Chosen Solution

So i recently got a UE boom 2 and i knocked it off my desk and when it hit the leg of my desk it left a huge dent in the fabric/metal grill. Is it possible to push it back out?

Yes you could push it back out but you would end up making a bit of a mess with the speakers looks. The covering is glued on and you will likely loose the water tightness. I would just live with it. Sometimes the cure is worse than the illness ;-{
