Best Possible Speaker Grill

[DJFUTILE]

I'm in the prrocess of buildin some hooge loudspeakers for outdoor gigs, specs: Dual Sellenium 200 watt RMS 8 Ohm 15 inch drivers, 300 watt Dome Tweeter in horn, Box size - L - 550mm - W - 500mm - H - 1550mm, I cant decide what sort of metal pattern to use for a grill to cover the dual 15 inchers any ideas?

With woofers it really matters little, as the long wavelengths involved will make their way through just about any grille. Don't grille the tweeter.
