My understanding is that they are somewhat narrow, but will absorb some surrounding frequencies also.

I bought this stuff for the limp mass. It’s better than the vynil stuff: https://www.ebay.com/itm/Neoprene-Rubber-Sheet-Strip-1-4-Thick-x-24-wide-x-10-Feet-long-FREE-SHIP/281773665932?hash=item419b04ee8c:g:aOQAAOSwuLZY4J0t i think i used 1/8” for 63hz, and will use 1/4” for 50hz. It all depends on desired cabinet depth. Thinner neoprene requires deeper cabinet. |
I just spend an ABSURD amount of time researching this. I landed on ASC IsoThermal TubeTraps. They have built-in diffusion (or absorption)!
