Post Subject: What mistakes can we avoid?Posted by rowuk on: 3/29/2020
TH,
Avoiding mistakes is something that we would like to do. It saves time and money BUT unfortunately the science of building loudspeakers is based on specs, not „Tone“ or „Sound“. Being an engineer can help make beautiful drawings but we all learn that industrial design and engineering often forgets basic rules of sound as they are not taught anywhere.
Romy has posted it many times: we do not hear the errors in frequency response, we hear the characteristics of the drivers /crossovers/room position that caused them. We discover how badly behaved „top rated“ drivers really are and that calculations/simulations report pressure of the soundwave, but not the Sound or Tone.
The speakers that you have posted pictures for have serious design errors in regard to phase alignment and that causes things to happen with the sound that cannot be „fixed“ by engineering effort. The list of things wrong with those specific designs is very long. I suspect that they simply feed the „anti horn“ community as they make the horns do things that only the deaf or sonically blind like.
If you are looking for a design, Romys Macondo is certainly well documented. A commercial offering that applies many of the Macondo Axioms is the Kornhent (formally called La Grande Castine ) https://www.kornhent.bzh/?lang=en. The entire speaker is very low priced for what it is. I am not sure that anyone could DIY build it for less money than it sells for. There are certainly many things that could be „improved“, but that starts with our ears, not hardware.Rerurn to Romy the Cat's Site
