foam suitable for a jecklin disk?

[guosh]

hi guys, not sure i'm in the right forum but i'm gonna give it a shot anyway

i've been working on a DIY jecklin disk over the last month, using a 30.5" wooden disk and various kinds of foam (my most recent being a k-flex noise isolator)

problem is, its not been very successful. results haven't gone my way probably due to the absorption characteristics of the foam i'm using. i was just wondering if anyone had any suggestions as to what foam i could use to reduce hf reflections in a manner similar to jecklin's original idea off using lamb fleece?

cheers!

Use open cell foam or fiberglas/mineral wool. Jecklin disks are fantastic in appropriate rooms.

Enjoy!

hi andre,

thanks for the reply! do you reckon fiberglass fabric would work? i can't imagine sticking a piece of fiberglass that looks like it came from a canoe on my disk

regarding open cell foam, what kinds do you think would work? i'm still figuring out where to get these materials, and whether it'd be the correct ones.

thankfully i was able to make more wooden disks so i can afford to do some experimentation!

Not fabric, but insulation.

For open cell foam, you could order Auralex or Markertek acoustic foam tiles and cut those into the desired shape. Warning: Foam by Mail is NOT suitable.
