The first thing I'd like to do is thank Vinh from Team Toxic Bass for this article.
This article explains step by step how you can repair a damaged ribbon element by using kitchen aluminum foil. Of course you can always contact DiyMobileAudio for ribbon replacements as well. The only difference is that the kitchen foil is a tiny tiny bit thicker. As far as I can tell, there's very little difference. The kitchen foil has perhaps slightly lower sensitivity, but a slightly smoother top end. Feel free to experiment with different size wrinkles, tensioning, and width.
This example uses the LCY 130 tweeter, but more or less all the drivers from AC, Fountek, and LCY can be repaired in a similar fashion.
01: All tools needed. Aluminum Foil, Ruler, Razor, Rippled Bottle Caps. You can also try experimenting with different brands of aluminum foil, copper foil tape, etc. but that's an entirely different topic.
02: Holding sercurely both allen-tool and bolt with both hands, remove
the bolts. (Note: Try not to hold allen-tool or bolt directly over
ribbon cavity / magnetic field)
03: Bolts will be sucked in.
04: Without bringing allen-tool directly over ribbon cavity, unscrew
bolts. Take out allen-bolt and allen-tool, holding them both
05: ..or else.
06: After metal bolts are removed, remove protective tape and plastic
(ribbon) holding blocks.
07: If you cannot measure original ribbon element measure ribbon
cavity for ribbon width.
08: With a ruler, flatten out wrinkles on the piece of aluminum foil,
on a flat surface.
09: Using the ruler and razor, cut one straight side.
10: Measure and mark, with the razor, the width needed for the ribbon.
11: New ribbon element cut to size.
12: Two bottle caps held together for ribbon ripple making.
13: Its all in the technique... feel free to experiement with small and large ripples.
14: Plastic holding blocks are different in size. Make sure you put
them where theyre suppose to go. (Note: Sticky glue on ribbon-side of
15: Placing the new ribbon element in as straight as possible. Place
the plastic holding block in as straight as possible (Note: Glue on
plastic holding block will prevent you from moving/twisting straight
once it is pressed down onto the ribbon - without twisting the ribbon
element). Holding allen-bolt sercurely, place inside hole. Then
holding allen-tool sercurely, screw in allen-bolt.
16: HOLD YOUR TOOLS (AND BOLTS) SERCURELY!!!
17: New ribbons in. Feel free to experiment with the tension of the ribbons between the blocks... either loosening them with a bit of sag or stretching them tight. If you just want to repair the ribbon, set the ribbon between the blocks identical to the stock ribbon.
18: Cut off excess ribbon element.
19: Place protective tape back on.
20: Holden bolts and tools sercurely, reassemble ribbon tweeter.
