I came across this googling for acoustically transparent fabrics that had a pattern on them. It's a fabric called Xorel and the manufacturer claims it is acoustically transparent but I can't seem to find any acoustic testing information on it. Has anyone used this or tested a sample for transparency?
I haven't looked into the price. I wanted to try to determine if it was actually useable first.
The particular Xorel style I liked was called Damask. That one doesn't appear to be one of the ones listed in their test results. I might see if I can get a sample of it. I could at least do the blow test.
The prices are all listed. There is also a pdf price list download.
The cheapest is about double FR701, and the most expensive over $100/yard. Plus $3 per yard cutting charge??? They only have to cut once. It is ridiculous to have a cut charge per yard at 10% of the total cost.
