MartinLogan Motion® XT F100

A robust Motion XT tower speaker

The MartinLogan Motion XT F100 exhibits some impressive qualities: detailed highs, open and authentic midrange performance, and deep, musical bass response. Like the other speakers in the Motion XT lineup, it features carefully chosen drivers, an acoustically optimized cabinet, and intelligently designed crossovers. It’s an elegant, refined speaker that looks and sounds like a work of art.

Upgraded Motion XT® tweeter

MartinLogan’s acclaimed Folded Motion XT tweeter uses a pleated diaphragm that works similarly to an accordion by “squeezing” air to create sound. The F100’s upgraded Gen2 Obsidian version of this tweeter uses larger magnets for greater detail and accuracy. The new design places it inside a custom Folded Motion waveguide that enhances dispersion of high-frequency sound throughout your listening area.

Because it requires almost 90% less excursion than the typical 1″ dome tweeter, response time is drastically reduced along with distortion. The diaphragm’s increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage. Music sounds amazingly detailed, but smooth and effortless, without a trace of harshness. And the “XT” version of this tweeter that gives the Motion XT series part of its name boasts a 40% larger radiating surface area than MartinLogan’s standard Folded Motion design, for even greater bandwidth and efficiency.

Excellent midrange and bass

The F100 boasts a 6-1/2″ Nomex-reinforced Kevlar® cone woofer for fast, clean midrange. The bottom end is anchored by three 6-1/2″ aluminum woofers that deliver powerful, musical bass performance. A bottom-firing port offers extended bass response that’s also tight and tuneful. And the cabinet features new anti-vibration F.A.S.T. feet that can be installed and adjusted by hand.

Unique crossover network

MartinLogan’s proprietary Vojtko™ crossovers are named after MartinLogan’s chief audio technologist, Joe Vojtko. The latest Motion XT speakers feature upgraded McCracken-Vojtko crossovers, so named for the influence of the company’s other well-known Joe — senior loudspeaker designer Joe McCracken.

No matter what they’re called, the aim is always the same: each speaker’s drivers are carefully selected or designed to operate within an intentional frequency range and specific performance parameters. That allows the crossover networks — built from high-quality capacitors and resistors — to be clean and uncomplicated, for purer sound.
