قدرت هندلینگ
The G12M Greenback has a power handling capacity of 25 Watts. It can be used singly in low-powered amplifiers or in multiples for higher-powered rock heads. Always ensure the total power output of your amplifier does not exceed the combined power handling of your speakers.
تعمیر و نگهداری
The Celestion G12M Greenback is a robust speaker, but proper care will ensure its longevity and consistent performance.
- تمیز کردن: Use a soft, dry cloth to wipe down the speaker frame and cone. Avoid using liquid cleaners or solvents, as these can damage the cone material.
- ذخیره سازی: If storing the speaker for an extended period, keep it in a dry, temperature-controlled environment, ideally in its original packaging, to protect it from dust and physical damage.
- بازرسی: Periodically inspect the speaker for any signs of damage, such as tears in the cone, loose connections, or bent frame. Address any issues promptly.
عیب یابی
If you experience issues with your Celestion G12M Greenback speaker, consider the following common troubleshooting steps:
| مشکل | علت احتمالی | راه حل |
