DIY Speaker Choice

你可以起个主题啊。
昨天听了，想想这是需要那么大的房间才可行的。下面是个借用照片(from http://www.canuckaudiomart.com/forum/viewtopic.php?f=4&t=3591)，前面看起来是基本一样的（这个才8", 听的是12”的.

起个主题， 这个是老的设计，新的已经用两个高音。低音应该和前天我们听的一样， 10“ Peerless Subwoofer

Orion 的新设计，全是sears的单元

Positive.

Dynamic, clean, fast, articular bass, tonal balance is good.everything is one or two notch up from my current setup.

The only thing is I felt his room is too large, not easy to fill up the whole space(around 6 times my place and high ceiling, but the speaker mange to do pretty good( I a bit hesitate to turn the volume too high)

Using his Emotiva $250 DAC and under $1000 amp, I have heard the best piano cd recording so far, the the size of piano is quite right.

I expected more from the detail, seperation and closer presentaion, but I think the limited factor is his room size and the source.

At this kind of money (around $5000 - $6000), I see lots of potential and it should perform even better in smaller room.

Haha, 我喜欢"魔芋", 多谢.

我感觉房间太大，反射被衰减的太多，像巴赫的管风琴，高音很清楚，但显得太遥远，没有空气感（混响）?

Orion对房间大小有要求的，不能太小，也不能太大。

。。。

开工的问题，这个是任重道远，准备一两年的时间把

[silent_fish]

声短路? 请解释一二.

高音单元是封闭的,应该没有影响吧

[silent_fish]

又错了(为什么我说"又"呢?)

Dipole 音箱需要反射来营造深度,怎么会需要无限大小的房间呢？完全不对，发回重写


这箱公认定位一流，属于数人头那种，看看这位前HP principal engineer的设计理念

The challenge
to build a state-of-the-art loudspeaker yourself
+++ Build this unique loudspeaker yourself or let us build it for you +++

My experience with the Beethoven series, the Vivaldi, and PHOENIX, has led to a new design, which captures the essential sonic features of those speakers, except in a smaller package, one that would be more acceptable in many domestic situations. I named the loudspeaker





It should be understood that engineering is about trade-offs. In this case I have given up some maximum volume capability below 40 Hz, that may be required for a few music recordings when played at very high levels, while maintaining an extended frequency range down to 20 Hz and gradual 2nd order roll-off below it. In return I have a speaker with seamless integration over the whole frequency range, with impactfull dynamics, a speaker that sets up a wide, tall and deep sound stage, yet with pin point localization of instruments and voices, with speed and warmth. All this, of course, only for well recorded material. The speakers disappear and what remains is the panorama of sound and the experience of music. I am very pleased with the accuracy and balance of sonic attributes that this speaker achieves. Combined with its relatively small size and its looks it represents to me an ultimate speaker, one that I could live with for a long time, because it provides such a satisfying musical illusion and experience.

The ORION design manifests to me what Saint-Exupéry mused about when he described his airplane in "Night Flight" and wrote something like: "A machine is not perfect when you cannot add anything more to it, but when you cannot remove anything without destroying its function." Thus the appearance of the ORION also exemplifies the Bauhaus motto: "Form follows function

[silent_fish]

多谢好意。

这个喇叭设计是几乎免费公开的，不是商业行为，他的“公认”一定比其他的商业品牌的“公认”好。

所谓声短路就是衍射，波长越大，影响越大，中音有障板，高音全封闭，主要不是声短路的问题。

只要有倒相口，就需要摆位，这个和Dipole OB一样的。

Orion 还提供测试cd测频率相应，这个是science 和 engineering ， 不是瞎白虎

　　声短路是指扬声器的振膜向前或向后运动时声波是反相的，导至声波互相抵消，所以声音也很轻。 　　形象的理解就是：喇叭工作的时候靠音圈带动纸盆的震动来推动空气，空气的震动传到耳朵就是声音。当某一瞬间纸盆往前运动，则喇叭前方的空气密度大，后方的空气密度小，如果没有什么阻拦，前方的空气会绕到喇叭后方去“填空补缺”，就象站在水中央浇水一样，花再大的力气也很难让前面的水多起来。喇叭的这种情况称之为“声短路”，象象站在水中央浇水一样，许多“功”都白做了。声短路与频率有关，频率越低越明显。

魔芋, 你听的这地方是个商家？还是私人卖家？

只是在DIY用家试听而已，大部分Orion都是自己做的，有一个小小的用户社区，可以联系试听，交流经验。

设计者Siegfried Linkwitz的伙伴也开始提供商业版本，不过Siegfried始终坚持有相应的DIY版本

那我们去听现场交响乐全都短路了！得建个箱子把乐队藏起来啊！

haha，我想声短路主要是效率问题。

[silent_fish]

大学里做了个10寸还是12寸的，两个抽屉做音箱，声音够大声，也还不错。

[silent_fish]

Eh, 先衍射再干涉，跟声音的轴向特性也有关系吧。

声压减少，效率不就低了吗

[silent_fish]

老广不愧是专业人士

这对箱专长于classical和jazz(vocal的表现有待证实),有靠后的声场,未必适合所有人

哈，还是怪你，开头一句就是“狗了一下”，接着一大通都被我当成狗出来的了。
好奇心被吊起来了，得自己听听，光听你们吹牛不过瘾。

Burlington还有一家可以提供试听,我可以把联系电邮给你

[silent_fish]

Nothing is perfect, the speker design has to be compromised. I am not into "box" sound either.

You have to listen first to qualify for a review.

Compared with commercial speakers, you got what you paid for Orion.

[silent_fish]

说实话,听钢琴没有,感觉grand piano就在两个喇叭中间.

只是在听管风琴高频的时候,不过事实上我在教堂里听到的确实是飘渺的不过是可触摸的. 还有张Ella的老碟也是,人声靠后

也可能是录音,音量的问题,影响的因数太多.

联系电邮已经发给你

[silent_fish]

可是使用引用的论文得出个"Junk"的结论,这也太主观和大跌眼镜把,

[silent_fish]

Come on, 如果你只是要比较sub woofer,早点跟我说阿

Orion 有配套的sub woofer Thor

http://www.linkwitzlab.com/thor_construction.htm

[silent_fish]

后者的机会非常小

[silent_fish]

握爪

[silent_fish]

看起来巨型，是什么板，准备采用什么设计？

[silent_fish]

Orion-4是商业版，和DIY的3.5是一样的。

低音单元和方向给改了
