>>I am just curious why did they already abandon the Ribbon Tweet from the essence after one new speaker with it and go back?<<
They didn't abandon the ribbon. You can still order Essence, and when that speaker is revised it will have a ribbon tweet again, but perhaps a different one. No credible ribbon supertweeter could be accommodated in the economics of the Soul speaker. Below Essence, I'm sure you'll continue to see dome-behind-lens, Druid-style.
