Stuffing Material for Sonotube (1 Viewer)

Just wondering what's the best acoustic damping material to use for a sonotube.

Thanks in advance for your advice.

Ported or sealed?

Sorry, it's a ported tube.

The easiest thing to do is line it with the foam from PE.

Goal is to have it look like this

Or you can buy blanket batting at the local fabric store and use 3M spray glue to mount it. The batting I used was about 3/4" thick. I trimmed it to the length of the tube and then glued/rolled the tube until I had several layers built up. Dan W recommended about 8#'s total. HTH...Mike
