That's the limp mass plan I've been looking at. Thanks, I'll have to do the math and find my nodes. Room sweep analysis is just showing slow bass decay, not any consistent peaks.

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)!

Recording studios is where ASC and their Tube Traps first found acceptance. Art Noxon is a highly degreed acoustical engineer, a true expert in a field with rather low standards, if not outright charlatans. Room Tunes, anyone? ;-) Studios build bass traps into the structure of the room/building, the reason being that to be effective at very low frequencies, traps need to be huuuuge. To call the flat panels containing 2-4" 703 fiberglass offered by GIK and RealTraps bass traps is a stretch. Products like the DSPeaker Anti-Mode are an effective non-acoustical means of dealing with room modes. |
