R 909 
 
偶较式音箱已经诞生很多年了，但较多的例子都是静电式的。这些设计的的音质一般都是非常好的，但较主要的问题就是这种类型音箱的低频段的重现总是不尽如人意——他们不能通过振膜产生自然深沉的低频。为了解决这个问题，音响总设计师Henrik Mortensen决定使用动圈式扬声器取代静电式……结果令人**。

“在这个过程中，我们面临很多挑战”，Henrik Mortensen承认：“这是一项艰巨的任务，在这个尺寸来制作雅致、美观的音箱。但是我想我们已经成功地开发了参考产品R 909……竟然丝毫没有妥协”！

随着尊宝参考级的R 909上市，我们提供给您体验音乐的机会，就如同在现场聆听一般。这款革命性的新型落地音箱使用了两只**的15英寸低音单元、一只镁金属中音单元（采用HCC技术，即硬锥盆技术）、以及一只特别定制的ScanSpeak（绅士宝） Revelator高音单元。所有的扬声器都安装在一块*特的、厚达43mm的多层障板上……这是能改变目前市场上高端音箱的面貌的产品。

R 909能与市场上较**的放大器**匹配。然而，由于它具有高达89dB的灵敏度和非常稳定的4欧姆负载阻抗，所以它并不需要用成员式的功放来推动……尽管在需要的时候它可以承受**过800W的峰值功率。采用这种设计和单元可重现清澈的人声和动态的响应，当您实际聆听这对音箱时，简直难以想象。异常坚实的低频，较佳的瞬态速度，贯穿在整个频率范围内**度和保真度（*没有音染和反射），让您置身于音乐之中。

也许很难相信，但一段很快的演示片断会让您有亲身体验——坐下来，好好聆听R 909，您将获得验证…

高音单元
如果想选择一个高音来重现**的高频，仅仅只有一个选择……那就是具有传奇色彩的绅士宝Revelator系列。然而，因为这个型号具有一个非常大的面板，和理想的状态相比，它将会被安装得离中音单元更远一些。所以，为了获得和中音单元天衣无缝的衔接，我们选择了搭配一个更小的合金面板。
 
这个高音具有1英寸软球**，多次上胶来获得*特的动态线性和谐振阻尼，所以能产生一个难以置信的圆滑、线性、动态和透明的声音。
 
驱动单元的Symmetric Drive Technology（均衡驱动技术）——一个在磁较芯上的铜环延伸过了音圈，弯曲进入球**腔——事实上消除了电相位漂移。并且，用它处理中频，也能很显着地减少失真。 
 
为了消除紊乱，磁路系统后面双阻尼优化腔体也配备了一个抗共振塞。而且在振膜后面特殊设计的腔，其周围的空气噪音和压力是较小的。事实上这个高音的制造很严谨，通过使用铁流体（磁液）衰减不需要的共振——这是通常的做法。
低音单元
由于大部分低音被安装在箱体上工作，作为偶较式结构的低音单元，和传统音响的单元是有显着区别的，我们不得不开发一个特殊的低音来满足这个开放式障板的需求。
 
这些**的低音单元具有高质量的镁金属盆架和轻质风干、带有橡皮折环的纸锥盆。用较其耗时的风干处理取代以前挤干水分的处理方式，即使是相同轻的材料，也能使纸盆更厚，从而更坚固。
虽然纸盆在在一些行业圈内不流行了，但它能够**地启动/停止，下潜非常深，他们使驱动单元更**、更有音乐味。
偶较
在房间里对箱式音箱（压力换能器）进行摆位是对自身的*特挑战。那么，偶较式音箱（或者说速度换能器）的又是如何“运转”呢？
由于偶较辐射模式，声音从音箱的前面和后面传播——相位相反。这对于一个传统的音箱是重要的，侧墙（也就是一次反射）反射和来自于驱动单元的**声是反相的，他们听起来会令人讨厌。 
 
然而，对于一个偶较辐射模式，实际上是没有“侧面”声音传播的，因此临界的一次反射声被*杜绝。
 
但是，您可能要问，音箱背后的声音传播是怎样的呢……不会破坏成像力和声场吗？ 
 
事实上，当被正确地放置，心理声学的规律开始起作用。人耳利用一次接收声（一次声波）来辨别声音的方向（也就是来源于哪里）。那也意味着即使反射声有一些延迟，也不影响头脑辨别方向。
 
如果偶较式音箱被放置在离后墙较小3英尺/1米的地方，微调角度（作为一个传统音箱的发烧友无论如何都会这样做），反射声将延迟(因为物理距离，实际上在到达聆听者耳朵之前，它将先通过两个边界——后面和侧面），但它仍然给我们方向的提示。这时候，二次反射将增加气氛，给聆听者一个更大房间的感觉。
分频
从驱动单元的描述上显而易见，我们想从**的驱动单元入手。正好，这样我们就仅仅需要来自分频器很小的帮助！ 
 
