About :
Midrange and loudspeakers are part of audio systems that play the role of sound in the middle and high frequencies. Midranges are generally used to reproduce midrange frequencies, ranging from about 250 Hz to 2000 Hz, while loudspeakers or midranges can also cover frequencies above 2000 Hz. For midrange and speaker repairs, there are a few basic steps that must be followed carefully: 1. **Problem Diagnosis**: First you need to determine exactly where the problem is. Is the sound hissing, the speaker cutting off and on, or no sound at all? 2. **Opening the Speaker**: Using the appropriate tools, open the speaker case. Be careful not to damage the internal parts. 3. **Inspection and cleaning of parts**: Check the internal parts of the speaker such as the coil, diaphragm and magnet and make sure they are clean. Dust or foreign particles can impair the performance of the speaker. 4. **REPLACE DAMAGED PARTS**: If coil or diaphragm are damaged, replace them with new parts. Usually, spare parts for midrange and speakers are available in the market. 5. **Closing the Speaker**: After making repairs and ensuring proper operation, carefully close the speaker frame. 6. **Final Test**: Connect the speaker to the audio system and make sure it works properly. Pay attention to the sound quality and fix the previous problems.
