Avi - Go with step 1. It works great! One of my kids' friends dented one of my drivers too. Make sure there's no dust inside the tube before sucking! You are in total control of the suck amount and you can hear the cone pop out (no vacuum noise) to know when to quit sucking. Less chance of damage than the vacuum method. But not nearly as dignified. BTW - the vacuum method didn't work for me but step 1 did. I guess I suck more than my vacuum. Or maybe my vacuum just sucks.

Don't die with a clean shop!
