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.
 
 
 
 
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 Gen2 Folded Motion Tweeter S, 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.
 
 
McCracken-Vojtko Crossovers
The culmination of combining extensive anechoic, in-room measurements, and multiple blind listening tests with the low distortion philosophy of MartinLogan's signature Vojtko Crossover. Through this process each speaker was refined to achieve the best performance.
 
 
Controlled Dispersion
Room acoustics are vital, as everything in the listening room has an impact on speaker performance. MartinLogan minimizes these harmful effects by focusing the sound into the listening area, increasing flexibility, clarity, and placement options, regardless of the room's design.
 
 
Aluminum Mid-Bass Driver
Using trickle down technology from MartinLogan's own Motion XT and Motion Series, the Motion Foundation Series uses Aluminum cone woofers to maximize clarity, detail, and output.
 
 
Secure-Lock Grilles
Stealth mounting tabs securely hold the grilles in place allowing the listener to customize the appearance of each speaker. Creating a unique look; leaving the grilles on, off, or even rotating them to change the grain of the fabric providing maximum aesthetic control.
