子弹头果然好玩——Eclipse TD508MK3 全频小喇叭

交易区新帖推荐

我玩过、自用过、推荐过一款日本Eclipse的子弹头桌面有源喇叭TD-M1。那是我近年来接触过的桌面无线有源喇叭里除了帝瓦雷Phantom之外最好玩的一个。
当时写的介绍文字： http://blog.sina.com.cn/s/blog_4e2a04300102w99b.html

Eclipse这个牌子大家都不熟悉，我之前也不知道，但提起富士通Fujitsu，很多人一定熟悉它的笔记本电脑，我自己也用过。其实Eclipse就是富士通公司的音响产品牌子。其独特的子弹头形状喇叭设计，带来了很好的声音，其用到的全频喇叭单元好像也是自行设计的。

这两天，我又开始把玩Eclipse的一款无源子弹头小喇叭——TD508MK3。虽然它不像TD-M1喇叭那样内置了解码和放大器，需要像传统书架箱一样给它搭配音源和功放，但短暂的煲机后，我马上注意到，这也是一对非常好玩、声音特色十足的小喇叭。值得为它专门写一写。

TD508MK3小喇叭和TD-M1一样，也采用了一个厂家研发的8厘米直径全频单元。但是TD508MK的子弹头腔体比TD-M1要更大一些，也就是喇叭箱体更大一些。不过508仍是体型不大的小喇叭，适合小房间使用。煲喇叭时为了方便为把它直接接入大系统去听，结果在我20多平方米的听音室里，显得很小了，低频能量也不够，但经过几十个小时的初步煲机后，即便是在超过它适合范围的空间里，居然声音也完全能欣赏！只是不适合开到太大的音压。在这方面，Hi-Fi小喇叭几乎都不能和Phantom相比。

必须科普一下，喇叭做成这种鸡蛋形状、恐龙蛋形状、子弹头形状、圆球形状，等等，都不是为了好看或故意追求设计感，而主要是为了取得更佳的声学效果。虽然大多数喇叭都是立方体，但从理论上说，四四方方的箱体是声学特性最差的，最容易产生和受到各类驻波、谐振的影响和干扰，也就是一般所说的“箱声”。声学特性最佳、最不易产生箱声的，就是类似圆球形的箱体。小喇叭里，帝瓦雷Phantom、Eclipse的子弹头喇叭，都是此类追求声学特性优化的作品。

当然，类似圆球体的喇叭，加工制作难度最大，箱体的制作成本会远高于四方体。由于木材是无法加工成圆球箱体的，所以此类形状的喇叭箱体多半以树脂和聚合物等材料制成。

这是一段秒拍视频，有兴趣的可以看看。这个TD508MK3喇叭下面是底座，其实适合摆放在桌子上，但我还是考究地把它放置在一对TIGLON的镁合金脚架上，下面还用了钉垫。在试玩这对喇叭的过程中我发觉它对脚架竟然是反映很灵敏的，如果直接摆放在普通桌面上，声音会不如优质脚架。如果一定要放桌面的话，强烈推荐下面用音响避震板。这点上它和帝瓦雷Phantom喇叭是一致的——随便桌子上一摆根本听不到它的全部能力，必须注重避震处理。经常有人抱怨Phantom喇叭高频不好，其实下面用优质脚架承起，就知道它的高频特性完全可以很不错！直接落在桌子上都闷掉了。

煲喇叭过程用了德国Audionet放大器，比较奢侈，如果实际使用的话，无此必要。这对喇叭的额定功率15瓦，最大功率30瓦，用小功率的放大器就可以了。

看到tmb50垫喇叭了，这个板子我也是觉得垫喇叭真的很好。

嗯，喇叭下面垫避震板挪动起来也更方便。板子直接在地上推。

关键是声音很好，和aba厚板大理石等都试了，tmb50更适合喇叭

td-m1的用家支持一下，最近听eclipse比voxativ更多。
eclipse喇叭有种玩法是多声道，据说达成的声场别具一格，非常出色，占地也小。另外还曾经看到杂志上介绍有的冥想，按摩店也喜欢用eclipse，估计是因为声音和外型店清，暗，澄有关系吧～

有网罩可以罩起来。那时就总有一副带着眼镜的眼睛看着你，哈哈。

音响脚钉直接放在类似高丘、音神之类的厚避震板上，跳过盯垫，不考虑具体声音表现，从放置上来看，应该也行吧。

不理想的。尖钉的下面用专用钉垫更理想。而且不同的钉垫，声音明显会不同。

富士通TD系列子弹头喇叭的全频单元都是自行设计和制作的，采用了玻璃纤维材质的振膜，分为8厘米单元、10厘米单元、12厘米单元等几款。不过要注意的是Eclipse家的全频单元并非高灵敏度单元，不像很多全频单元那样有着接近100分贝的灵敏度。比如TD508MK3喇叭的灵敏度只有82分贝／毫瓦，显然是偏低的灵敏度。所以驱动方面它不像那些高灵敏度全频喇叭只要几瓦的单端胆机就可以对付，而是需要大一些的功率。

