[quote user="chartz"] It would be wonderful if someone would re-manufacture alu strips... [/quote] We should look for a alum. strip that has about the same thickness and width. Then I could let them laser engraved for the text.

Same guy? The invisible one who pops up once in a while

Got one from a dear friend who's a well known member

[quote user="GTS"] Those having refoamed their own - did you shim? I'm headed that way... [/quote] No I did not and never will at leat not for these type of drivers. I will consider using the batterie method for the next refoaming job, but cutting out the dustcaps, no way. Looks yours has been done by a boatworker with two left feet! Just

[quote user="kallasr"]Look for 75 300 ohm fm on ebay.de Ralf [/quote] Ralf, du bist ja fabelhaft, danke! 8 euro each... But no ordering allowed from their neighbours

[quote user="hemenex"] Jacques, so you do have some already? It's a good idea to go to a local radio/TV shop (if there's still one) and ask there. I know such a shop here; at least I got this: I can tell you it fits into a 70's BM5000... And yes I agree eb*y, conrad etc are of no use in this matter. Gunther [/quote] I need one

Btw, I did 4 pairs Penta's (32 midrangers) and they all sound great! Not to mention all the CX's....

I wonder why I don't read anything about shimming methods on Audiofriends and Goodhifi's website and maybe others as well. Have been watching a video on Youtube to see what shimming cones exactly means! Very interesting for these large drivers, still I'm not convinced using this method on small drivers like CX50/100's, Penta's midrangers

[quote user="jfrancis"] Realize that the metal strip has a pretty strong glue securing it to the plastic and you will most like cause some bends in the strip. This is even if you are only bending it enough from each end to expose the screws. So I wouldn't remove the complete strip at all. If you look carefully you can see the bends in

You need to remove part of the aluminium strip at both sides. Behind that there are 2 screws. Be carefull though, the plastic cover at that area can easily break.
