@Hal Rockwell You have already done so well and trying out my mods, wanna test more? I bought chamois leather and I'm trying to improve the sound of with it. You don't need same stuff but something similar is doing the job. I think it improved the bass and made upper frequencies more even. I added chamois leather to the back. This is very experiemental and it need to be inside but easier to do for now outside and faster.
Is this thing has partial resistance to airflow or completely sealed?
