The Sierra Tower and Horizon looks beautiful. What would make it perfect if there was no grille holes. I'm wondering if it's possible to eliminate the grille holes.

Dave has mentioned somewhere that it's not possible to put magnets inside because there is no veneer to cover them. Another person suggested drilling from the inside to place the magnet but it would be difficult because of the bamboo.

Does anyone have any ideas for Dave how to get magnetic grilles or any other grille option that wouldn't require visible holes in the front of the speakers?
