Our take on the MartinLogan Motion® 35XT

With its flawless high-gloss finish, gently tapered cabinet, and handsome perforated magnetic steel grille, one could be forgiven for mistaking the MartinLogan Motion 35XT as a beautiful piece of furniture. But one listen will tell you this speaker's beauty runs far deeper. As MartinLogan's most potent bookshelf speaker, the 35XT dazzles with its dynamic, impactful, and transparent sound. And as a member of MartinLogan's award-winning Motion® series, this speaker takes advantage of advanced technologies like the Folded Motion™ XT tweeter, sophisticated crossovers, and custom bi-wire binding posts.

Beautiful inside and out

Folded Motion XT tweeter for detailed sound

MartinLogan's innovative Folded Motion XT tweeter uses a pleated diaphragm that works similarly to an accordion by "squeezing" air to create sound. 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 tweeter boasts a 40% larger radiating surface area than that of ML's standard Folded Motion design, for even greater bandwidth and efficiency.

Bass that keeps pace

The Motion 35XT uses a low-distortion 6-1/2" aluminum cone woofer to supply fast, clean midrange and powerful bass performance that blend in seamlessly with the Folded Motion XT tweeter. A low-turbulence rear-firing port extends bass performance, but keeps it tight and tuneful.

Praise for the MartinLogan Motion® 35XT from The Absolute Sound

The sonic character of the 35XT is first and foremost, refined. There is a relaxed quality to the 35XT that takes a natural acoustic recording like Stravinsky's Pulcinella and delivers wind sections and upper strings with sweetness and openness. Transients, low-level resolution, and micro-dynamics are likewise also very good-I always listen for the soft tapping of the keys of the oboe midway through this ballet. The 35XT never missed a cue.

All told, the Motion 35XT offers some stiff competition to battle-hardened rivals like the Sonus faber Venere 1.5 with its espresso midrange, or the Focal Aria 906 with its punchy bass response and all-around dynamism. But of these contenders only the ML has the virtue of its sweet tweet, and offers such a high level of overall transparency and musicality. The 35XT is a worthy heir to the proud tradition at MartinLogan.

Matched these speakers up with my Martin Logan Motion 40s to create a real FULL sound. The 40s sounded great by them selves. Adding the 35xts filled a sound gap I didn't know existed. What a rich full sound with depth.

Product Research


2-Way Bookshelf Loudspeaker: The MartinLogan Motion 35XT bookshelf loudspeaker employs a 2-way speaker design and features MartinLogan's advanced resolution Folded Motion XT tweeter and a single 6.5" aluminum cone midbass woofer. Pairing these two drivers together creates a dynamic full-range sound with an expansive soundstage.

  • Folded Motion Tweeter: MartinLogan's Folded Motion XT tweeter helps give the Motion 35XT bookshelf loudspeaker its natural, realistic high frequency sound. Lightning fast transient response, combined with a large surface area (8x that of a typical 1" dome tweeter) creates clear, dynamic, and precise sound. The 1.25" x 2.4" Folded Motion XT tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90% less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion (80°x30°) to create a realistic and carefully etched sound stage.
  • Aluminum Cone Woofer w/ Bass Port: The MartinLogan Motion 35XT bookshelf loudspeaker features a high-excursion 6.5" aluminum cone woofer with a cast basket housed in a non-resonant asymmetrical chamber with a rear-firing bass port. The aluminum cone woofer uses a rigid structured dust cap to reduce cone break-up and distortion. Pairing the 6.5" woofer with a rear-firing bass port provides higher output and audibly richer, deeper bass performance.

Precision Crossover: To seamlessly blend the audio output from the high frequency driver (tweeter) and the midbass driver (woofer), the Motion 35XT loudspeaker features a precision 2,200Hz crossover utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.

High-Gloss MDF Cabinet: Complementing the Motion 35XT loudspeaker's sonic accuracy is its solidly constructed 3/4" thick MDF cabinet. The cabinet is finished in either high-gloss piano black or black cherrywood, and includes MartinLogan's signature perforated grille. The Motion 35XT speaker's elegant and timeless look will blend into almost any decor. The speaker cabinet also features rounded edges and a gently tapered top.

Bi-Wiring/Bi-Amping: Using the dual posts, you can bi-wire or bi-amp the speaker. Bi-wiring or bi-amping the speaker provides improved bass & treble performance. If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).

  • Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
  • Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.
Note: MartinLogan's proprietary tool-less binding posts simplify cable connection and management. The binding posts will accept bare wire (16- to 10-gauge), pin-connectors, spade-connectors, and banana plugs (single only).

Break-in Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.

Mounting Options: The bookshelf loudspeaker comes with 4 rubber self-adhesive feet to help secure them in place on a flat-surface, prevent slippage, and reduce vibration.  The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM41B, sold separately) can be used to wall mount the speakers.

