KEF Q300 Speaker Disassembly |
 |
KEF Q300 2-way Hi-Fi Speaker
Manufactured in China
I sticked a hook on the rim, then I pull out the plastic rim. |
|
 |
 |
You can see some mold on the rim.
This may be due to the high humidity in Hong Kong. Inside my flat, the humidity is always higher than 80%. |
|
 |
The plastic rims that pulled out at the beginning. |
|
 |
The screw is rusted ... ... the Quality Control is ... ... failed |
|
 |
If you would like to upgrade the inner wiring or the Speaker Crossover, you have to uninstall the speaker and this plate. |
|
 |
Go ahead ... ... uninstall the speaker socket ... ...
The crossover is installed at the back ... ... why ??? |
|
 |
Lots of Sound-absorbing cotton |

The manufacturing standard is Pass or Fail ?
I have no idea because this is my first disassembly of a Hi-Fi grade speaker. |

KEF Q300 Crossover |
|
 |
Now, you should know the reason of installing the crossover at the back of the speaker sockets. |
|


|
When you turn the two knobs among the sockets, the metal plates will make contact with the circuit board (Red , Yellow arrows), then you do not have to use the jumpers shown in the photo. |
