1. Check the container for leaks
The sound leakage will be caused by poor bonding between the box plates, rough processing of the countersink surface of the box, uneven tilt, or no washer placed on the junction box, speaker unit and countersink surface of the box. Find the method, you can use a piece of tissue paper on the box frame, junction box, speaker and box joints, etc., when the speaker is working, if the tissue paper is found to be blown, it indicates that there is a leak. If the joint of the box is leaking, the inside can be coated with adhesive. If the leakage is in the junction box, the speaker and the box joint, the countersunk hole surface should be smoothed and padded with the appropriate thickness of rubber.
2. The bass is soft, lacking power and somewhat cloudy.
< br >
This may be caused by the speaker in the over-damped state, appropriately increase the sound absorption material in the box, or appropriately shorten the length of the inverting hole.

3. Lack of vitality, bass can't come out
< br >
The sound absorption material can be reduced, the length of the inverter can be lengthened appropriately, or the appropriate amount of sand can be injected into the box.

4. The sound is too loud and sounds unnatural
< br >
It may be that the sensitivity of the medium or high frequency unit is too high, making the speaker sound noisy. In this way, some attenuation resistance and other methods can be added to the corresponding cell frequency division network. If the low and high frequency units are felt to sound separately, especially if the sound is felt to jump between the two units near the frequency division point, it may be that the polarity of the speaker unit is reversed.