High quality great sound front speakers [ Glen  Mar 26, 2017 ]
Recommendation of superb sound quality [ peter  Nov 07, 2016 ]
I do have other Martin Logan Speakers and was very satisfied with the quality of construction and sound. [ Eliezer  Aug 12, 2016 ]
Have two of these and am going to use this one for the center channel. [ James  Mar 08, 2016 ]

10 questions already asked

Doesn't sound like a good idea to put the speakers on that stand. Even without the dog, there's a significant risk. [ Michael  Oct 16, 2018 ]
I was looking at same stand,but I felt a little concerned also,though measuring the depth measures 10"acutely I think would work but the Dog it may not be good choice cus it will be top heavy any. I hope this helps Aloha [ Martin  Oct 16, 2018 ]
Mine sit on top of a credenza and a set of small (very short) IsoAcoustic stands. I use the stands not mainly for extra height but in order to tilt the speakers back slightly. No dog problem, but on rare occasions we do have an earthquake here in Southern California, so there is a risk that they'll topple. The speakers come with little rubber feet. You could simply glue those feet to the plate. If at any point you are unhappy with the arrangement the little feet can be peeled off and replaced to serve any new arrangement. No harm to the beautiful speakers. Damn, they are gorgeous and I'm thrilled with the sound. I supplement them with a Martin Logan Dynamo 700 subwoofer. That equipment and a nice glass of Cabernet Sauvignon and I am happy listener. Think I'll go do that now. You sure did pick some fine little speakers! [ joel  Oct 16, 2018 ]
No , you don't need an additional amp to use. They also come with jumpers to wire like a standard speaker. They are outstanding speakers!!! [ Glen  Oct 03, 2017 ]
These speakers do not have wall mount or bracket attachment points. There are four self sticking rubber pads included which attach to the flat bottom surface to control vibration and sliding. I set my speakers on a bookshelf. [ Glen  Apr 07, 2015 ]
I'm pretty sure there's no mounting holes on bottom but I don't recall. You should spend for great quality stands because these speakers deserve it. Unless you're good with woodworking and you can make your own. They sound best with the tweeters at ear level. [ PHILLIP  Apr 07, 2015 ]
Any quality 24 inch stands will work. There are no mounting holes on the bottom. I recommend you invest in high quality stands of 24 inches in height. [ PHILLIP  Apr 07, 2015 ]
No but the speakers are quite loud at full volume and can fill a fairly large space with sound [ WILLIAM  Dec 02, 2014 ]
I forwarded your question to an Advisor and they responded with the following: There isn't a set amount that you should or shouldn't spend. There are a variety of factors that play into what model would best work for you, including tonal preferences you have. To be able to better recommend a product tailored to your preferences I suggest giving an Advisor a call at 1-800-324-9695 or online chat. Thanks! [ Krissy  Nov 05, 2014 ]  Staff
I would take them home and listen. This is your best bet. You can return them if you are not happy. I think you will like them. [ Eliezer  Apr 24, 2018 ]
I actually haven't bought them yet. They do sound better than any speaker for price. I've listened to many. [ Robert  Apr 24, 2018 ]
my experience with the 35xt's is they are efficient but the larger air motion tweeter puts a big load on some amps [marantz 7025] causing them to shut down. i had to unplug it to get it to reset several times - so i think any amp you use with them better have a hefty transformer. [ richard  Dec 28, 2017 ]
These speakers are outstanding to say the least!!! You will not regret your purchase. I love them I think some of the best speakers I've ever owned and not the most expensive. I would highly recommend! [ Glen  Dec 27, 2017 ]
Not sure, however, I have purchased the speakers and love them. I am considering getting a sub-woofer to pair with them for more bass when needed. [ CYNTHIA R  Nov 15, 2016 ]
Not 100% sure - seems a little under powered compared to these excellent ML speakers. I personally use a Hsu Research VTF-15H MK2 and this is awesome [ KEVIN  Nov 15, 2016 ]
No as long as the amp is capable of driving a 4 ohm load without clipping. Check your amps owners manual [ PHILLIP  Jun 24, 2016 ]
That's really a question for the manufacturer, but (as an electrical engineer) I would recommend against it. However, there is probably zero chance of you ever delivering even 100W to these as rear speakers, and probably more like 20W in actuality. Unless you're using these outside, your ears will give out before you get near 300W( or even 100W) actually delivered. [ David  Jun 24, 2016 ]
I would be hesitant to use a 4-ohm speaker with anything that is not rated for 4-ohms. The lower impedance will drive the amp harder, and could result in damaging the receiver. [ Jeff  Nov 05, 2014 ]  Staff
