After reading a lot of material about EnABL, I organized the process for Fostex 127E like this:

1. 100 hours stock drivers break-in

2. Damar trifoil pattern
a - Not thinned, straight out the bottle. Only one generous stroke.
b - Is there a template for the pattern? How to calculate the painting positions?

2. 2 coats of thinned ModgePodge Puzzlecoat
a - At least 6 hours between the coats.
b - Thinned with water with care to reach a consistency that allows a confortable flow witht the brush.
c - Only to the cone? What about the dustcap?

Listen the drivers at least 10 hours and evaluate.

3. EnABL dots pattern using Poly Scale
a - Must be tinted? Am I able to view the dots and then have control over the painting process if using raw white?
b - Thinned? What proportion? With water?
c - One stroke of the spots is enough?


4. 3 coats of thinned Microgloss only in the cone
a - 50% Gloss thinned with water
b - Listen the drivers before each coat and stop before the 3rd coat if you feel the driver came alive.

5. 1 coat of thinned Microgloss only in the dustcap
a - 50% Gloss thinned with water

6. PVA spot on the center of the dustcap

7. Coat only PVA spot with gloss 50%.

8. Add stealth spots in the mid ring.
a - What is the mid ring and stealth spots?

I know the process varies a lot. It is a like a guide I made for myself, there are some doubts in red and also can be useful for other fellows.

thanks

There is an EnABL how-to thread.

I will just address the trifoil template question. In emulation of what P10 does I made two templates from cast off 50 cent drivers one cut to the lower triad and one cut to the upper triad. There are some images of this from P10's workshop shots. The cone material is substantial and holds up well while handling.

But I did not apply it yet.

Here is the thread Lon refers to EnABL How-To for Fostex FE127e and other speakers

8/ stealth is the use of clear pollyscale. The mid ring does not need to be stealth. Exact placement done using the tap test. Ends up coninciding pretty much with the ring of the trifoil closest to the dustcap.

3/ any but the flat pollyscale will work. A contrasting colour is useful, particularily while practising, to give you feedback on the application.

One stroke... you need to practise and get a handle on your tools & skills. note that weather, the state of your tools, the state of the paint can all make the way the pollyscale goes on different. No substitute for practice.

The Pollyscale does not have to be thinned, but make sure it is well mixed. If you do as many drivers as i do, and the paint pot remains open for long times, you will find a need to restore the viscosity of the paint.

2/ the dustcap gets treated the same as the cone. Particularily during the 1st coat, while the cap is wet, it is very fragile and easy to dent if you are not careful

Thank you guys,
I have already read this referenced thread "EnABL how-to" many times. What I stated here is what I understood and I what I could gather from almost 300 messages of that topic.

Now, my guide is the following:

1. 100 hours stock drivers break-in

2. Damar trifoil pattern
a - Not thinned, straight out the bottle. Only one generous stroke.
b - Is there a template for the pattern? How to calculate the painting positions?

2. 2 coats of thinned ModgePodge Puzzlecoat
a - At least 6 hours between the coats.
b - Thinned with water with care to reach a consistency that allows a confortable flow witht the brush.
c - apply over the cone and dustcap with care.

Listen the drivers at least 10 hours and evaluate.

3. EnABL dots pattern using Poly Scale
a - Tinted can help.
b - Not thinned.
c - One stroke is enough.

4. 3 coats of thinned Microgloss only in the cone
a - 50% Gloss thinned with water
b - Listen the drivers before each coat and stop before the 3rd coat if you feel the driver came alive.

5. 1 coat of thinned Microgloss only in the dustcap
a - 50% Gloss thinned with water

6. PVA spot on the center of the dustcap

7. Coat only PVA spot with gloss 50%.

8. Add stealth spots in the mid ring.

I'm still no able to find a template pattern for the trifoil. I read somewhere about 9mm and 17mm from the outter edge of the cone, but I'm not sure yet about it. Any help?

thanks!
Highef

No template at this point. To make the template i use you need the cone from a dead FE126/127

Some info her planet_10 hifi
But mostly here Fullrangedriver Forum / Modded FE126e FE127e

Dave,
thank you for the links. I think I got everything now. See how I updated the step 2 below.
Another question (). I read that the puzzlecoat would be like thinned PVA (wood glue). Is that correct?

thank you for the support.
Highef

1. 100 hours stock drivers break-in

2. Damar trifoil pattern
a - Not thinned, straight out the bottle. Only one generous stroke.
c - Divide the cone in 6 parts of 60 degrees. Mark the start and end points of each arch. 3 segments 9mm from the boundary alternated with 17mm.
b - Use a Q-tip to draw the arcs with Dammar and link all the arcs.

2. 2 coats of thinned ModgePodge Puzzlecoat
a - At least 6 hours between the coats.
b - Thinned with water with care to reach a consistency that allows a confortable flow witht the brush.
c - apply over the cone and dustcap with care.

Listen the drivers at least 10 hours and evaluate.

3. EnABL dots pattern using Poly Scale
a - Tinted can help.
b - Not thinned.
c - One stroke is enough.

4. 3 coats of thinned Microgloss only in the cone
a - 50% Gloss thinned with water
b - Listen the drivers before each coat and stop before the 3rd coat if you feel the driver came alive.

5. 1 coat of thinned Microgloss only in the dustcap
a - 50% Gloss thinned with water

6. PVA spot on the center of the dustcap

7. Coat only PVA spot with gloss 50%.

8. Add stealth spots in the mid ring.

thanks!

Both Modpodge & white wood glue are PVA formulations (there are a zillion recipes for PVA). I have found over time that the gloss puzzlcoat-like products retain a higher level of flexibilty when dry and are better suited to the job. I like modpodge (the original Puzzlecoat brand is no longer available).

Considering that white PVA wood glues are forumlated, well, to glue wood together, you probably wouldn't want much post cured flexibility?
