The fabric may sag or wrinkle over time, it certainly did with my tuning panels. Furutech did not help me at all..
An email exchange with Furutech
Me: I bought a pair of RWL-1 tuning panels five years ago and have the original boxes/packing. Over time the silk material has wrinkled and sagged (I suppose gravity is doing its thing). Can you repair this cosmetic flaw somehow or replace the panels for me? They're unusable as is, I'd be happy to email you pictures.
Furutech:
I am sorry to hear of the problem you are experiencing with the room tuning panels. If possible, please email us and image of the sagging silk cover, so we can have a better understanding of the problem.
Me: Thanks for the quick reply, attached please find a picture..
Furutech:
I am afraid not much can be done about these wrinkles. It is a special silk, so applying water would only make it worse. However the effectiveness of the panel with not be diminished by the wrinkles in the silk.
Me: I agree with you, I wouldnt try to use water or steam on them. The panels obviously add value in my sound, however looking the way they do now I cannot use them. Given the price of these panels, and Furutechs reputation for first class products I thought you would repair them, or if thats not possible, replace them. Please advise, and thank you.
Furutech:
The wall panels are a discontinued item and Furutech no longer carries stock, but it may be possible to repair the two panels. Unfortunately, as the product is no longer covered by Furutechs one year manufacturers warranty, they would need to be returned to Tokyo at your expense and repair costs charged. Shipping costs for 1 set (2pcs) would be JPY59,450≒USD735 from Oregon USA to Tokyo and repair cost would be advised after the repair is complete. Please let me know if you would like to proceed
Me: That is certainly not what I expected from a premium manufacturer such as Furutech. The only practical solution at this point is to fix them myself; can you provide some instructions/guidance on how to go about repairing the panels?
