6" 2-Piece Steel Mesh Speaker Grill Black

Since there aren't dimensions (bolt circle, maximum speaker outer diameter, etc.) could someone who bought them please provide it here in the comments? I bought the 6 1/2" version and it was too big for my woofers, but I'm afraid to buy these without dimensions.

I used these on 5 1/4" speakers on my Yamaha Roadstar. They look better than the orignal grills. They are very sturdy and should last a long time.

Mfg. inserts the small ring inside the larger ring, and no easy way to dislodge..other than that, a quality product..use it as a an air-vent cover plate...
