Hi.

I need help selecting the right upper suspension for my Lexus LS430 speakers - Mark Lewinson Audio.

Due to its age, the factory foam suspension is slowly disintegrating, and I'd like to restore it. Special repair kits are available in the US, but shipping to Poland is a problem. Front Door - ML 86160-0W240
Repair Kit Mount Dimensions:

Outer diameter:
6-1/8" (156mm)
Roll outer diameter:
5-1/2" (140mm)
Cone diameter:
4-3/8" (111mm)
Inner diameter:
4" (102mm)
Foam roll width:
5/8" (16mm)

Rear Door - ML 86160-0W440 LH
Repair Kit Mount Dimensions:

Outer diameter:
4-1/4" (108mm)
Roll outer diameter:
3-7/8" (98mm)
Cone diameter:
3" - 3-1/8" (76mm - 79mm)
Inner diameter:
2-5/8" (67mm)
Foam roll width:
3/8" (10mm)

Regeneration

 

I used these for the front Mark Levinson speakers but any 6"/156mm ones will do.
Maybe try this kit You may need to search on Amazon.pl rather than buying from the UK.

I would be surprised if your rear door speakers need re-foaming as they don't seem to suffer from the problem, but if they do then buy a kit for 4" speakers

 

I also have a problem with the subwoofer speaker in the back. Do you have the dimensions of the repair kit's diaphragm?

 

The Sub needs an 8 inch repair kit.

 

All my speakers were toast...I purchased from eBay the speaker repair kit - Simy FSK-430
