Rwwms other horns are availible AG not the only source and molds can be made for less if construction of horn uses diferant material than ABS. I perfer fiber glass and carbon fiber,wood, aluminum and as far as wood changing sound so, if the wood horns are constructed proper they wont have any changes that would - effect sound quality and I feel wood has far better resonace character than plastic anyway.And I bet it costs more for construction of a turned wood horn than a injection molded AG horn [I worked with plastics for years plus I employ wood workers to do hand turning so know what this costs].But with all things audio YMMV
