RE: Front horns: FR cone vs. comp driver

Posted by Retsel on June 15, 2020 at 23:48:03:
The selection of diffuser and probably horn type plays a role in that cupped hands effect you are hearing from the Oris Horns. My Lowthers were mounted in conical horns and employed large mushroom shaped diffusers, like those used with the Beauhorn Virtuoso speakers. This improves the power response in the higher frequencies, and I suspect that it is the beaming in the higher frequencies which leads to that cupped hands effect.

The directivity of the high frequencies is determined by the throat of the horn, while the directivity of midrange is determined further down the horn towards the horn mouth. This is why a conical horn can provide better power response than the narrow throat Oris horns.
