MartinLogan Motion 20i, 15i, And 30i Speakers Reviewed

MartinLogan is most popular for its elite execution half breed electrostatic speakers, however those huge boards by and large order a top notch sticker price, to avoid even mentioning their land requests. For as long as decade, however, the organization's Motion arrangement has served to convey something likened to electrostatic execution in more customary cupboards at a more reasonable cost. Also, assuming the accomplishment of the original Motion speakers is any measurement to go by, apparently objective has been extensively met. Not an organization to become complacent, however, MartinLogan has kept on fiddling with driver innovation, bureau plan, and hybrids,

bringing about another Motion Series setup, put aside from their ancestors by the incorporation of an "I" postfix.

Looking back, I'm happy this occurred. The general put-togetherness of these speakers, particularly in red pecan, is definitely past what you would expect at the asking cost.

MartinLogan offers the new Motion line in three completion choices: matte white, shine dark, and red pecan. I'd mentioned a set completed in shine dark, yet no audit units were accessible in that completion for one of the models, so they sent me a set completed in red pecan rather to keep the framework outwardly predictable.

Looking back, I'm happy this occurred. The general quality of these speakers, particularly in red pecan, is clearly past what you would expect at the asking cost.

Yet, the excellence of these cupboards isn't simply shallow. The cupboards include built up inward supporting, with 1.2-inch thick MDF perplexes and 0.7-inch thick MDF dividers, which help to diminish bureau resonances that may somehow or another shading the sound. Doing the exemplary knuckle-wrap against the speakers uncovered a shockingly idle crash.

Tastefully, the new Motion series speakers look similarly as the past age. All speakers highlight a bureau that is two-tone in shading (matte dark belt and your bureau finish of decision), an inclining top plan, back bass ports, and five-way toolless restricting posts. The floorstanders highlight two arrangements of restricting posts for bi-amp or bi-wiring (assuming that is your thing).


For drivers, all ebb and flow age Motion series speakers include a 1-inch by 1.4-inch "Collapsed Motion Transducer," referred to all the more usually as an Air Motion Transformer (AMT). This kind of tweeter utilizes an incredibly low-mass piece of Polyamide, which is just barely gotten like an accordion by strong magnets to deliver high recurrence sounds. MartinLogan claims their cycle of this sort of tweeter is especially quick, proficient, effortlessly controlled for low bending, and offers a high separation point past the frequencies of human hearing. MartinLogan needed a tweeter that could as intently emulate the sort of strong mark their better quality electrostatic speakers produce, and, as indicated by them, this AMT variation tweeter is the following best thing.

To deal with the midrange and low frequencies on the floorstanding and focus channel speakers, MartinLogan utilizes a couple of 5.5-inch aluminum cone woofers, while the shelves use a solitary 5.25-inch aluminum cone woofer. Aluminum was picked due to its intrinsic inflexibility, strength, low weight, and high damping factor, which permits their woofers to all the more flawlessly incorporate with the tweeter. On the floorstanders, MartinLogan has put the auxiliary woofer near the ground to assist ease issues with floor skip.


With an end goal to lessen bending, the woofers presently utilize an inward residue cap. MartinLogan claims this builds up the strength and inflexibility of the cone contrasted with the past age woofers. The encompass and insect backing material for the woofers has been additionally hardened, which, as per MartinLogan, raises the driver's full recurrence over the driver's hybrid point. This implies the result frequencies of the driver stay in its perfect balance.

Talking about which, MartinLogan's plan reasoning for the hybrids utilized in the Motion line can be delegated direct and not excessively intricate. The organization guarantees this direct methodology is conceivable because of their cautious choice of drivers. The restrictive Vojtko hybrid organization utilized offers great capacitors, custom injury inductors, and elements both warm and over-current insurance.

The Hookup

MartinLogan_Motion_20i_rear.jpgThe speakers accompany elastic feet pre-introduced, which means they're prepared out of the case assuming you anticipate utilizing them on a hardwood floor. Discretionary spikes for cover establishments are remembered for the container and can be handily traded out during the unpacking system.

