The Foundation C1 delivers incredibly clear dialogue to anchor the front stage of any Motion Foundation surround sound system — all in a space-conscious, furniture-friendly design. As the centre channel handles the majority of movie dialogue, MartinLogan engineered the C1 with their Gen2 Obsidian Folded Motion Tweeter S and Folded Motion Waveguide to blanket your listening area in crystal-clear sound. The signature 2.5-way "Anti-Lobing" design provides the performance of larger 3-way speakers in a compact cabinet.
