Enjoy powerful sound with the relatively small footprint of the piano black MartinLogan Motion 20 Floorstanding Speaker. It measures only 6.8" wide and 11.7" deep to occupy a comparatively small area while accepting up to 200W of power from your amplifier. This speaker is equipped with a 1 x 1.4" Folded Motion tweeter and two 5.5" aluminum cone woofers with a rear-firing bass port for enhanced low frequency effects. This speaker can be bi-amplified thanks to its bi-wire binding posts.
