EnABL Pattern and Ribbed Cones
Do reenforcing ribs reflect enough energy to interfere with the effect of the EnABL treatment?

Brian,
Microphone diaphrams, headphone diaphrams ,dome tweeters, all have to have the pattern applied with a technical pen i.e. Kohinoor or Mars. These are becomming a little difficult to find in all towns. A 50% mixture of Poly S and water should be mixed in the ink storage tank of the pen and a lot of time spent convincing it to flow. Once that part is done they work very well, even on ear buds. For all of you who are interested, the best tools for these pen jobs are teenagers and once they learn how then all of the local boom cars will then become much more effective.....

Sending the white paper off is fine. To treat mass quantities of cone drivers you need just the cones and a made to order, tappered, round lamp shade like tensioned silk screen, that drops in and fits snuggly against the cone with a tiny gap to the screen. Domes need to be silkscreen printed before forming ,if at all possible. If neither of these are applicable to your friends business, then again, teenagers are the answer.

Paul,
They might. If they are radial rings, straight out from center to outer edge then no effect. If they are a spiral then maybe a small effect that will cause you to coat the cone in the Microscale product with 3 or 4 coats. For circumferential rings, the ones claimed to "break up standing waves", I guess by making their locations permanent, the same coating spree will be needed.

I tend to coat most hard surface paper cones with two coats, three at the maximum due to increasing mass, slight though that is. Heavy felted paper cones need 3 to 5 coats. Aluminum cones just need a band over the rows of blocks and horrible plastic cones , depending upon how much damping material has been "injected" onto the surface might need 3 to 5 coats before the pattern is applied and 3 to 4 more after. You will have to sand these with 800 to 1000 grit garnet wet sand paper first to create enough tooth for the materials to adhere to. The idea of this stuff is to create a controlled boundary layer of fairly uniform character and get the longitudinal pressure wave a little above the speed of sound through air. Doing this just encourages phase coherent waves to be formed in the air and allows maximum energy transfer at the leading edge of the pressure wave as it slams across the surface in the boundary layer.
