I was wondering what the correct part number was for the speaker grill that can close over the center speaker in the Meridian Surround 825W system. I am currently adding a center speaker but read in another thread that the included grill on the center speaker hole was too thin to reattach once a speaker was added underneath. I see in the various parts catalogs a number for a speaker grill but nothing indicates if it's for the grill that can reattach once a speaker is inside.

Thanks!
