Here are my impressions so far between the Dreve Fotoplast S-IO and Egger LP/H

Overall both resins are good. I might recommend the Egger more for DIYers because of it's shorter curing times and thickness. But you can't go wrong going with both.

What about cure wavelength?

Both require 320-400nm

Dreve polylux 1000N curing machine outputs 315-400nm
Egger EL1 curing machine outputs 360-390nm

Another thing not related to resins but to lacquer is that Egger L/PH lacquer requires 4-5min to cure. Dreve Fotoplast lacquer 3 takes 60sec

A short reflection: Knowledge of musical instruments, e.g. the ability to visualize a drum kit and embed it in space is very helpful in creating a crossover and arranging the scene.I love the live sound of drums. With all of high tones and sabiliants from cymbals. And of course blast beats :imp:. :yum:

sanekn nice work :thumbsup:
Thank you sir! Now I have 4 pairs left to make.

It's for my friends, hardcore band Weaksaw.

Now I have 2 members having a strange ear canal form. The tip is wider than the canal so it's making it imossible for them to fit the shell at all. I guess, I need to sand down the tip a little. Will see.

This is my taste in music. :L3000:


I have a complex question. I have noticed in some projects (more than 6 drivers) additional driver with elongated tube (20-30mm). Is this driver included in the kit to improve the scene? It is full-range tuned? (In my opinion they are behind the high pass filter). How to reconcile phases in this configuration? For example, I recognized SWFK.

It is a high frequency driver. SWFK is a tweeter/supertweeter, you will always highpass it. The long tubing is an attempt to correct phase shift caused by a high pass filter.

Thank You!

what did you use to make the white plates?

Fotoplast + white dye for epoxy resin (with small drop of yellow). Logo is a piece of paper:] I am waiting for the ordered engraving laser.

I advise everyone to be careful about the contamination of uv lacquer. I was very careful and cleaned exactly the shells, but some micro dust got probably through the brush to the container. Sad: / I hope they fall to the bottom of the bottle.
