高级性能
表达式ESL 13A是音频的巧妙呈现,专注于强化您的情绪体验。采用13英寸(CLS™)XStat™静电传感器,双10英寸PoweredForce Forward™低音扬声器,由双300瓦D类放大器供电,由24位Vojtko™DSP引擎和ARC™控制(Anthem Room)更正)。
音频既真实又想象。有声音的事实。并且有一种感觉,声音在我们内部唤起。
这种感觉是新型Expression ESL 13A的灵感来源。就像表现主义的杰作一样,这种巧妙的音频表现只是为了加强你的情感体验。它是一种几乎透明的音频性能,可将您带入感官的新景观。
Expression ESL 13A是Masterpiece系列的一部分。它具有双10英寸低音扬声器系统,具有ARC珩磨性能,可实现完美混合的低频响应。这款低音扬声器阵列与MartinLogan标志性的13英寸宽XStat CLS传感器相结合,再加上强大的双放大器部分,可提供富有表现力的动态音频体验,色彩更少。它揭示了音频的纯粹情感影响。
看看经典的MartinLogan静电扬声器中熟悉的元素:先进的MicroPerf定子技术,它允许暴露的静电膜片表面几乎是相同尺寸的传统静电面板的两倍。该面板采用刚性ClearSpar™垫片加固,可在真空粘合膜片上保持精确的张力水平,而不会遮挡美观的透视设计。添加新AirFrame™ 刀片结构的细长尖箭头设计;一种强大的令人回味的组合,在面板和低音扬声器柜之间创造了一种和谐的连接。
现在注意一些根本性的改进:受我们自己突破性设计的启发,我们重新设计了Expression ESL 13A低音扬声器部分,由新的双300瓦D类放大器驱动,并由24位Vojtko™DSP引擎和ARC™控制( Anthem Room Correction)。
独立的PowerForce Forward™低音对准技术在独立封闭的紧凑型腔室中使用两个10英寸激光设计的低失真铝制锥形低音扬声器,控制后置发声低音扬声器与低音扬声器后面墙壁之间的相互作用。通过智能相移逻辑,我们可以最大限度地减少墙壁对可能反弹回听音室的低音信息的影响。这种均匀的频率响应可以产生逼真的低音效果。这是MartinLogan创新改善您在任何房间的聆听体验的另一种方式。
在实验室中,MartinLogan工程师力求提高透明度。在实验室外,有一张我们的工程师无法解释的通配符:你的听音室。您的聆听空间的独特尺寸和形状(以及其内容的大小和形状)可以使低音波做出不可预测的事情,极大地影响了扬声器的整体性能。
Expression ESL 13A集成了独家的Anthem室内校正(ARC)技术。通过使用ARC来控制与ESL面板输出相关的低频曲线(如此图所示),您将体验与MartinLogan音频测试实验室相同的性能。
ARC测量您房间内的低频声音输出,并将其与最佳响应曲线进行比较,以反映空间异常。 ARC的先进算法可以有效地消除异常现象,只留下理想的标准:在您的聆听空间中实际融合,自然发声的低音表现。
通过最大限度地减少房间与PoweredForce Forward低音技术的交互和ARC的高级房间校正功能,以及其独特的ESL和低音部分合成,Expression ESL 13A可产生完美蚀刻的成像和聚焦;栩栩如生的聆听水平的声音的最佳自然再现;并且在户外进行灵活,全方位的操作。
很明显,正是这种极致性能水平将仅仅优秀与真正的杰作区分开来。
Expression ESL 13A XStat面板采用MartinLogan重新设计的AirFrame Blade结构连接到扬声器音箱,采用航空航天级挤压铝合金精密制造。这种材料和这种独特的制造工艺使得面板非常坚固。
这款AirFrame Blade导轨系统采用醒目,前卫的造型设计,前部窄而强,侧面宽而有力,是一种现代设计风格。它绝不会妨碍可播放的表面区域或干扰面板的偶极声辐射模式。它还提供电气和声学隔离,最大限度地减少由振动和共振引起的互调失真。流畅的线条突出了面板本身与紧凑的低音扬声器和放大器部分的突破性整合。令人叹为观止的AirFrame Blade设计增强了成像,低级声音细节,精确度和扬声器效率。
CLS技术是我们生产的每个静电扬声器的重要组成部分。通过我们专有的制造方法,我们内置了面板的柔和水平曲率。这种独特的设计增强了大型辐射表面产生的高频细节,同时不影响整体音质。请注意柔和的现代曲线和穿孔图案如何让位于低音扬声器部分的扁平格栅。
我们从扬声器听到的声音是从它到耳朵的直接辐射,以及房间表面 - 墙壁,地板和天花板的反射。我们的大脑如何整合这些信息远非简单。根据耳朵的入射角度和直接声音与反射声音之间的到达时间差异,反射可以模糊细节和立体声成像,或增强深度和开放性的自然印象。
静电面板是真正的偶极扬声器,可产生几乎理想的受控色散辐射图案。它们向侧面发出非常小的声音,从而最大限度地减少侧壁反射,其短暂到达时间往往会干扰直接声音的感知。然而,它们强大的后向辐射产生了大量自然的,充满氛围的后来到达的中上注册信息。
PoweredForce Forward低音技术结合了两项MartinLogan音频创新:PowerForce,可以让小型音箱准确地产生大量的低音,ForceForward可以显着降低性能,从而消除前壁低音反射。
PoweredForce Forward低音技术采用先进的分频拓扑结构,具有相位定时低音扬声器,可最大限度地减少破坏性反射能量。通过几乎消除前壁低音反射并与面板协同工作,PoweredForce Forward Bass技术为您提供更多的放置灵活性,并增强声源的真实音频真实感。
Masterpiece系列音箱的深度经过精心挑选,以最大限度地发挥PowerForce和ForceForward技术的优势,提供极致细节的强劲低音。结合Anthem Room Correction(ARC™) ,这些先进的低音技术提供了一种真正独特的低频精度。
Masterpiece系列扬声器箱体尺寸在其Forofof低音扬声器系统中创造了低音扬声器,音箱体积和放大器之间的理想关系。通过为低音扬声器提供充足的内部音量(两个密封音箱 - 每个低音扬声器一个)以及强大的放大功能,带有动力低音扬声器系统的Masterpiece系列音箱能够在保留低音细节的同时达到最低音量。
采用ForceForward低音技术,低音扬声器相互之间的距离越远,频率越低,其有益效果就越大 。 MartinLogan的ForceForward技术解决了一个问题(几乎在所有扬声器中都有),低音频率的声波在扬声器后面的墙壁上反射,并与向听众传播的波浪相互作用。当这些相互作用到达你的耳朵时,这些相互作用会在这些频率中产生非线性,并且低音信息会受到与原始声音不准确的取消和过度的影响。通过选择性地调整其相对低音扬声器输出的相位,动力Masterpiece系列扬声器消除了扬声器后面有问题的低音能量。
ForceForward还通过消除扬声器后面的低音能量并创建均匀的低音发射,简化了扬声器放置的任务。这使得Masterpiece系列扬声器音箱比前几代MartinLogan音箱更接近墙壁。根据经验,我们建议将扬声器箱的后部放置在比其低音扬声器直径更近的位置(Renaissance ESL 15A:12英寸,Expression ESL 13A:10英寸,Impression ESL 11A和Classic ESL 9) :8英寸)。为了增加控制水平,Masterpiece系列扬声器采用了两级控制(75Hz和200Hz),可以对低音集成进行微调。
此外,由于它们具有偶极性质,静电面板在距离墙壁至少2.5英尺或更远的位置时表现最佳 - 这种距离对于几乎任何高端扬声器的前端都是理想的,无论驱动技术如何。 Masterpiece系列机柜的深度使其能够提供与墙壁保持足够距离的静电面板,从而保证了非常详细的三维立体声。
使用5向发烧友WBT接线柱安全可靠地连接电子设备。它们的纯铜连接板具有高导电性,并且没有“涡流”效应。这些接头是绝缘的,可以防震,并且完全阻尼振动。它们为大型专业扬声器连接提供了充足的空间。
