MartinLogan Motion Foundation B2

High-performance sound made affordable

MartinLogan’s Motion Foundation lineup is all about making high-fidelity sound more affordable and accessible. And the company knows how to make a budget-friendly speaker sound great after 40 years of designing speakers. The Motion Foundation B2 is the largest bookshelf speaker in the lineup. It uses driver technologies from MartinLogan’s higher-end designs to deliver rich, precise sound.

Advanced tweeter design with a wide sweet spot

The B2’s high-frequency reproduction is handled by a second-generation Obsidian Folded Motion® tweeter. This advanced tweeter design uses a thin film that’s folded dozens of times like an accordion to give it more surface area without being gigantic. Since it’s made from a thin material, it’s remarkably lightweight and produces very low distortion. What that means in plain terms is that it has a precise, lightning-quick response that can reproduce subtle nuances in your music with lifelike clarity.

The tweeter also features MartinLogan’s latest Folded Motion Waveguide. It widens and directs the tweeter’s dispersion and ensures sonic consistency across the listening area. That means the sound stays clear even if you’re sitting off to the side.

Trickle-down woofer design

The B2 uses a rigid aluminum 6-1/2″ woofer for the mids and bass. Its design is borrowed from MartinLogan’s more expensive Motion and Motion XT series models and refined to deliver detailed lower midrange and upper bass.
