Thank you for helping!Good luck, GV sounds great and is easy to use. I'll have a go at answering these but I'm still a beginner so others will know better.
1. I just used cheap local paraffin wax, I can't imagine it makes a huge difference. You'll be sanding it down later anyway.
2. I had 2 open and 2 closed I think. You can measure/listen and adjust to taste before you close it up
3. I used 2mm ID tubes. I would imagine you'd lose some treble if you used 1mm ID tubing for the tweeter. Maybe that is desirable to some. With 2mm ID tubing all the way you'll have more options for damper placement
4. I don't think wires will make much difference, if you're going to be able to see them then take that into account
5. I had no problem using normal resin dyes. Of course exposure times will vary so you'll need to experiment.
6. Not tried flakes but added some black mica for one pair. Don't recall having any problems with exposing it and the specs do hide any imperfections/bubbles quite well as a bonus. I'd say you should be fine with flakes, unless you go over the top
So i will order 1 and 2mm ID tubes and try to use only the 2mm ones. hope to have enough space at the end of the shell
Also I am going to order a Dayton iMM-6 for measuring. Didn't plan that before.
