Hello Troels.
I am very satisfied with the performance of these speakers, they really are overachievers. I had to limit the output of my 80WPC Bluesound Powernode because of how loud it gets. They feature built in magnets for speaker grilles. The front was painted with high gloss Jotun Lady Supreme Finish High Gloss paint and sides were veneered with D-C-Fix walnut veneer.

When building these speakers, I prepared them with built in magnets for eventual front covers. Well - the day is here and they now feature an even higher WAF. I tried to respect the cabinets form when designing these. I do not hear much of a difference, if not any, with the covers on. I will try to do a fair measure in the future. These speakers have impressed many listeners. I'm happy to share the drawings of the covers of there is any interest.