因此，尊宝R909的分频相当的简单——低阶分频结构。在R909里使用2阶分频的好处是无论从电学还是相位角都保持在一个非常小的值。这样，在音质方面和功放最后的负载来说，有时是非常重要的。在分频中使用**的Solen苏伦金属电容和空心线圈更能确保音质。
前障板
1.7英寸/43毫米厚的前障板由不少于7层的MDF板制成，在高压下胶制成形。圆弧外形提供给驱动单元适宜的工作环境，它可防止衍射并且更能增强硬度。
 
前障板本身配置了重60磅/26公斤的铸铁底座给分频网络和双线分音用的特大号接线柱。实心的双5x60mm不锈钢支柱配以特殊的断音装置，确保了前障板和底座之间的牢固连接。
中音单元
为了实现R 909的目标，我们也为中音单元使用了*的技术。这个Seas西雅士单元拥有一个**的钕磁铁排列结构，并采用镁金属振膜来提高刚性和确保轻质，这两个方面对动态的响应至关重要。得益于HCC（硬锥盆）技术，这个驱动单元在锥盆出现分割振动前到达9KHz。这使得贯穿整个频率范围的失真较低，而且中频非常开阔和富有细节，较适合人声重现。通过坚固的实心铜中心相位塞，可以对音圈散热。在高音量播放时，提供更强劲的功率处理能力和较重要的、较佳的声音稳定性。

 R 909
Absolute Sound Golden Ear Award ''''07 
Jan 2008

"This remarkable speaker, which uses dynamic drivers in an open baffle, offers the openness and resistance to room problems of a dipole planar combined with a power, solidity, and bass extension that few planers can even dream of. Coherent, dynamic, extended in the bass (to 27Hz), very low in distortion, and tonally well balanced, and the R 909 does a positively spectacular job of reproducing the scope and power of large-scale music."

LOUDSPEAKER OF THE YEAR OVER $ 2,500
Feb 2007

The revolutionary new Jamo R909 Reference Loudspeaker has just taken out two major awards, back to back. Hot on the heals of coveted European Title ‘Best High-End Loudspeaker‘, the R909 is back on stage again, this time receiving Australian ‘Loudspeaker of the Year over $ 2,500’.

EUROPEAN HIGH-END LOUDSPEAKER 2006-2007 
Aug 2006

With the sculptural R 909 speaker, Jamo’s development engineers have demonstrated what they are capable of delivering, when cost is no object, and only the best components and materials are good enough. The R 909 is among very few speakers that work without a box enclosure, which normally makes it difficult to reproduce low frequencies. So, a pair of high-efficiency 15-inch bass drivers and an ingenious crossover is Jamo’s response to this challenge, and since there is no ordinary box-generated resonances, the R 909’s sound is free of cabinet coloration, stunningly unrestrained, crisp and dynamic. This large speaker comes with an exemplary finish and superior attention to detail – an impressive “high-end” statement, which deserves the best amplifier that a demanding music lover can afford.

“What really frightened me after listening to these speakers is the thought that were it not for Henrik Mortensen''''s dedication and persistence, Jamo''''s R909s may never have seen light of day, which would have meant that the world would have missed out on a truly great loudspeaker, one that I predict will achieve immortality in the same way as Quad''''s original electrostatic.”

“The Jamos have glorious, full yet precise and extended bass, a bass undreamed of by any but truly enormous electrostatics. They are also free of the middle-bass “hole” that afflicts so many point source speakers. And as the symphony proceeded, the Jamos turned out to have a dynamic capacity beyond electrostatic realms. I was tempted to subtitle this review “the electrostatic perfected.” And while that might have been a bit mean-spirited it would not have been inappropriate, for the Jamos do have the same kind of low distortion, transparency, coherence, and smoothness ’stats have, but with a power and fullness that electrostatics can only dream of.”

“The Jamo is not just superb at reproducing large-scale music. With its cost-no-object midrange and tweeter it does superbly well with the small-scaled music, too. The Water Lily recording of Arturo Delmoni playing solo violin was right on the mark as to tone, while the reverberant acoustics of the church where the recording was made were revealed naturally, with clarity but no exaggeration.”

"And the Jamos are very room-friendly: we had our largest room earmarked for them, but we were encouraged to try them in a smaller space, where they worked just fine on the end of our Naim/Krell reference system. Whatever you’ve heard about the problems of room interaction with dipole speakers like these, the R 909s just get on with the job, provided they have a metre or so of space behind them and a gentle toe-in toward the listening position.
While these speakers can indubitably do ‘big’, with a rich, powerful and well-defined bass, their main characteristics is subtlety, whether with the finer details of voices or the way in which they reveal the recorded acoustic."

