Martin Logan Motion Foundation B2 (Pair)

The largest Motion Foundation bookshelf speaker serves up impressive detail and scale completely unexpected in its class.

The versatility and relatively compact size of bookshelf speakers have long made them a popular choice. Those looking for a fuller sound stand or shelf mounted solution would be hard pressed to find a better value than the Foundation B2. Its 6.5” aluminum midbass driver offers impressive bass while the Gen2 Obsidian Folded Motion Tweeter S works within the Folded Motion Waveguide to blanket your listening area with beautiful sound. Foundation B2 is also fully compatible with STAND25 to create a solid stand mount solution.
