ok, i agree with that. i just did a test and pushed on the cone of my shiva, a JL audio 10W6, JBL T80, Energy 8" mid, and a wharfedale mid, ScanSpeak 5" mid, Audax 8"...no scrapes. got scraping sound on an 10 year old pyle 10" along with a 6" energy mid.
I need to get some sleep...i'm so bored i'm pushing on speaker cones! haha
