Be aware- wood horns in the bass/bid region are difficult to keep from buzzing (as if you didn't know that...) EAW uses thinner bendy (1/4"?) plywood to make the flares, and fills the back side void (behind the flare to the case) with expanding foam. (just like the 10 pi) My fiberglass horns are rigid enough that no foam is needed- but I have a big case around them for portability.Boy, nothing like a fully loaded 3 way system, with about 2K watts per side.... (outdoors- 30 ft back...)
