Now I'm thinking something else happened.. maybe something very small fell into the hole in the magnet and are now trapped in there, starting to vibrate when playing music..

But then again, I'm almost certain that the ratteling sound doesn't come from the center of the HP10 but from the side where the connectors are.
I don't understand it.

You can try bending it gently with something non-conductive as see if it's that.

Also, the speaker won't like playing 20hz. Give it 50hz at least.

It has something to do with the rim of the HP10W. It doesn't begin until I hit a certain volume (which isn't loud at all) but then continues to be there even if I turn down the volume again, untill it disappears again when it's very low.

I took a small piece of dumb wood, that fitted trough the holes in the grill, and while playing very gently pressed the shiny part of the rim, where the rattle comes from. This made the rattle disappear, but only for a second or so.

Could it be that something is stuck on the backside of the rim, that starts ratteling along? I tried looking through the reflex port but the view is very limited.

It's awefully annoying, both to listen to, but also the fact that I don't understand what's causing it.

Edit: The rattle is also triggered by bass and kicks when listening to music.

My guess it's one of the screws you used when fastening the driver that has come loose.

(which is one of the reasons I remove them entirely when the silicone is hardened)

I can't decline that, but I think it would be unlikely, because I screewed them in pretty tight and also used plenty of sealant.

I will keep on investigating.

Dentist equipment would come in handy in this case

You could try and record the sound and post it, btw.

Yes indeed it would!

Good idea, I'll try that tomorrow.

So far the only thing that made the sound disappear (for a second) was to gently push the rim through the grill. I don't know how the rim is made, but if it's made of layers, it's as if the layers aren't pressed together correctly.

You basically just building a half Boominator. Many people have done that already.