我在慕尼黑的Eclipse展房里听过其TD系列目前最高端的TD712Z喇叭（12厘米单元），表现非常出色，可以说是高度细致和透明的声音。说实在的，我心里确实考虑过入一对TD712Z喇叭自用呢。

如何评价TD508MK3小喇叭的声音呢？主观上随着进一步的试听我越来越喜欢这对小喇叭了，这样，先让我搬来英国What Hi-Fi?杂志对这个喇叭的评论，懂英文的自己看。看不懂没关系，我在下面简单翻译和说明。

Eclipse TD508Mk3 review: design

There’s real substance to the design. While it’s true that a single drive unit – even one as highly developed as the 8cm fibre-glass one used in the TD508Mk3 – can’t cover as wide a frequency range as multiple driver alternatives, there are many plus-points to consider.

One driver reproducing all the sound means there are no integration issues, and no need for a crossover circuit that invariably introduces all kinds of distortions while sapping detail.

Eclipse is obsessed with how its designs respond to an impulse function – a high-level signal that only lasts for an instant. In theory, if a speaker gets this aspect right, every other sonic parameter will follow.

Eclipse TD508Mk3

The Eclipse TD508Mk3’s cabinet is equally unusual. It’s egg-shaped for rigidity and to avoid any reflective edges, which can spoil the stereo imaging.

The speaker is cleverly engineered so that any vibrations caused by the driver are first fed into a high-mass anchor and then dissipated down into the stand. The enclosure is supported by the anchor, but decoupled from it to reduce any mechanical energy transfer. This way cabinet vibration is minimal, and so it contributes far less to the overall sound than would usually be the case.

The TD508Mk3 speakers are intended to be as flexible as possible. That pedestal stand is adjustable over a wide range of angles and these speakers can be wall or ceiling mounted, as well as fitting in well in the usual places such as on a stand or shelf.

Eclipse TD508Mk3 review: performance

How do the TD508Mk3s sound? Given their distinctive engineering it would be a shame if they sounded ordinary. They don’t.

We’re astounded by their speed of response, and the level of insight they offer. Low-level subtleties in dense recording such as Orff’s Carmina Burana are readily revealed, and can be followed easily as the music gets more demanding.

The Eclipse speakers’ presentation is impressively composed when stressed by complex material, keeping the all the music’s instrumental strands in place and proportion.

More after the break

Eclipse TD508Mk3

Set up, with care taken over toe-in angle, these speakers deliver a wonderfully laid-out soundstage: it’s solid and intricately layered with suitably well-recorded material. Even the best of their conventional rivals, such as the ATC SCM 11 and KEF LS50 speakers, sound vague and imprecise in comparison.

The Eclipse’s rhythmic ability is terrific, too. It catches the leading and trailing edges of notes superbly, and maintains the timing relationships between sounds immaculately. The changes of pace and rhythmic drive of Dr John’s Revolution are conveyed brilliantly.

These speakers fall short in all the areas where such a small design with just a single 8cm drive unit would be expected to struggle. Bass depth is limited and this affects the Eclipse TD508Mk3’s ability to deliver authority and dynamic punch.

Given a demanding, bass-driven piece of music such as Time from the Inception OST, these Eclipses just sound small and undernourished. There’s no denying the insight, even at lower frequencies, but equally the sense of power in this recording isn’t communicated well.

There’s less of an issue with treble in this speaker than we’ve had with its larger relatives. Higher frequencies sound relatively open, but still lack some of the texture and sparkle that good dedicated tweeters have.

While Eclipse has made good progress in all these areas compared with earlier version of the 508 – a slightly larger cabinet, revised drive unit and anchor assembly all help – it’s still found wanting next to conventional alternatives.

Eclipse TD508Mk3

In its areas of strength, though, we have no doubt that the Eclipse TD508Mk3 is as good as it gets at this price – and well beyond. In fact, to match or better the TD508Mk3’s strengths you have to buy its big brother, the TD510Mk2, and that costs around ￡2000.

Eclipse TD508Mk3 review: verdict

We normally award five stars to excellent all-rounders, but in this case, as we have done with other Eclipse speakers, we’re willing to bend our rules a little.

So good are the Eclipse TD508Mk3 speakers in specific areas that they make even the very best of the competition sound inept. If you like what these Eclipses do, nothing else at this price comes close.
