Do you have a picture Danny.

I do have some measurements that show difference, bu tAFAIC it is open to interpretation.

I strongly sispect that what you measured is not what EnABL does.

It has been a while but there was a whole thread on it: https://www.audiocircle.com/index.php?topic=59575.msg530093#msg530093

I found zero difference measured in any way. I still have the woofers sitting around in here too.

The dots or dashes did little more than color the cone. There was not enough mass there to do anything and while the pattern looked cool it was not where any real cone damping needed to be.

There is also FAR greater differences in compliance and damping from burning the driver in than what effect any of this might have.

Danny, you really should try silicone fluid doping of FR drivers just once to see what you thinks...

I used to get my silicone fluid (or oil) from Ambersil, but they don't stock it any more. 5 minutes googling finds these guys in the UK, and i'd be astonished if it wasn't as easy to find in Texas. http://www.allcocks.co.uk/en/products/silicones/fluids.htm

It's completely non toxic, does not harm the environment, and does not cause degradation over time. I found 60 cSt (centistokes) worked well for my soft FR paper cones, but try higher viscosities. I treated some drivers recently: just put drivers on table, paint silicone fluid on cone nice and thick, let soak into the fibres overnight then turn driver upside down and drain. Even though the silicone fluid soaks in, I normally coat both sides to be thorough. The drivers weep for about a week if you fit them immediately but it causes no harm to veneer or electronics and just wipes off. Take a waterfall plot before and after and you'll see what I mean about smoother response...
