"It seems that later (after TT) products migrated to a very thin foam interface that essentially collapses under mechanical load while forming an air seal."
I did not notice any kind of seal when removing the speakers from the cabinet , (maybe because New Thiel had removed them first ?) although they did tend to stick a little the first time I removed them , I thought that they were sticking to the paint .
Should I be contacting Rob about the availability of these foam seals for the 2.7 speakers ?
Thanks Rob
