It's in the EU, and in particular Germany where customer protection is much stricter than in Denmark so you should have no problems. Contact the Forbrugerstyrelsen/klagerådet if in doubt.

I suspect it's chassis resonances. Have you tried dampening the piezos with either bitumen or silicone.

If I want to use silicone, do I just cover the whole backside of the tweeter or just the sides? Does it have to be a specific type of silicone?

Also, piezos are exclusively run by voltage and most of the piezos from Monacor (at least what I've seen) have a maximum of ~30 V.

No I have not, I have silicone laying around somewhere, so that would be easy to try, but how would you go about doing that?
Not clear if you mean on the outside of the Piezo or inside.

But the thing that confuses me, and makes me think they are somewhat broken, is that this problem didn't appear so clearly before Roskilde, as they do now.

Fill on the grooves on the backside of the horn first then make thick circular rings of silicone roughly 1cm apart also on the back part of the horn. Check that the driver bit hasn't come loose. If it has glue it into place. Cover the back of the driver bit with an even coat of silicone.

Must be non-acidic silicone, other than that no requirements.

Also try with a larger resistor value like 80-100 ohms instead. Don't worry, it will not lower the output.

But the siliconing of piezos, I always recommend doing that. They always improve a lot in sound when that is done. And I also will also note that I always take apart the driver section and glue it back into place. More often than not the serious vibrations it is subjected to inside the cabinet will shake apart a low cost piezo only assembled with 2 small screws.

"The sky above the port was the color of television, tuned to a dead channel"

Anyway I got a mail from PLUS-Elektronik.de saying that* they apollogize again for the very long delivery time.....which leads me to believe that I got a standard crap mail since i havent had any other emails from them* * then they go and and blame the distributor and they are sorry i dident get the first packaged bla bla bla and finaly that they are waiting for 100 pcs of the HP-10W
Right now im in Thailand enjoin the sun and sea so it is hard to ruin my good mood but PLUS-Elektronik.de comes very close.

If you're in Thailand maybe you can visit the P.audio factory?

I hope that you get your speakers soon. I think that I'll wait a little to see how this progress, before I order my set of HP10W.
It is after all the cheapest site that I could find.
