MartinLogan Motion Foundation F2 Floorstanding Speaker – Each

What You Need to Know

A Real Three-Way Tower at an Approachable Price

The MartinLogan Motion Foundation F2 brings the technology of MartinLogan’s flagship towers—the Folded Motion tweeter, aluminum cone drivers, the McCracken-Vojtko crossover—to a price most listeners can actually reach. Five drivers in a genuine three-way configuration, including three 6.5-inch woofers, deliver full-range sound down to 36Hz with the airy, effortless treble MartinLogan is known for.

Available in Walnut, Gloss Black, or Satin White, and sold individually.

The Gen2 Obsidian Folded Motion Tweeter S

Instead of a conventional dome, MartinLogan pleats a lightweight film diaphragm like an accordion and squeezes air between the folds. The motion required is tiny, distortion is remarkably low, and transient response is lightning fast—the signature MartinLogan clarity that first made the brand famous.

Paired with the Folded Motion Waveguide, the tweeter’s dispersion opens up to a generous 90° by 90°, so the sweet spot follows you around the room rather than pinning you to one chair.

A Dedicated Midrange Makes All the Difference

Most towers near this price are two-way designs that ask a woofer to reproduce vocals while also making bass. The F2 doesn’t compromise: a 5.5-inch aluminum-cone midrange in its own non-resonant chamber handles the heart of the music, crossing over at 330Hz and 3,600Hz.

Voices sound present and uncolored, and instruments keep their body—the payoff of a true three-way.

Three 6.5-Inch Woofers, Tuned for Real Rooms

Three aluminum-cone woofers with unibody construction fire from a non-resonant asymmetrical chamber, rear-ported for output to 36Hz—deep enough that many listeners never add a subwoofer for music. MartinLogan’s Floor Bounce Compensation tunes woofer placement and crossover behavior to work with the room’s floor reflection rather than fight it.

Finished and Detailed Like a Costlier Speaker

Each finish gets its own trim treatment—silver, bronze, or gunmetal accents around the drivers—and Secure-Lock grilles mount with stealth tabs that let you run them on, off, or rotated to align the fabric grain. Adjustable spikes level the speaker on carpet, with rubber feet included to protect hard floors.

Building Your System

At 92dB sensitivity and 4 ohms nominal, the F2 is an easy load for any decent amplifier or receiver from 15 to 200 watts. Connection is via a single pair of 5-way binding posts.

For home theater, match it with the Motion Foundation C1 center and B1 or B2 bookshelf speakers, and add a MartinLogan Dynamo Foundation subwoofer for the lowest effects. Backed by a 5-year parts and labor warranty with registration.

Frequently Asked Questions

Are these sold in pairs?
Each F2 is priced and sold individually, so order two for stereo—or add matching Foundation models to build a full home theater.

How does it compare to the Motion Foundation F1?
The F1 shares the same tweeter and midrange but uses three 5.5-inch woofers in a smaller cabinet. The F2’s three 6.5-inch woofers move more air, extending bass from 41Hz to 36Hz—the better choice for medium and larger rooms.

How does it compare to the Motion XT F100?
The XT F100 steps up to MartinLogan’s larger Folded Motion XT tweeter, a Nomex-reinforced Kevlar midrange, cast-aluminum driver baskets, bottom-firing ports, and bi-wire terminals. The Foundation F2 delivers the family sound and a true three-way layout for less than half the price.

Do I need a subwoofer?
For music, often not—36Hz covers most of what’s on a record. For movie effects, a MartinLogan Dynamo Foundation subwoofer fills in the bottom octave.
