![]() ![]() ![]() High efficiency (to reduce power compression for a given playback level).Low distortion at the expected maximum playback level.Tonal balance (how flat the frequency response is).Smoothness of power response (response at all angles).I attach importance to these factors in designing any speakers, but specifically horns: The details of how a hobbyist would design and assemble these systems are just a bit different. However both setups are really the same thing - a diaphragm of some sort driving a horn with a front and rear chamber. Since freely available software does not usually predict this effect, people see predictions of high frequency horn performance as unrealistic. The second is that the directivity characteristics usually play a much larger role in determining the on-axis frequency response for a high frequency horn than they do for a low frequency one. One is that cone driven horns are usually designed starting with the Thiel / Small parameters of the driver while the T/S parameters are usually not available for a high frequency compression driver. Sometimes it seems there is a disconnect in people's minds between a cone driver loaded by a horn and a compression driver loaded by a horn. It assumes basic knowledge of speaker design and terms. It is an evolving document, changing every time I feel like working on it. This webpage is my possibly incoherent attempt to explain how I design horns - all kinds of horns.
