The Motion F20 is a floorstanding loudspeaker from MartinLogan's Motion range, built with a demanding low impedance and wide power tolerance. This model extends the Motion range's dynamic-driver engineering into genuine tower scale, offering MartinLogan's more conventional driver technology in a full-range floorstanding format.

Key specs that matter

Rated response is 35 Hz to 25 000 Hz. Sensitivity is 92 dB into a demanding 4 ohm load with an exceptionally wide 20-300 W recommended window. At 112.7 x 29.8 x 36.2 cm and 27.2 kg it is a substantial tower, consistent with the high sensitivity and considerable bass extension this model represents.

Sound and use context

Expect a dynamic, high-headroom presentation given the exceptional 92 dB sensitivity and wide power tolerance - a capable performer reflecting MartinLogan's broader engineering ambition applied to a conventional dynamic-driver floorstanding format.

Pairing

The 92 dB sensitivity and wide 20-300 W window admit both modest and extremely powerful amplifiers, broadening the amplifier choices available for this substantial tower.

Alternatives

MartinLogan's Motion Foundation F1 sits within the same broader Motion range as a somewhat more compact alternative, worth comparing directly on cabinet scale and bass extension before choosing between these positioned MartinLogan floorstanding options. A rigid, well-positioned base also helps this substantial tower deliver its full potential in a given room. Overall this remains a capable floorstanding choice within MartinLogan Motion catalogue. A subwoofer should rarely be needed given this tower already substantial bass extension for most rooms. A dealer visit remains the simplest way to compare current pricing across MartinLogan Motion floorstanding lineup. Toe-in adjustment at the listening seat remains a free tweak worth trying once placement is settled. A dealer demonstration remains worthwhile before purchase.
