@wayne79259 since iFixit does not have a guide, take a look at [https://www.youtube.com/watch?v=RqXWYUZXtK0|this video] It's a true teardown with all it's trials and tribulations but ultimately you can see how to get to the grill. Or you could leave all of it intact and just follow [https://www.reddit.com/r/sonos/comments/mvrie6/long_overdue_sonos_move_teardown_start/|this teardown :-)]
While you work on your speaker, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
