Speaker Grill Removal

[sum escape]

I contacted Tiara for guidance and struck out. I need to remove a speaker grill (and speaker) to access some wiring that got disconnected by a technician long gone. A photo of the grill is attached. I have tried prying it off using a thin blade putty knife, "tested" corners for potential clips or push in "fastmounts", etc. It actually looks like it is just "pressed" in a held by friction. The grill is flush with the wall it is mounted in. Any other ideas you all may have are most welcomed.

Would it be possible to remove the larger wall panel?
Then you might understand how the speaker grille is installed.
Press fit
Glued in
Or some other means

I wish there was another way into the area, but it is in a corner and panels are solidly put together with glue. Thanks

Who makes the speaker?

Sledge hammer??? Usually they are friction fit. I would try prying harder. I just took a couple of speaker grills off and they were just friction fit.
