They look good and they are very tough. I've had one of these on a 13.5" sub in an SUV for over 2 years. The sub was face up and it was always getting stuff tossed on top of it. It has never dented or failed. When it came time to buy more subs I knew they had to be JL Audio subs and grills. I'm building a home theater riser with some subs in it so I knew I'd get this grill for those. I don't want anyone to step through my subwoofers that are sitting on top of it. It shouldn't happen because the home theater seating will being over the top of the subs, but it's more of a just-in-case.
Pros: Rigid and clean looking.
