Wharfedale EVO 4.S Surround Speakers

Evo4.s

Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN.

The primary focus is on the AMT development resulting in a radically different way of reproducing high frequency detail efficiently and accurately. Similar cabinet technology to ELYSIAN provides a stable and solid foundation for the drive units with radiused edges to help integrate the driver output with the room acoustics. In addition the unique SLPP bass reflex system, as developed for ELYSIAN, is now incorporated in EVO4.

沃夫代爾（Wharfedale）的新型EVO4源於廣泛的研發工作，該研究產生了ELYSIAN旗艦揚聲器，並藉鑑了ELYSIAN涉及的許多技術。

主要關注點是AMT的發展，這導致了一種根本不同的有效且準確地再現高頻細節的方式。與ELYSIAN類似的機櫃技術為帶圓角邊緣的驅動器單元提供了穩定而堅實的基礎，有助於將驅動器輸出與室內聲學集成在一起。此外，為ELYSIAN開發的獨特的SLPP低音反射系統現已納入EVO4。
