I'm sorry, but your english is much better than my Czech - I could not get enough info from that site to understand what their products are.

What you need for the inside of bass traps is a rockwool product that has a density of 40 to 50 kG per cubic metre - the thicker, the better as long as it does NOT touch the front panel.

The realtraps are a commercial sale item, not for home building - maybe you were planning on building some of these?

There is a link on that page that takes you to actual plans.

I hope that helped... Steve
