Speaker Grille Magnets

[28BlusLater]

My MartinLogan Prefaces are amazing. However, the grill on my Front Left speaker is a little loose. The magnet on the top right of the speaker is getting bad and just touching that part of the grill, it lifts up, then snaps back down, but doesn't stay tight down like the other sides. I tried putting the other grill on it to see, but still had that problem. It's the magnet on the speaker. Is that too small of a thing to call MartinLogan over or is it alright to call?

I know this is a quick question, but I didn't know where else to post it.
