Martin Logan Motion Foundation B1: Small in size but not in sound

The Martin Logan Motion Foundation B1 bookshelf speakers are the brand's most compact yet yet deliver unprecedented performance.

The S Gen2 Obsidian Folded Motion tweeter, Folded Motion waveguide, and 5.5-inch aluminum diaphragm midrange/woofer work together to create a stunning, immersive experience while remaining compact.

The Martin Logan Foundation range redefines accessibility by bringing together several of Martin Logan's renowned high-performance technologies, all at an affordable price. Drawing on 40 years of design and engineering expertise and delivering incredible performance, the Foundation Series is the perfect gateway to the world of HiFi. It is the ideal basis for a high-performance stereo or surround sound system.

Martin Logan loudspeakers are renowned for their exceptional articulation, detail and realism, no matter the listening environment. Using advanced driver technology and controlled dispersion, Martin Logan offers a unique listening experience.

The Martin Logan Foundation B1 waveguide provides superior control of tweeter dispersion, covering the listening area with detail and incredible precision. It also prevents reflections that interfere with playback and provides more harmonious sound over a wider audible zone.

The Gen2 Obsidian Folded Motion tweeter delivers incredible audio performance unmatched by traditional technologies. By folding the ultra-thin material, Martin Logan was able to increase the radiating surface area in a small space. The large surface area, low weight and low excursion mean an incredibly fast and responsive tweeter, capable of reproducing the finest nuances with stunning detail and clarity.

Using technology from Martin Logan's Motion XT and Motion ranges, the B1 utilizes the exceptional properties of an aluminum diaphragm to achieve maximum midwoofer clarity, detail and efficiency.
