Long haired wool works fine — at least at 1st. it is not moth proof and will sag. If you are going to use it i would suggest a 50/50 mix with polyfill to make it stay in place.

Mundorf angel hair is better, moth proof and without mixing it with polyfill it will stay in place.
Ps: No, I've no financial interest in Mundorf. Just sharing my experience..
Angel hair looks nice and gets good reports… i have a sample somewhere, but it is hard to get ahold of in Canada.

We were sceptical of Angel Hair at first but we've used it in our latest speakers and it works well. No measurements yet but it sounds good. It is easy to use as it expands and is light enough to stay in place without a great deal of further support.

I’ve always favored Acousta-Stuf. It’s been my go-to choice for a long time. Affordable, no itching or nasty stuff getting on your skin or in your lungs. It doesn’t sag and there’s no worries about moths or mold.

Tang Band W5-2143 in 20 liter box. 40 grams of angel hair makes 14,40 USD per box:'$360 USD for a kg! Very pricey stuff.'
Yes, but you don't need much.
Twaron Angel hair works excellent at mid frequencies. A little goes a long way (can clearly be seen in impedance plots). I found fiberglass (the itchy stuff) hard to beat at lower frequencies (in a sealed enclosure, wouldn't want it in a ported solution).
A combination actually worked remarkably well over a large range. So did wool felt on walls with fiberglass fill.

There should be some examples in that huge thread of mine. I'm pretty shure I showed some impedance plots while testing different damping materials.
I'll look for the specific posts a little later today.

Here's a plot, but not with a pure fill of angel hair. I wanted a solution for the entire range I was going to use these drivers in (about 20 to 20 kHz 🙂) so that's where my focus was.
I might have some more data saved somewhere, pretty sure I also tried Angel hair by itself.

Edit: I looked trough the files I saved, sadly no Angel hair solo measurements. I took those measurements on an older laptop and only transferred the plots that satisfied my curiosity at the time. I had about 3 days of testing all kinds of materials and combinations.
I finally opted for a combination of wool felt (real sheep wool) on all walls and fiberglass as fill. Nasty itchy stuff, but a one time deal putting it in a sealed enclosure.

Thanks a lot. Seems angel hair lowers the impedance peak around 180 hz a lot.![]()
