MartinLogan Motion F20 overview
The MartinLogan Motion F20 is a passive loudspeaker from MartinLogan. Motion® F20 offers excellent detail, clarity, and power in a non-imposing floorstanding package. With the incredible trifecta of the Gen2 FMT with a Woven Fiberglass midrange and dual 6.5" aluminum bass drivers, it is well equipped to take its place in any home theater or 2-channel setup. Offering more bass extension and dynamics than its smaller sibling, the Motion® F20 is the ideal sweet spot for those balancing both performance and size. Mirror Edge Networks can confirm system matching, placement and installation requirements before supply.
