The driver has a built-in gasket. I wouldn't add to that. When the driver is attached to the horn, the gasket is squished flat making the seam between driver and horn throat very small, too small acoustically to matter. If you add another gasket, that may introduce a gap. This would cause a discontinuity right at the highest pressure point. You don't want that.
