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.
