If it was that simple, just a dissipative coating in the range of 10^8 or 10^9. Hahaha.
Every coating has a different sound and reacts different to HV. Lasting for...... Sticking.....
Tested several hundred different coatings over a period of 8 years. There are very very few that have all the required features and sound good.
Factory treated film? With coating already applied? Not an option IMHO. Clear non treated film requires already buying in very large quantities. Think 25-50 km per batch.
Thickness of less importance. Hahaha. Specially for high frequencies thickness counts. Again just my opinion.
My only experience is with Quads, nothing else.
ER audio , Sanders etc are quite rare in my country. So never had the oppurtunity to compare them with audiostatics. Many of the audiostatics are quite narrow so they lack low midbass energy. I use them with a sub. Although the sub doesnt fill in this midbass suckout, the subjective perception is a speaker with much improved bass.
I got out my tape measure.
On my MG1.6s, the left speaker has tuning dots at 8, 19, and 28 inches from the top. The right speaker has tuning dots at 8, 19, and 31 inches.

Hi,
films .... unfortunately the availabilty drops and prises shot up.
While one could get a ´rest´ on a roll -probabely about 20km- a couple of years ago for ~200€, the actual prices for such rest-on a-roll quantities approaches easily 600€ .... and hardly anything below 6µm thickness. Maybe a nice offer at the time .... 7µm plasma pretreated

I had to check one of my pairs of 1.6. You're right !
On my 3.7's ... same location of the "dots" on both speakers.
Interesting!
One would think the need to distribute the resonances exists at all panel sizes.

This thread was about bass panels right?
At lower frequencies it is vital that the surface resistance is higher than 10^8 ohms to reduce distortion.
25um is perfectly fine at a frequenzy <200 hz. Remember that at this frequency and high excursion it is not the mass of the membrane that is dominant! It is the air itself. At higher thicknesses you dont need PET film, you have many many different plastic films to choose from to get sufficient strength.
All this should make it more easy to find a good option. In worst case we can add a coating afterwards but a pretreated film would be very nice.

No problem to find below 6 mu, as low as 2 mu, but you forgot a 1 in front of the 600 😳
