I’m one of ’the 20.7 will be my last speaker’ guys. Moved from 3.5 to the 20 many years ago, which was a huge step up. Going from the 20 to the 20.7 was more subtle, but still worth it. The few minor issues I had with the 20 (ribbon tweeter quite a bit faster than the rest) were solved with the introduction of push pull quasi ribbons for both mid and bass drivers. There’s less need to compensate between drivers, which enables the use of a much simpler crossover. They're now much more ’of one piece’.
Despite these changes they still have low sensitivity, so the need for a lot of power has remained. Think at least 300 watts at 8 ohms, preferably with the ability to double its output at 4 ohms. Smaller models may need less though.
