Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 4i feature exquisite Folded Motion tweeters and powerful bass technology in compact and affordable packages. Key to performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (much larger than a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jawdropping clarity—certain to inspire envy in audiophiles and non-audiophiles alike. Precision Vojtko™ crossover topology features custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low DF electrolytic capacitors for a seamless sonic presentation. Motion 4i bookshelf speakers can also mount upside down to facilitate placement high on a wall.