MartinLogan proposes somewhere around 72 hours of break-in. Each of the speakers sent for audit went through a break-in period at the plant, so they were prepared to shake out of the container.

I originally set up the floorstanding 20is in my front room to perceive how they dealt with two-channel music prior to setting up the whole framework in my devoted theater. In my family room, the 20is supplanted a couple of Monitor Audio Gold GX50 speakers, which, incidentally, are estimated equivalent to the 20is. While these two arrangements of speakers aren't really great possibility for correlation purposes (shelves versus floorstanders), they actually made for an intriguing examination. Fueling the speakers was an Onkyo A-9010 coordinated enhancer.

MartinLogan gives astounding arrangement tips in the client manual for these speakers and I propose those new to speaker arrangement read the manual. For my situation, I found that the 20is had a marginally smaller perfect balance than the GX50s, so I returned and changed the speaker's toe-in to get them to sound their best.

In the theater, each of the five Motion speakers were set up in a run of the mill five-channel encompass sound design. As in my family room, I changed the left and right divert 20is for toe-in, to get them to sound their best. MartinLogan was adequately great to send over a couple of their Dynamo X1100 subwoofers to serve bass frequencies in my theater. An audit for these subwoofers will come soon, so I'll hold back to offer any remarks on them. Fueling the Motion speakers in my theater was Denon's AVR-X4500H.

Prior to doing any basic tuning in, I ran a pass of Audyssey MultEQ XT32 through my recipient. Be that as it may, during the altering system for this audit, Dennis Burger let me know about something that's usually kept under wraps. There is a portable application, MultEQ Editor, accessible for both Android and iOS intended to enhance Audyssey, which gives proprietors more granular command over the EQ and sifting process. From now on, for best outcomes, I'll utilize this supplemental programming and we exhort our perusers who own collectors supporting this product to do likewise.

How about we move this present: MartinLogan's "Collapsed Motion" AMT tweeter truly stands apart to me as the characterizing reason one ought to think about these speakers. I'm a sucker for these tweeters, so I might be a piece one-sided. All of the AMT tweeters I've run over share similar apparently intrinsic sonic characteristics. I'd contend that these characteristics are a particularly regular, natural, and smooth show of sound. The sort of tweeter doesn't for the most part toss regard for itself and will in general mix in well with the remainder of a speaker's by and large sonic mark.

For this equivalent explanation, certain individuals contend it's this sort of tweeter's greatest imperfection. Since it doesn't plainly cause to notice the top end, something numerous audiophiles are searching for in a speaker, it doesn't interest them. I'd contend that the tweeter's sonic characteristics clarify the remainder of the speaker too. Sound was reliably smooth and normal, and the 20is were never exhausting, settling on them an incredible decision for the individuals who like to tune in for significant stretches of time. Assuming that you're after something more unmistakable sounding, I don't think these speakers are for you. In any case, on the off chance that you esteem a more easy, regular sounding show, you've come to the ideal locations.

MartinLogan depicts its new Motion Series speakers as having a "wide soundstage" by plan and, in the wake of investing a few energy with these speakers, I need to concur with that evaluation. Particularly contrasted with the GX50s that the 20is supplanted, these MartinLogans make a soundstage observably bigger, regardless of being set up in a similar spot the GX50s once stood, and in spite of having a marginally smaller perfect balance.

Looking back, I'm happy this occurred. The general quality of these speakers, particularly in red pecan, is clearly past what you would expect for the asking price.About seven minutes into the track, the band's piano player, Butch Taylor, starts to lead the pack, with bassist Stefan Lessard and drummer Carter Beauford including their part to adjust the jam. Through the 20is, bass and percussion notes had a lot of essence, while the piano sounded unmistakably sweet and rich smooth, and never cruel as certain speakers can make this instrument sound
