Azurahorns are of glassfibre composite construction with cast resin flanges. The white colour is gelcoat, the first layer applied to the mould. I finish the horns on a spinner to give a soft alabaster appearance. The back is finished in thick white flocoat. The mounting holes are drilled for your driver using a template. The horns are packed in a custom made thick double ply carton.
