly for music genres like organ music. However, for very dynamic and demanding low-frequency content, such as heavy drum beats, it might not provide the deepest excursion. It is primarily designed for home audio, not high-SPL concert or car audio applications.
- Low-Frequency Focus: The speaker excels at low frequencies, especially around 60Hz. Ensure your audio system's crossover is set to leverage this characteristic for optimal sound.
- සංවෘත නිර්මාණය: The quality of your speaker enclosure significantly impacts the performance of this driver. A well-designed and sealed enclosure is crucial for achieving tight and impactful bass.
