The idea is to absorb the wave that travels along the baffle before it has a chance to defract and rereadiate.

The material pictured by Vince35 is a loose speaker damping material which may or may not be largely made out of wool.

The JMLabs above have a round ring which is probably the worst possible shape, the square cutout is better, i like something even more complex -- i use stars with a prime number of points and cut such that the leading edge of the cut is at an angle. I typically use fairly dense (& thick) woolfelt.

Default Isobarik subs

Hi BusterNo1, the idea is to space the drivers far enough so that mechanically, they wont touch each other at max X.
As far is the ring around the tweeter, I used an old foam mouse carpet that was laying around. Cheers

With this recent trend for actually DIYing drivers, I'm going to have a go at a berylium tweeter...All I'd need is a sharp penknife and some double sided sticky tape and some cardboard.

I wish! But in their promotional material, the construction doesn't look difficult after you actually manage to cut into the stuff. I wonder how it sounds compared to the non "be" version.

Berylium is a VERY poisonous material...

Aye, that as well...

Don't know what all the fuss is about really. They sent people into mines, or chemical factories or asbestos ghost ships...etc
I'm sure the ppl who make be tweeters are just as safe and wrapped up.
