I have a pair of DynAudio BM5A Mk II near field reference monitors and I needed grills to cover the woofers. I bought these hoping they would fit and they did! The grill is bent up from the edge and clears the speaker travel beautifully. They are rugged and lightweight, but cool thing is that they get held to the front of the speaker box without any glue, screws, or Velcro. Because they are metal and the woofers have such large magnets, they are held firmly in place and I can remove them simply by lifting them away from the speakers with my fingers. This way, i can protect them from accidental bumpage, but still open them up for recording. This is very cool and convenient. I recommend these grills very highly!
