Description
Motion i Compact
Speakers
Inspired by the clarity and detail of MartinLogan’s
ultra-high-end electrostatic loudspeakers, Motion 2i, 4i, 6i, and 8i feature
exquisite Folded Motion tweeters and powerful bass technology in compact and
affordable packages.
Folded Motion Tweeter
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 jaw-dropping 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.
Engineered Curves
Flexible installation options allow table top or on-wall
installation of all four speakers. The Motion 2i and 4i bookshelf speakers can
also mount upside down to facilitate placement high on a wall. The Motion 6i
and 8i mount horizontally or vertically around a wall-mounted flat screen
television.