"They slam, they deliver the rush of a full orchestra, they let you hear each breath a singer takes and, above all, they’re special." 

"Verdict: The new Jamos are as accomplished as they are daring, with a sound that more than lives up to their price: lovely!"

HI-FI CHOICE, UK

“In short, this is a speaker with personality. What you get here is an enormous sense of scale, far exceeding conventional speakers, even big ones like B&W′s larger 800 Series models. And yet somehow Jamo has conspired to deliver this scale without any obvious sins of overhang or “boom”. The sense of drama, of the physical presence of musical performers right there in the listening room, appears to be intrinsic, where more conventional speakers with a similar balance often sound overblown.”

“From one point of view, the big easy and relaxed sound of this speaker is one of its greatest strengths, especially as it is achieved without loss of detail, and without sounding “blowsy” or out of control. And this is exactly what the R 909 does achieve. Sure, it is perceptibly warm, but the bass is unusually tuneful and well proportioned in its own right. Orchestral entries are well timed, with the kind of balance and weight you might well be looking for when seated, say, one third to one half of the way to the back of many concert halls; the kind of balance that allows a rich, yet complex sound from the cellos and double basses.”

“Conclusion
An individual take on the high-end loudspeaker, the R 909 is relatively easy to integrate into real world systems and rooms, and its proportions look just right (not a given at this end of the market), the shallow depth being especially striking.”

Editor’s choice
Overall score: 89%.

“Key sonic features of R909 include a very spacious (almost natural-sized) soundstage, and a fantastically deep and powerful bass – which at the same time sounds absolutely true to life. Beyond any doubt, such an impeccable performance is an extremely rare treat even in the world of top-quality audio”.

“The new Danish speakers scale up a musical event without distorting the delicately balanced proportions between the sound image elements. They create a vast soundstage with natural ambience and softly outlined borders, and enhance listeners’ emotional perception of music to a great extent. R909’s reproduction of symphonic and organ music is amazingly close to the original performance in a real concert hall or a gothic cathedral.” 

“The new Jamo speakers reveal the full potential of classical stereo reproduction. Their sound reproduction opportunities are really impressive and spacious. R909 is able to draw listeners’ attention to little-known music, and to cast fresh light on familiar records endowing them with surprising new quality.“

“These speakers sound almost like no other speakers we have encountered. 
Their effortless and natural way of playing possesses such an obvious authority that almost everything else sounds boxed-in, smeared out and slow. “

“With Jamo you are again reminded how absolutely spellbinding "trivial" stereo listening actually can be.”

“The bass is firm and majestic in a way that now and then almost cancels the law of gravitation.”

“Despite its natural and realistic way of playing, it is perhaps the unmovable and firm musical grip through the entire frequency range that is the most distinct Jamo characteristic, the ever sought for feeling of actually being there, to put it simply.”

“The R 909 might usefully be combined with a very high-end cabinet bass-speaker (subwoofer). However, the most impressive aspect of the performance of these speakers is their incredible impact. We are miles away from the sensations delivered by even the best cabinet bass-speakers of conventional design. There is no perceptible ghosting, and the speakers delivers a clean, crisp and spirited clarity of attack. Likewise, there is not the slightest coloration of the sound output. Transparency and naturalness of restitution of this quality are rarely achieved. The tonal balance is perfect, and the total absence of ghosting lends a striking relief to the sound.”

“In conclusion
With the R 909, Jamo have tackled the challenge of the open baffle, much beloved of audiophiles. By considering each of the problems raised by this technology and delivering appropriate solutions based upon new design concepts, this manufacturer has produced a remarkable speaker with and impressive performance, providing and unforgettable experience for the listener whose primary concern is to enjoy an unconstrained sound space, with impressive levels of realism. Some ungenerous souls might find fault with the lack of weight in the extreme bass register, but is it really natural to hear a double bass snorting like a compressor on a building site?”

“Treble (which I didn''''t expect problems with) is very correct, not aggressive nor too soft. The ScanSpeak unit used provides a very clean standard of reproduction. Same with midrange, which is in perfect harmony with the treble but with the necessary strength to give body to even to the most difficult instruments. The bass is of, quite honestly, spectacular quality. I really didn''''t think that a “cabinet” like this Jamo design could generate such a result. I''''m stunned.”

“Conclusion:
The Jamo''''s R 909 are much more than a letter of intent. Their design removes several barriers to good listening and renews our faith in a loudspeaker concept that we always admired. There are no real caveats here and I can''''t imagine the R 909s failing to satisfy…. I fervently recommend listening to them. And if you do not feel satisfied, think instead about different partnering equipment, perhaps a bigger power amplifier or a larger listening rooms. One thing''''s for sure… it won''''t be the Jamo R 909s that are at fault…”

“Verdict: 6 of 5 stars!”
