MartinLogan

A New Standard in Affordable Performance.

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.

Legendary MartinLogan Sound

MartinLogan speakers are known for their exceptional articulation, detail and realism, regardless of the listening environment. By using advanced thin-film technologies and Controlled Dispersion, MartinLogan delivers a unique and unparalleled listening experience that is not commonly found in other speakers.

Gen2 Obsidian Folded Motion Tweeter S

The Gen2 FMT S offers effortless performance, unmatched by conventional technologies. By folding thin film material, MartinLogan is able to pack more surface area into a small space. Large surface area, light weight and low excursion means an incredibly fast and responsive tweeter capable of reproducing the most nuanced content with stunning detail and clarity.

Folded Motion® Waveguide

Enhances the Controlled Dispersion of the tweeter, blanketing the listening area with incredible detail and precision. Avoids performance robbing room reflections and provides a more consistent sound across a wider seating area.

Aluminum Mid-Bass Driver

Using trickle down technology from MartinLogan’s own Motion XT and Motion Series, the B2 uses the exceptional properties of Aluminum to maximize clarity, detail, and output from the mid-bass driver.
