Features

  • The MartinLogan Sound

    Regardless of the environment, MartinLogan speakers achieve high levels of articulation, detail, and realism. Utilizing exotic thin film technologies and Controlled Dispersion, MartinLogan provides unique and special listening experiences not commonly found in the industry.

  • Gen2 Obsidian Folded Motion Tweeter S

    The Gen2 FMT S offers effortless performance, unmatched by conventional technologies. By folding thin film material, MartinLogan can pack more surface area into a small space providing incredible detail and clarity sure to bring your favorite content to life.

  • 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.

  • 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.

  • Aluminium Midrange and Bass Drivers

    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.

  • 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 peak performance.

  • 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.

  • Threaded For Stands

    Threaded inserts on the bottom of the speaker allow for secure attachment to MartinLogan’s matching speaker stand, the STAND25.

    Great!

    Excellent speakers. Very detailed, Great mid-range & decent bass. They are 5 OHM rated that dip into the 3's so you need a good AVR or amp with power to drive them.

  • What is the difference between b1 and b2 regarding sound? The mid bass (?) in the b1 is 5.25 inches and the mid bass (?) in the b2 is 6.25 inches. How does this affect the sound.

    Larger woofer always makes more low end more available as long as the driver is capable. In this case it is. B2 has a very good balance from low to high end, especially in its price range. I've heard both extensively and myself went with the B2. The more range and headroom you give yourself the better.
