MartinLogan Motion XT F100 Floorstanding Speaker - Walnut - Each

A Bigger Folded Motion Tweeter for MartinLogan's XT Line

The MartinLogan Motion XT F100 is a 3-way, bottom-ported floorstanding speaker with a Gen2 Obsidian Folded Motion XT tweeter — 40% more diaphragm area than the standard Motion Series tweeter — over a 6.5-inch Kevlar midrange and three 6.5-inch aluminum woofers.

MartinLogan rates sensitivity at 92 dB into a nominal 4 ohms, and recommends 20 to 450 watts of amplifier power — a wide enough window to suit anything from a modest integrated amplifier to genuine separates.

The cabinet is available in Gloss Black, Walnut, or Satin White, and sold each, so a stereo pair is two — order one to match an existing speaker, or a matching pair to start fresh.

Where the XT Tweeter Earns Its Keep

A Larger Motor, a Tougher Midrange Cone

The Gen2 Obsidian Folded Motion XT tweeter steps up to a 12.4-square-inch diaphragm and a larger motor structure than the standard Motion Series tweeter, for higher output and lower distortion, crossing over at 2,600 Hz to a 6.5-inch Nomex-reinforced Kevlar midrange.

Three 6.5-inch aluminum woofers, crossing over at 280 Hz, share the bass load below the midrange in a cabinet built to carry real low-end without straining the tweeter or midrange above it.

The Numbers, and What They Ask of Your Amplifier

MartinLogan quotes a frequency range of 31 Hz to 25 kHz within 3 dB. Sensitivity is 92 dB, nominal impedance is 4 ohms (compatible with 4, 6, or 8-ohm-rated amplifiers), and MartinLogan recommends 20 to 450 watts of amplifier power.

A pair of custom 5-way binding posts is bi-wire and passive bi-amp capable; MartinLogan's own manual advises against active bi-amping, since the internal crossover can't be bypassed and doing so seriously degrades performance.

What Reviewers Are Saying

Jim Milton, Secrets of Home Theater and High Fidelity, wrote that "the MartinLogan Motion XT F100 Tower Speakers deliver fantastic performance for far less than the competition," calling them "highly recommended."

Matthew Poes, Audioholics, measured the F100 and called the bass "a sonic virtuoso," despite some tweeter resonance his measurements turned up at the top of the audible range. Audioholics separately named the F100 its 2023 Best Mid Price Tower Speaker.

Who Is This Floorstanding Speaker Best For?

• You want an award-winning tower at this price — Audioholics named the F100 its 2023 Best Mid Price Tower Speaker
• You want MartinLogan's larger XT tweeter and Kevlar midrange — a genuine step up in driver hardware from the standard Motion Series, not just a badge change
• You want a floorstander that's easy to place — the downward-firing port lets the F100 sit closer to a wall than a rear-ported design would allow
• You want one speaker per cabinet, priced and shipped that way — the F100 is sold each, so order two for a stereo pair
• You want real floorstanding bass without a separate subwoofer — the F100 reaches to 31 Hz within 3 dB on its own. For the deepest home-theater effects, add one of our subwoofers and let the towers do what they do best

How Does It Connect to Your System?

Set the cabinet on its F.A.S.T. outrigger feet and use the tool-less height adjustment to level it on any floor. A pair of custom 5-way binding posts accepts a single-wire or passive bi-wire connection.

Give the drivers time to settle; aluminum and Kevlar cones can take some hours of playback before they loosen up fully.

Two cables, two speakers, and you are listening.

Pairs Well With

What finishes the system around a pair of Motion XT F100 towers:

• Integrated amplifiers — 20 to 450 watts into 4 ohms is the window MartinLogan gives
• Stereo amplifiers — a separate power amp if you want more headroom
• Speaker cables — the F100 is bi-wire capable, so a bi-wire run is an option here
• Speaker isolation feet — an alternative to the F.A.S.T. outrigger feet on a wood or tile floor

Frequently Asked Questions

Is the price for one speaker or a pair?

One. The F100 is sold each, so order two for a stereo pair, or one to match an existing speaker.

What comes in the box?

The speaker, its magnetic grille, F.A.S.T. outrigger feet pre-installed with tool-less height adjustment, and the owner's manual.

What amplifier do I need?

MartinLogan recommends 20 to 450 watts into 4 ohms. At 92 dB sensitivity, a quality integrated amplifier drives it well.

Can I bi-wire the F100?

Yes, with a passive bi-wire or bi-amp connection. MartinLogan advises against active bi-amping, since the internal crossover can't be bypassed.

What's the difference between the XT F100 and the XT F200?

The XT F200 steps up to three 8-inch woofers instead of 6.5-inch, in a taller cabinet with deeper bass extension and more amplifier headroom, at a higher price.

What finishes are available?

Gloss Black, Walnut, and Satin White.
