Small in size but not in sound, the Martin Logan Motion Foundation B1 bookshelf speakers are the brand's most compact solution, yet still capable of delivering unprecedented performance.
The S Gen2 Obsidian Folded Motion tweeter, Folded Motion waveguide and 5.5" aluminum-membrane bass/midrange driver work together to create a stunning, impressive experience while maintaining a compact footprint.
The Martin Logan Foundation range redefines accessibility by integrating several of Martin Logan's renowned high-performance technologies, all at an affordable price. Drawing on 40 years of design and technical prowess, and offering incredible performance, the Foundation range represents an excellent gateway to the world of HiFi. It's the ideal foundation for a highly efficient stereo or surround sound system.
Martin Logan loudspeakers are renowned for their exceptional articulation, detail and realism, whatever the listening environment. Using advanced driver and controlled dispersion technologies, Martin Logan offers a unique listening experience.
The Gen2 Obsidian Folded Motion tweeter delivers incredible sonic performance, unmatched by conventional technologies. By folding an ultra-thin material, Martin Logan is able to increase the emissive surface area in a small space. Large surface area, low weight and low excursion mean an incredibly fast and responsive tweeter, capable of reproducing the most nuanced content with stunning detail and clarity.
Le waveguide des Martin Logan Foundation B1 assure une parfait contrôle de la dispersion du tweeter, couvrant la zone d'écoute avec des détails et une précision incroyables. Celui-ci évite également les réflexions de la pièce qui nuisent aux performances et fournit un son plus cohérent sur une zone d'écoute plus large.
Using technology from Martin Logan's Motion XT and Motion ranges, the B1s take advantage of the exceptional properties of the aluminum diaphragm to maximize mid-bass driver clarity, detail and efficiency.
