Pick something to measure about a speaker and then do it.As I mentioned earlier in the thread I have no strong convictions either way about the subject that is primarily under discussion here. But as an electrical engineer I feel compelled to respond to this comment.
MEASURE the response to the step function and improve it.
The voicing is a deviation from this.
Just think of it - the process of engineering!
A violin is way different.
It always surprises me how non-engineers often and perhaps usually seem to view the process of engineering as being based primarily on measurements. While I can’t address speaker design specifically (my background is in the design of electronic circuits), in general the process of designing and developing an engineered product involves A LOT more than measurements. First there is the design process, done on paper and/or with computer-based software tools. That is often the most major part of the entire effort. Then extensive ANALYSIS is performed, on paper and/or with computer-based software tools. Computer-based simulations may also be performed. That is followed by fabrication and test of a prototype. Testing of the prototype, in the case of an audio component, will include both measurements AND LISTENING. Inevitably changes will be made to the design during those phases of the project, followed by further measurements and listening, and often additional iterations of the design, analysis, and simulation phases of the project.
In other words when it comes to development of an audio product, at least one that is properly done and is intended for audiophile (as opposed to mass market) applications, "voicing" is one of several integral and important parts of the overall engineering process. Not a deviation from the engineering process.
