Inquiry (采购产品): speaker grille I'm interested in buying perforated metal (aluminum probably best) for a speaker grill application. I suspect round, staggered holes are best for this, but I'm not sure what hole size or opening% is best. Can you help me with the following: Which material/configuration is most successful as a speaker grill? What colors are available? If you just provide bare metal, how can it best be colored and by whom? What costs can I expect. I picked your company from a long list because you're in Michigan where I grew up!
