What in your mind represents real technological advancement.

To be a real advancement the technology must improve the sound quality. Just extending the bass or the high end can't be call an advancement if it doesn't sound better. If the bass goes " lower " but is muddy or the highs go higher but are " bright and forward and irritating " then that does not improve the listening experience. So the question is what improvements make a speaker more enjoyable to listen to.

Soundsreal I was not harsh just 180 out of phase with one way broadcasters....

speaking of driver breakup, I could not agree more with Ralph, we are just now getting affordable ( if $50k of capital investment is affordable for small speaker manufacturers? ) laser scanning tools to show driver out of phase behavior, which is 100% trash

Breakthrough for me was giving up my multi component rack of separates and buying a Peachtree Nova 300. Built-in superb DAC, unprecedented specs (111db SNR) 300WPC @ 8ohms, stable from 4>16ohm, USB and optical inputs all in one small beautiful component. Best smooth yet punchy sound ever, my component buying days are over!

The advancement is here but is yet to be fully utilized. For some time now it’s been possible to accurately correct all dynamic speaker distortions, in both time and frequency domain, but thus far high end speaker manufacturers have resisted from releasing a magic correction box that would eliminate distortion - with pre-distortion. Reasons are obvious I suppose; Specifically, money. When people discovered that a dsp corrected (relatively) cheap speaker sounded indistinguishable from a corrected expensive speaker........
