Thank you very much for your advice and when I correctly understand the volume should be 130 to 150 liters and BR 26hz?

You don't have to make guesses. This is now well understood. Use the manufactures numbers as they will be close enough. Enter it into the simulation. It will provide several volumes and tuning frequencies, then calculate the port. Very easy. Much easier that waiting for someone else to do your work for you and expect it to be correct.