Expression ESL 13A的表现已经从头开始重新考虑。充分利用PoweredForce Forward和ARC Technology等创新技术,以及静电面板与低音扬声器阵列的集成,需要大胆考虑功率和效率。我们新推出的双300瓦功率放大器可在比空前更小的空间内提供清洁电源。它们可以轻松地提供令人振奋的动态影响,并且可以节省大量开销。卓越,可靠的D类技术意味着放大器和低音扬声器之间几乎没有能量损失。
Vojtko Voiced是Expression ESL 13A中的高级分频器和电子元件,为这款巧妙的构图增添了中等清晰度。这款分频器采用最精细的聚丙烯电容器和空心线圈精心手工制造,采用了MartinLogan专有的Vojtko拓扑结构,可实现极低失真和无缝驱动器/ ESL集成。这种精确调整的网络可以保留最微小的声音细微差别,同时处理任何信号源的完整动态。
我们还考虑了您将为扬声器供电的信号,并设计了Expression ESL 13A,以便与几乎任何类型的电子设备配合使用。 MartinLogan最先进的环形变压器和电气接口工程确保了从放大器到静电面板和低音扬声器阵列的绝对透明连接。这产生了无与伦比的纯度,精确度,清晰度和开放性的声音 - 对于没有扬声器的下一个最好的事情。

"The MartinLogan Expression 13A are the kind of speakers you can easily forget. That is a high compliment for a speaker review. Once in place and supported by proper room treatment, and perhaps a little room correction for ultimate smoothness and ideal SS&I - don't forget about the optional ARC correction built in - I predict most listeners will quickly become comfortable with the inability to find the 13A in the room - they can disappear that completely - and become completely sonically unobtrusive in their systems. The Expression 13A are another example of Electrostatic Magic from the Electrostatic Wizards at MartinLogan. I highly recommend them."—Wayne Myers, AVNirvana.com

I recently upgraded from the Summit X to the Expression ESL 13A in my media room (previously I had also updated from the Stage X to the Focus center channel several months earlier). This time around I got a custom color instead of a standard finish to closer match my Focus center channel. First let me comment on the quality of the finishing, packaging and workmanship. I saw all this and more first hand at a visit to the Canadian plant so I was not surprised but it was all very well done. Also now that I have purchased several ML products over the years (Summit X, Descent I’s, 212's, CLX Art, Focus, Vanquish) the packing is very good and they have all arrived in great condition. I know packaging is probably not the most talked about topic but we do want our product delivered in good condition. Believe me it’s no accident that they do it’s that good. I must admit I was not an immediate fan of the new look compared to the Summit X's that I had at the time. I was not able to see anything in person until a couple of years ago at Axpona where a pair of 15A's were on display. What I saw on line the new ones just seemed to industrial looking. The much bigger boxy lower end seemed so much bigger then past designs so I was concerned that visually I would not like them as much as the Summit X's. Well let me tell you once I saw them in person I was much impressed with the new design, the much beefier frame and particularly the sound. Being familiar with ML speakers I came to love the clarity of the sound and the new 13A’s just make you smile so much more. The wider panel helps, the much sturdier frame helps but probably the biggest improvement is in the bass section. Yes it’s larger but its sooooo much better. Most likely a combination of the improved amp, the actual enclosure and the calibration software. I was first introduced to the calibration software with my purchase of a couple of 212 subs. It made a tremendous difference in how the bass played in my room and I was not disappointed in how after calibration the bass on the 13A’s sounded – tight, deep and fast just how I like it. I also believe the integration with the top panel is even better with the 13A’s as