MartinLogan Motion 60XT vs Yamaha NS-F901 Speakers
I love an old-fashioned shootout, and after the introduction of the Yamaha NS-F901 tower speakers, it seemed like a good idea to do an objective comparison of them to another favorite, the MartinLogan Motion 60XT with Folded Motion tweeter. Both speakers retail for more than your average tower, but still come in as value products compared to what you can find in true “cost-no-object” audiophile listening rooms. We’ll start off by comparing the MartinLogan Motion 60XT vs Yamaha NS-F901 Speakers – looking at both features and design. Next, I’ll post a table outlining the primary differences between the two models (highlighting specs and features in particular). This birds-eye view of both the MartinLogan Motion 60XT towers and the flagship Yamaha NS-F901 floor standing speakers should help you as you decide which might be best for you.
MartinLogan Motion 60XT Speakers
Without waiting at the starting gate, MartinLogan’s 60XT speakers stun us with a street price of just under $3000/pair. Considering these are speakers that dip down to 35Hz (±3dB) and have a wide 80º dispersion (30º vertical), you’re talking about a system that is very easy to place within a room and achieve a nice, wide soundstage. These speakers are also very easy to drive. With a sensitivity rating of 94 dB @ 1W/meter you can connect them up to just about any amplifier (starting at just 20 Watts) and get tons of volume. The thing is, however, with a 4-ohm nominal load and the use of the Folded Motion tweeter, these speakers have a delicate finesse in the high and mid-ranges that is quite unique—and perfect for both classical and jazz music.
MartinLogan Motion 60XT Build Quality, Crossovers, and Drivers
Taking a look at the drivers on the 60XTs you see that MartinLogan wanted to deliver a lot of clean output. Highs are, of course, taken care of by the Folded Motion tweeter, but what’s impressive about that driver is that it crams over 12 square inches of diaphragm surface area into a space measuring just 1.25″ x 2.4″. It’s also fitted with thermal/current protection (which you’ll likely never need to worry about due to the efficiency of the system). The mids are handled by a 6-1/2” aluminum cone woofer with cast polymer basket that is in a sealed chamber. Lastly, the low frequency drivers, that take you down to 35Hz come from a pair of 8” (yes, 8″!) aluminum cone drivers that are seated on cast aluminum baskets. These woofers are positioned within a dual-ported chamber that is asymmetrical to avoid resonance and modes at critical frequencies.
But drivers aren’t everything. The MartinLogan 60XT towers are a three-way design, with crossovers at 400Hz and 2,200 Hz. The crossovers use custom air core coil and low DCR steel laminate inductors along with polypropylene film capacitors (in series) and low DF electrolytic capacitors (in parallel). Even the 5-way bi-wire binding posts are custom and exude an elegance that isn’t to be missed.
Yamaha Soavo NS-F901 Speakers
When you look at Yamaha’s approach to their flagship speaker you see something familiar. The Soavo NS-901 speaker, in our opinion, looks like it could have been made in the same location as one of Yamaha’s grand pianos. The design is clean—almost hygienic, with the white drivers even coming across as too beautiful to touch. The Soavo speakers continue Yamaha’s “natural sound” design where speaker and instrument mesh to become a single device for the advantage of the listener. Given the components placed within the speaker and the specs it delivers, we’re of the opinion that Yamaha makes good on their promises.

To start things off, Yamaha utilized a brand new A-PMD midrange driver. This is an “Advanced Polymer-injected Mica Diaphragm” design that uses an improved cone paper that is light and stiff (two key ingredients in a successful cone material) and doesn’t resonate like aluminum. The key sonic takeaways are a smooth, quick responsiveness that’s nimble enough to handle any type of demanding program material. This new A-PMD driver also implements a rather large neodymium magnet along with an aluminum die cast frame. I am a midrange aficionado and Yamaha has the goods to handle those critical female vocals, sax and acoustic guitar that often get lost with sloppier driver systems.
The offer uses the same A-PMD design so you don’t lose articulation down low where it counts and a 1″ aluminum dome tweeter (also with a neodymium magnet) uses a thick surround material to firmly integrate the diaphragm and voice coil to blend with the midrange driver. The result is a nice transition that is seamless and detailed from the highs through the bottom end (which goes sown to an impressive 32Hz). A heavy aluminum die cast tweeter plate also minimizes resonances and Yamaha implemented a fine mesh grill to aid in dispersion.
The crossovers use Solen metalized polypropylene capacitors as well as iron-core coils (assembled with quality-controlled wire). Each of the parts is directly soldered individually (no printed circuit boards are used), and each cabinet is tuned to ensure the drivers exhibit a smooth transition from top to bottom as designed.
The cabinet (which is available in piano black or white) rounds everyone out with a unique design that uses zero parallel surfaces—all but eliminating internal resonances. The joints are made using a three-way mitered construction, and the woofer and midrange are separated by slanted partition. There’s plenty of vertical bracing, and the entire design (courtesy of Toshiyuki Kita) is one of elegance and poise.
Fine Speaker and Electronics “Pairings”
Like with any fine audio “tasting”, we want to pair these speakers with the right components to make them sing. One of the best amplifiers you’ll want to match up with either the MartinLogan 60XT or Yamaha NS-F901 towers is the Yamaha A-S3000 integrated stereo amplifier. This amp puts out 150 Watts per channel into 4-ohm loads and features, among other things, a hefty direct-draw toroidal transformer and a comprehensive low impedance design. The signal paths have been deliberately designed to eliminate unwanted wiring, and a copper-plated chassis helps reject noise and interference. This thing is a tank of an amp, with a 1/4″ thick aluminum top panel and a symmetrical layout for the independent pre amp and power amp blocks. The amp is constructed with floating and balanced MOSFET-driven power amplifier.
Of course, you also get an electronic volume control and a discrete phono amp, plus oversized VU meters right on front to let you know what your music is up to.
