The above responses are not uncommon. Loudspeaker voicing, spectral and timbral characteristics, the basic sound of a loudspeaker company’s designs is understandable and to be expected. Richard Vandersteen has a sound he goes after, as did David Wilson. Everyone claims to be trying to achieve the "accurate" reproduction of acoustic instruments and voices, yet every designer makes a line of speakers that makes recordings sound different from that of other designers.
Danny Richie has addressed the above arguments (the term not used in it’s pejorative sense) in some of his other videos, and does so again in this one. His argument is: Would a designer think to himself "I know what would make for a good sounding loudspeaker; I’ll operate two drivers in such a way that they are out-of-phase at the crossover point where the output of the two drivers meet, the result of which is a 12dB hole in the loudspeaker’s frequency response?" Danny says "No, no loudspeaker designer thinks that."
If you look at John Atkinson’s measurements of the Eggleston models that have been reviewed in Stereophile, you will find the same "hole" in the frequency response Danny did when he measured the model a customer sent him. Is a frequency response hole (12dB down from the speaker’s midean output) a loudspeaker voicing choice, or a design fault? In this video Danny Richie gives you his opinion. You are of course free to disagree with it, and even like the sound of an Eggleston speaker.
I myself have never heard one, but I find the topic of loudspeaker crossover design an interesting and important one. Is a 12dB hole in a loudspeaker’s frequency response a "Problem that doesn’t exist"? The "corrections" Danny came up with for the Klipsch models sent him by customers have been incorporated into the Mk.2 iterations of those models by Klipsch themselves. The crossover ideas Danny suggested and offers for Magnepans are now offered in Magnepan’s own "X Series" upgraded versions of some of their models. Are the X Series versions a solution to a problem their standard versions don't have? Is Magnepan cynically catering to a gullibility they know some audiophiles fall for? C'mon, you know Magnepan better than that!
