Martin Logan Motion Foundation F1 (Please Call/In-Store Only)

Please note that the price indicated is for pair.

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.
