Folded Motion XT Tweeter
MartinLogan’s larger, low distortion Folded Motion XT tweeter boasts a radiating surface 40% larger than those found in the award-winning Motion® Series products. This substantial leap in size increases the bandwidth and efficiency of the high-performance tweeter for effortless center channel performance.
Slender Profile
When mounted on a flat wall, the EM-FX2 protrudes only 6.8″, making it the perfect surround channel speaker for large rooms, without adding unnecessary bulk or visual distraction.
