I'm about to get dogs and children in the house. I'd like to keep my woofers undented and figure I need to build some speaker grilles for my DIY speakers. I guess there is at least two ways to do this: one is to get some kind of grille that is attached to the driverframe, the other is to build something own that in some way is fastened to the box or driver. Any ideas how this best is done is much appreciated! The speakers to protect are 2x18" boxes with flat baffles where the drivers are about 3" apart.
