Great fit, very sturdy

Crutchfield Customer Review (What's this?)

At first I was worried that this grille is made of plastic, but right out of the box it was clear this is a very sturdy, rugged plastic. It fits great over the subwoofer and has a very clean, professional look once installed. Around the edges it doesn't quite come flush with the subwoofer enclosure, leaving about 1/16th of an inch of space. This may bother some but fits very securely onto the speaker itself and that's what matters, and the gap isn't visible at all.

Pros: Fits well, looks good, feels strong

Cons: Some might not like that it isn't a flush fit against the enclosure

Crutchfield Customer Review (What's this?)

Bought for Polk Audio MM1240D. Would have preferred a better fit.

Pros: Looks okay, not great.

Cons: Doesn't fit completely down over the Polk Audio woofer it's made for. Leaves about a 1/4 gap between grill and speaker enclosure.
