Please note that the price indicated is for each speaker.

Foundation C1 offers incredibly clear dialogue to round out the front stage of any Motion Foundation surround sound system all in a space conscious design.

For those building out a surround sound system, the center channel is one of the most important pieces. The majority of dialogue in a movie comes from this speaker, so it is critically important that dialogue be clear. As with all Motion Foundation models the Gen2 Obsidian Folded Motion Tweeter S and Folded Motion Waveguide are used to great effect here to blanket your listening area in crystal clear dialogue. Foundation C1’s aluminum midbass drivers are also further enhanced by MartinLogan’s signature 2.5 way “Anti-Lobing” center channel design to provide the performance of larger 3 way designs in a much more furniture friendly package.
