About the CLS II
The CLS II offers a unique listening experience with its electrostatic design, providing a wide and immersive soundstage. It is particularly praised for its clarity in reproducing jazz and vocals, though it may struggle with complex orchestral pieces. The speaker requires a good subwoofer for full-range sound due to its limited bass extension.
