    Inspired by our ultra-high-end electrostatic loudspeakers, Motion FX features dual Folded Motion tweeters in a wide dispersion configuration, powerful bass, and folded reflex port technology in a compact, affordable package. Key to Motion FX’s performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (8-times that of a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.
