I find what he has to say really interesting. And not only does he "edit" speakers (fixing/improving someone else's design), he also designs speakers.
Every once in awhile I wonder if there's too much of a good thing when you tweak stuff (after over a decade of me modifying my cars). I'm totally a layman with speakers, but (for example) on the Klipsch 600 improvements...just listening through some headphones, I preferred the sound of the originals...which made me wonder if it's possible to have over damped the speaker with the extra sound insulation. Can too much insulation have "killed" the sound people enjoy hearing from Klipsch (for the record, I have never owned any of their speakers). I could totally be wrong since I wasn't able to hear either speaker live, but it was a thought. You can 100% overdamp a cars suspension...