compared to the Summit X’s. That is saying a lot as I thought the Summit X’s were very well integrated but the new ones are even better. My setup is multichannel not two channel like my Summit X’s were before being moved into the media room. So I don’t have much experience on two channel performance but my gut tells me they will perform nicely and better then the Summit X’s. All I can say to the ML development team is you have hit it out of the park with the new lineup. It was a tough thing to accomplish but it’s nicely done – Visually and Sonically. Not just a small incremental improvement but justifying the new models as they are aptly named.
Martin Logan Trainer & Set-Up Expert Joel Lopez - "It's My Passion"
My wife and I purchased Martin Logan Expression 13A loudspeakers from the Magnolia Audio & Design Center in Madison, Wisconsin.
Nick Hufford the store manager put me in contact with Joel Lopez at Martin Logan regarding questions I had about rake angle and set up.
My first contact was in March of this year.
I had already seen several YouTube videos with Mr. Lopez about setting the speakers up.
I sent to Mr. Lopez an email containing material from the Cardas website regarding speaker set up.
Their calculator was the most helpful.
Thank you for contacting Cardas Audio.
I recommend using the standard calculator to start. This will help to maximize bass performance. If you also mark the spot for the dipole calculator you could try any location between the two to improve imaging also.
Imagine my surprise when there was a message on my cell phone from Mr. Lopez offering to speak to me via telephone regarding my questions and concerns. In the course of that conversation Mr. Lopez offered to come to our home to personally set the speakers up and implement the Anthem Room Correction, a program built into these speakers designed to take the room out of the equation; identifying and removing room nodes and standing waves; essentially allowing the speakers to perform at their best without being compromised by interaction with anomalies caused by the room. Frankly, I was flabbergasted by his offer.
He wrote back after reviewing the numbers: When looking at the calculator it looks as though his calculations are correct and also what we would recommend as well.
The only downside with using technology for speaker placement is it doesn't take into account things like type of flooring, thickness of sheetrock, type of paint weather flat or gloss, and objects in your room that will absorb or diffuse sound waves. My personal suggestion would be to use the calculator as a starting point for placement but be aware that minor adjustments in placement and or toe in can have a big effect on your overall sound.
My offer still stands to come to your home and insure your speakers are performing to the reference level we intended.
I simply could not believe my ears. This was personalized service unlike anything I had read about in the industry other than knowing about Peter McGrath of Wilson Audio going to the home of a customer after a sale to set up speakers and of course dealer set up.
The set up team from Magnolia did an outstanding job using the results generated by the Cardas calculations.
Even before the speakers had 100 hours on them it was hard to imagine how much better the response could be even though I had read reviews which testified to the difference the ARC made.
