Ahhh timing
I do get what you are saying Folsom but I do find that what materials are in the speaker and how the speaker is constructed all contribute along with driver material and speaker dispersion pattern and definitely the wire, connector materials and crossover parts all add to the near infinitely variable cocktail of the end sonic character of a speaker... and definitely some speaker manufacturers take a tonewood approach to resonance within a speaker design with the choice of timber in a box speaker. In the end it’s all about the mix.
I did a lot of trial over years of different materials for damping components with the Maggies as the review tool. Marble and granite sound different... calcite or glass, metal, hardwood, bamboo, carbon fibre... it all added to the subtle characteristic flavour within the sound. My least favourites were invariably granite and acrylic. I am allergic to both musically. The first rings like tinnitus and the other is musically numb and unfeeling like floating on a sea of anti-depressants (I imagine).
