Joey,
That is a good question,the new Memento's have the ring radiator. Sourced from Scanspeak I believe. IMHO, the Dynaudio Esotar in the Guarneri Hommage ( which are my version) sounds smoother and is more extended than the radiator in the Memento.( Having heard both)
Also, the Hommage uses the Audio Technologie mid/bass driver( which I also feel is a superior mid/bass driver to the Memento's ( a 150mm doped paper unit I suspect sourced from Dynaudio) and has the ability to be bi-wired which the Memento does not. ( This is again IMHO a major drawback, since I am a very strong believer in bi-wiring).Lastly, the Memento's cabinet are made solely from Maple and again appear inferior to the Hommage's. The Memento's are also far more expensive. I still would have considered them if I thought they were actually superior, however, like many things in audio, the latest sometimes can be a marketing gimmick and actually I believe they are inferior.
