Dear Arthur : Speaker supply stores carry Acousta stuff . A retailer
like Madisound which you can find at http://www.madisound.com has it .
Polyester pillow stuffing can be purchased at most fabric stores .

This is coverend in Section 1 (Materials Overview) of the LDSG - see
URL below. Hollofil Dacron stuffing is commonly used for pillows and
should be available at any fabric store. Acousta-Stuff is available
from:

Parts Express carries Acoustastuff and your local fabric
store carries regular polyester or Dacron. I have taken apart
pillows for some of the more premium brands of Dacron.
In any case, I might suggest first lining the walls
with 1/2 inch foam before you stuff.

Try using fiberglass. Cheaper and far more effective than ANY
other damping material out there. If you want evidence, see P.
24 Table 1.21 of Vance Dickason's "Loudspeaker design cookbook".

I might take a look, but it is hardly ever used in transmission lines,
allthough I did measure its effects. Foam is also very comparable
to fiberglass. There are many grades, thicknesses, and types,
of both materials.

There are two major "stuffing" reasons. One is to reduce
resonance and standing waves, and the other is the compliance
enhancement effect that another recent thread talked about.

Material that would be good for one effect may *not* be the
best material for the other.

Maybe Dr. Pierce could elaborate.

We are talking about lines here. Supposidly the main reason is to
slow the sound down, but you can't really get one reason without
the others.
