The cover works fine and I appreciate the design; however, there are two flaws. The first is that it is extremely tight, and the only way to successfully get it on, is to put the subwoofer on the floor with the grill facing down, and pull the cover onto it from the now-upward-facing back of the sub. The second issue is the zippers absolutely suck, and after a short amount of time, both pull tabs on the back access have fallen off and vanished. These are both well-documented issues in various RCF / pro-audio / DJ user forums online.
