Hi KolfMAKER, was hoping to find it for you in the service manual: only the screw specs are given. Login to view image Login to view image The screws in the photograph appear much longer than the 32.7. Also, just two washers seem to be used. Hopefully someone can measure the springs for you.

Thnx @Tignum, this is helpful! I think the width of the allen screw is compliant to M4. I found a screw with a fitting thread, which has a 4mm diameter. The length of (1) I think is correct. If I measure with a fitting screw, it goes into the speaker for about 1cm. So there should be 22.7mm sticking out to hold the bracket and have space for the washers and the spring. The bracket thickness is 4mm, each washer is 1mm, so that takes 6mm. The spring then sits in a space of 16.7mm, actually a bit less when put under pressure. So I assume the spring in an unstring condition could be like 18-20mm. I will now start looking for those parts.`

Hi, with you finding M4 thread, the 6 in 6 x 32.7mm must then be the diameter of the head of the screw.

Perfect, thanks!
