Can someone provide some insight into the correct amount of damping material that should be in the woofer area of the Kappa 9's? How tightly/loosely should it be packed? When I bought my K9's the first thing I did was open up the speaker to inspect the wiring. The acoustical damping material behind the woofers looked like big cotton fluff that had yellowed, molded and was stuffed very loosely. By loosely I mean it looked as if someone very sparingly stuffed the speaker with just enough so the stuffing would not fall down. Not knowing better I replaced it all with new speaker damping material. I think I may have over packed it too tight now that I have learned how it is important to replace the same amount as the speaker designer intended. Paul of PS Audio, who worked a lot with Arnie, has a video on YouTube where he says Infinity took great care in experimenting with the proper amount of damping material until they got just the right amount and then used the exact same amount in each speaker of the same line.
