Renew your audio: A guide to crossover repair and replacement, and strong support from our factory

In the audio system, the crossover plays a vital role. It is responsible for decomposing the audio signal into different frequency ranges and assigning them to the corresponding speaker units (tweeter, midrange, bass), thereby ensuring that each unit can work within its optimal frequency range to achieve balanced, clear, and high-fidelity sound reproduction.

However, various problems may occur during the use of the crossover, such as:

Component aging or damage: Components such as capacitors, resistors, and inductors will age over time, or be damaged due to overload, moisture, etc., resulting in crossover point shift, frequency response distortion, or even silence.
Circuit board failure: Solder joints on the circuit board may have problems such as cold soldering and cracking, affecting signal transmission.
Overload damage: When a high-power audio system is running at high load for a long time, it may cause the crossover to overheat and be damaged.
How to determine whether the crossover needs to be repaired or replaced?

Here are some common fault phenomena:

The sound is distorted, fuzzy, or harsh.
One or some speaker units are silent or sound abnormal.
The overall sound quality of the audio system has deteriorated.
The crossover has obvious burns or odors.
If you encounter any of the above situations, you should check the crossover in time and repair or replace it if necessary.

Steps for repairing and replacing the crossover:

Disconnect the power supply: Before operation, be sure to disconnect the power supply of the audio system to ensure safety.
Removing the crossover: Carefully remove the back panel of the audio box, find the crossover, and remove it from the box.
Check the components: Carefully check the components on the crossover to find signs of aging, damage or burning.
Replace components: Use professional welding tools to replace damaged components.
Check the circuit board: Check the solder joints on the circuit board. If there are cold solder joints or cracks, re-solder them.
Install the crossover: Install the repaired or replaced crossover back to the audio box.
Test: Connect the audio system and test whether the sound is normal.
