These are floor-standing, 3-way loudspeakers that also include a 6.5” passive radiator, increasing efficiency and limiting distortion. Our HF Waveguide technology produces superior imaging, allowing you to discern where on the “stage” the musicians were located during recording. The stylish S-H453F-K’s can handle the wide frequency range of DVD-Audio and SACD, two high-resolution audio formats that offer much higher quality vs. CD. And their magnets are shielded so they won’t damage your TV if positioned next to it. Engineered in the U.S.
