MO4BL - Martin Logan Motion 4 Glossy Black Compact Bookshelf Speaker (Sold As Each)

Audiophile Performance without an audiophile price

Inspired by the clarity and detail of our ultra-high-end electrostatic loudspeakers, Motion 4 features an exquisite Folded Motion™ tweeter and powerful bass technology in a compact and affordable package. Key to Motion 4’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—certain to inspire envy in audiophiles and non-audiophiles alike.
