Martin Logan Motion 30

Powerful compact center channel speaker with a Folded Motion™ tweeter, high-gloss piano-black finish subtle angled top. Voice-matched to MartinLogan ESL speakers. 

Inspired by the clarity and detail of our ultra-high-end electrostatic loudspeakers, Motion 30 features an exquisite Folded Motion tweeter and powerful bass technology in a compact and affordable package. Key to Motion 30’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.
