"Just a point of clarification. Any horn is a "wave guide". Cupping your hands together and yelling through them would be considered a wave guide. A CD or Constant Directivity horn has better dispersion than a Tractrix for example. BUT....a CD will have a natural roll off above 6K or so, so you need to compensate for that roll off. If you look on any of the pro active crossovers you will see a "CD" button. That adds a bump above 6K or so" - DJN
