Hi Troels! After the first 30 hours of listening the sound has improved. I allowed myself some cabinet tweaking. I used an extra 30 mm polyester damping material 0.15 sq.m per cabinet, placed in the top of front chamber. I suppose the extra damping will be not required after full break-in period. Resistor, which is used for the tweeter is 2.7 ohms.
It is hard to describe the sound correct but I think the sound is huge exceeding all my home audio dreams. I have never heard such bass - open, fast and solid. Unbelievable!
I want to thank you for your truly great work!
A few photos of the speakers are attached.
Best regards Valery