Moreover Mr. Lopez sent instructions for achieving a rake angle of one degree (almost exactly perpendicular to the floor) something I desired, to improve imaging even further so I would have them to give to the install team.
He added “Once I get a chance to travel back to Madison, your speakers will have played for the recommended break in period and I can then lend my expertise by making adjustments in placement to squeeze out every ounce of performance as possible.”
Mr. Lopez came to our home on July 25th and I played for him 9 selections from vinyl, several from Redbook CD’s and two from an SACD so he would get a good feel for how our system sounded before he started.
I thought, somewhat pridefully, that the system sounded very good but was looking forward to witnessing to what degree it could be improved.
He felt the soundstage was too small and went to work knowing that my priority, if I had to choose between a large soundstage versus focus, I would choose focus.
There was a great deal of speaker movement before the ARC was implemented. He asked my wife to sit in what looked to me to be a very near field listening position and yet it was at the apex of an equilateral triangle. My wife could immediately discern that the new position was much better. Specifically, instruments appeared and sounded a great deal more present and alive than our previous listening position. My wife had to leave to go to the library and when she left I shared that I knew, despite the clear improvement, that she was unhappy about the set up because the seating position was too close, so Mr. Lopez had to start all over again; moving the speakers further apart so the sofa could be further back and still achieve an equilateral triangle.
Mr. Lopez started the ARC process and I could clearly see on his laptop the response caused by the room. To say that the frequency response was not linear would be a tremendous understatement.
There are degrees of knowing; for years I have read that the room really impacts the sound; take care of room interactions first. The graph on his laptop hardly looked like the frequency response curve of the speakers shown by testing in an anechoic chamber. It is generally taken for granted that it is almost impossible to replicate outstanding results in the real world but the deviation in our living room was not to be believed.
When Mr. Lopez was done he asked us to choose a selection from the original ones we played and it was IMMEDIATELY discernible, immediately, as in less than two minutes just how improved was the sound; specifically the entire sound spectrum was balanced! We had not heard the presentation like that before so of course we could not know what we were missing. Choral voices to my ears were even more individuated and defined and yet the presentation became, for lack of a better descriptor, relaxed. It was ironic to me how we could be hearing more information with greater definition and at the same time the presentation was relaxed; not laid back in any way; just relaxed; there was also an effortlessness to the presentation.
Mr. Lopez’s experience (he has been with Martin Logan since 2002) cannot be underestimated; the software did not do the work; it was Mr. Lopez’s implementation, that achieved such an accomplished result.
In that sense what took place can be described as art, assisted by technology; Mr. Lopez’s artistry was evident as was his craft, and make no mistake it was craft too. The speakers were tilted a bit to the right and left, meaning from side to side respectively for each speaker and he worked tirelessly to make the lack of perpendicularity disappear. I am guessing most people would have been content to leave them as they were.
Mr. Lopez said “we are seeking perfection.”
I said “I am sorry you are working so hard” and he immediately and yet casually replied “it’s my passion!”
What more could I have asked for “it’s my passion” says it all; how many people do you meet that can claim the work they do is their passion?
Martin Logan is lucky to have him because he is insuring customer allegiance one at a time; the old fashioned way, via unparalleled dedication to results.
In the interest of clarity I want to emphasize that Martin Logan speakers are not finicky or difficult to set up; they are great from the get go, but with the extra attention comes extra-ordinary, extraordinary results.
Since Mr. Lopez cannot be cloned, owners would do well to inquire regarding his availability, since his primary responsibility is training dealership personnel.
Two months ago I upgraded from Vista to the Expression. For many months I was trying to convince myself that I'd be happy with Impressions, but within 5 seconds of hearing the Expression demo at the dealer I was hooked! The amazement continues, and continues . . . . These are better in every way! The sweet spot is larger and more forgiving at the boundaries, meaning the edges are a softer blending between sweet and not-as-sweet. The woofer integration is very good indeed! The ARC calibration works very well, simple to execute. I've very recently discovered that tweaking the bass stronger yields major dividends in dynamics, in addition to the expected fullness. This is a new experience for me with electrostatics as I'm used to having less impact from the panel in exchange for clarity, but now I don't feel that I'm lacking anything at all. I've currently positioned the panels about 40" from the front wall, less than where the Vistas were, and they sound brilliant! I will say that the Expressions definitely benefit from wider and taller absorption, partly because they are taller, but also because the sound field is wider. So on the front wall behind the Expressions I've got floor to ceiling absorption panels which are 30" wide and positioned in the first reflection area (between the speakers) more than a foot beyond (towards center) an actual mirrored reflection. Once I did this all rear-wave problems went away! The sound is gorgeous and I simply can't get enough! Sorry for all the exclamation marks, but they are well deserved!! Happy Customer!
