Dampening - I was originally going to use some fiberglass sound panels. It was too friable and I changed direction.

I found some egg-crate foam with similar NRC ratings (below 500Hz) as the Basotect. I followed Matthias' guidelines and only covered half of the rear with dampening material.

I then covered the whole back inside and added some AngelHair in the bottom behind the woofer. Stopped the slight boominess that I heard. I did use the AngelHair in the top instead of the wool because I already had it. (100g per speaker at this point.)

I think angel air is Dupont plastic fiber material with an empty channel inside. Used for sleeping bags or winter clothes. Pure wood is certainly better for what we need here.

Mbrennwa gave links before in this thread for Melamine foam, iirc. A very good material.
 
Pasta material is far better than meta material !

Sheep wool is superior to angel hair

Melamine foam (think to the magic sponges made with material) is all open foam so play the same role. You can add stuffing in the top with angel white sheep air, perhaps it plays a role towards the highest frequencies of the Faital... If I remember it wastunned after.
 
Evening all.. This is one of the first of what will likely be a lot of questions! Have a morning set up with a friend tomorrow who builds fine furniture, and has a full wood shop. Lifesaver on this project. I'm hoping tomorrow we can get the outside cabinet panels cut. Question about the internal braces however. I picked up some 3/4 MDF today for them, but the dimensions in the paper seem to be scarce. I"ve seen some pics on the thread where some guys made the full brace including the "L" section, and some who seem to have removed the L section. I'm assuming there needs to be a certain distance from where the brace is labeled Front, to the end of the recess where the remaining material starts to accomodate the drivers? I've seen a few examples (I believe) where one brace has the L and the other does not.. I'm likely over thinking this already! Pics for fun tomorrow!
