Motion Foundation F1
The Foundation F1 is perfect for those desiring the performance of a floorstanding speaker but would prefer a more compact design.
Offering a tighter footprint than the larger Foundation F2, the Foundation F1 is ideal for those with smaller spaces. The star of the show is the Gen2 Obsidian Folded Motion Tweeter S working in tandem with the Folded Motion Waveguide for shocking levels of clarity, detail, and immersion. Filling out the sound are custom 5.5” aluminum drivers that combine high strength and low mass for impressive speed and detail. Foundation F1 is a great choice for high performance in modestly sized rooms.

Motion Foundation C1
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

Motion Foundation B1
Small in size but not sound, the most compact Motion Foundation model offers unheard of performance from such a versatile size.
The Gen2 Obsidian Folded Motion Tweeter S, Folded Motion Waveguide, and 5.5” aluminum midbass driver work together here to create a completely unexpected and engaging experience from a compact footprint. Foundation B1 is ideal for small spaces, especially when combined with a subwoofer, to create a highly musical, detailed experience wherever high quality sound is desired. Foundation B1 is also threaded to work with our STAND25 to create a stable stand mount solution.
