Not not noticing a difference.
Tested a song that had some serious sibilance & it still has it.
Though my cut of the shelf liner was crooked as f*ck, not covering all of the metal parts & some of the liner even covering up parts of the actual driver.
No pdf templates for the correct shelf liner cuts? All I seen are the ones for the memory foam sheets.
Speaking of which, tomorrow I'll go get some memory foam & felt sheets at a art supply store & see how they work.
