I was looking for a way to use my old sub with my new shallow mount subwoofer box. My old sub didn't fit and I was contemplating whether or not I should buy a new shallow sub. But instead, I found this and it worked perfectly. It gave just enough clearance to use my old sub in the shallow box. So I saved a bunch of money by not buying a new sub!

the height is only 3/4" so if you need a full inch, you're going to be in trouble, like I am now. it's also only covered on 2.8 sides, there is an obvious top side which is rounded off on the outside edge, and a bottom side which is not covered at all. the sides don't quite make it to the bottom either. they're also made in china, if that makes a difference to you.
No, I would not recommend this to a friend
