Fiberglass/angel hair looks best. Lets see distortion measurements.

Very little difference between fiberglass and fiberglass/angel hair...
![]() The wool felt was only used on the vertical walls, I want to try that with fiberglass with all walls covered with wool felt. I ran out of time to be able to seriously test more combinations. The wiggle at 400 seemed lowest on the fiberglass/wool felt combo. Compared to the speaker on baffle without box: ![]() Last edited by wesayso; 2nd December 2014 at 05:29 PM. |

Another day of testing with various materials and placement of those materials.
![]() Fiberglass stuffing enclosed in wool felt gave the smoothest curve (again). Very small trace left of the wiggle just before 400 Hz. It is in the empty chamber plot but not on the baffle alone. Can't find a sweet spot to remove it entirely yet. |
