MartinLogan Motion Foundation F2 Floorstanding Speaker - Black - Each

A Bigger Woofer Section for MartinLogan's Foundation Line

The MartinLogan Motion Foundation F2 is a 3-way floorstanding speaker with a Gen2 Obsidian Folded Motion tweeter over a 5.5-inch aluminum midrange and three 6.5-inch aluminum woofers, in a taller rear-ported cabinet than the entry Foundation F1.

MartinLogan rates sensitivity at 92 dB into a nominal 4 ohms, and recommends 15 to 200 watts of amplifier power — the same easy-to-drive window as the F1, despite the bigger woofers.

The cabinet is available in 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 a system from scratch.

Where the Bigger Woofers Earn Their Keep

The Same Tweeter, a Larger Bass Section

The Gen2 Obsidian Folded Motion tweeter, identical to the one used on the F1, crosses over at 3,600 Hz to a 5.5-inch aluminum midrange in its own sealed chamber, unchanged from the smaller model.

Three 6.5-inch aluminum woofers, crossing over at 330 Hz, replace the F1's smaller 5.5-inch woofers with more cone area for deeper bass in a room that can take the taller cabinet.

The Numbers, and What They Ask of Your Amplifier

MartinLogan quotes a frequency range of 36 Hz to 23 kHz within 3 dB. Sensitivity is 92 dB, nominal impedance is 4 ohms, and MartinLogan recommends 15 to 200 watts of amplifier power.

A single pair of 5-way binding posts accepts banana plugs, spades, or bare wire, wired straight through to each driver without a separate bi-wire path. A rear-firing port completes the cabinet, so give it the same clearance the F1 needs.

What Reviewers Are Saying

Jerry Del Colliano, FutureAudiophile, wrote that "at 92 dB sensitivity, you can drive the MartinLogan Motion Foundation F2 from a small-to-modest tube amp, a mainstream AV receiver or basically whatever power amplifier that you like or can afford."

His verdict: "few speakers in this competitive price category sound better," with one placement note — keep the rear-ported cabinet clear of the back wall, since sitting too close "can sound a little boomy or bass-heavy."

Who Is This Floorstanding Speaker Best For?

• You want the flagship of MartinLogan's Foundation line — the same Folded Motion tweeter as the F1, with three 6.5-inch woofers for deeper, more effortless bass
• You have the room for a taller cabinet — the F2 stands about three inches taller than the F1, with the bass extension to match
• Your amplifier is modest — 92 dB sensitivity and a 15 to 200 watt window mean a quality integrated amplifier is all it needs
• You want one speaker per cabinet, priced and shipped that way — the F2 is sold each, so order two for a stereo pair
• You want real floorstanding bass without a separate subwoofer — the F2 reaches to 36 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?

Give the cabinet room to breathe — FutureAudiophile's own review found the F2 can sound boomy if placed too close to the back wall. Each cabinet has a single pair of 5-way binding posts for banana plugs, spades, or bare wire.

Give the drivers time to settle; aluminum 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 Foundation F2 towers:

• Integrated amplifiers — 15 to 200 watts into 4 ohms is the window MartinLogan gives
• Stereo amplifiers — a separate power amp if you want more headroom
• Speaker cables — single-wire runs, since this model has no bi-wire terminal
• Speaker isolation feet — a firm footing on a wood or tile floor

Frequently Asked Questions

Is the price for one speaker or a pair?

One. The F2 is sold each, so order two for a stereo pair, or one to match an existing speaker.

What comes in the box?

The speaker with its magnetic grille attached, and the owner's manual.

What amplifier do I need?

MartinLogan recommends 15 to 200 watts into 4 ohms. At 92 dB sensitivity, a quality integrated amplifier is enough to drive it well.

Can I bi-wire the F2?

Each cabinet has a single pair of 5-way binding posts; MartinLogan does not offer a bi-wire terminal on this model.

Where should I place the F2 in my room?

Give it some clearance from the back wall — a reviewer found that placing it too close can make the bass sound boomy, since the cabinet is rear-ported.

What finishes are available?

Black, Walnut, and Satin White.
