哪位朋友听过这对丹麦喇叭？ [复制链接]

以前我听过，但用安桥AV功放推的，控制不好，让我印象最深的就是吸铁石网罩和用18颗螺丝固定的后障板。

高音看上去像西雅士的单元，箱体内部好像还有单元。

有玩过的朋友吗？我相信这对喇叭应该是丹麦原装的东东。

jamo里声音非常棒的型号。难推是硬伤。推好了，就可以安心听音乐。安桥估计没戏。得找巧力的对付。

听朋友说，在日本人家用金嗓子推。这个系列的喇叭好像当时不贵的。能介绍一下他的声音特质吗？我想肯定跟我们以往对尊宝的理解是不同的。

这个喇叭让我想起KEF的Reference系列

低音的工作方式和KEF的有很大的差别。估计金嗓子的廉价机都不行。找KRELL和NAD试试。

您能具体介绍一下吗？他肚子里有几个低音单元？什么声音风格呢？还有Jamo的旗舰Orel素质如何？谢谢！

具体的细节遗忘了，毕竟是十几年前的事了。当时觉得效率不高，声音相当内敛，低频受扩大器的影响比较明显，用推力一般的就软弱无力。

是的，有年头的东西了，当时我看了这箱子的后障板就知道这不是一般的喇叭。

「音響論壇」的老讀者可能會記得劉總編曾經在22期（哇！真是很久以前了。造型精美聲音超值的Jamo Concert VII喇叭）介紹過另一對Jamo的喇叭Concert VII，其中提到那對喇叭的低音單體裝在喇叭的下半截音箱中，而且是兩個一對。707i也採用了類似的設計，不過細部設計上還是有不相同之處。當時Concert VII的低音兩只都是反射式設計，而兩個反射孔則以同心圓排列，707i的低音則是一只為封閉式設計，另一只為低音反射式設計

The Concert VII model incorporates a Band Pass Reflex System. One of the two bass drivers is housed in a small bass reflex enclosure tuned to 150 Hz, and the other in a larger enclosure tuned to 30 Hz. With careful calculation of the correct cabinet volume, and the tunings of the two bass reflex ports, Jamo achieved a remarkably smooth and consistent bass performance.
The diagram of the enclosure clearly shows the ingenuity of the system. At the top of the cabinet is a midrange driver in its own sealed compartment. This is a 167 mm polypropylene driver with a soft rubber roll surround, mounted in a slight recess on the NCC front baffle. This covers the frequency range from 150 Hz to 3.5 kHz. Below it sits the same tweeter used in the Concert V, again with a hole drilled in the magnet pole-piece, and mounted in its own carefully damped enclosure. This combines with the recess in the front baffle to achieve perfect phase response at the typical listening position.
The two bass drivers can be seen inside the cabinet, mounted face-to-face, and in their own compartments. What appears initially as a large port below the tweeter turns out to be two ports, combining to move the bass response down to about 30 Hz.
The crossover required to sort out the signal stream was designed as a ‘dual slope’ network. It incorporates heavy duty air-cored and iron-cored inductors and polyester capacitors, mounted onto a solid PC board. This is directly soldered to four 24-carat, gold-plated, 4 mm binding posts, which make bi-wiring and bi amping possible. A protection circuit for the tweeter has also been included.
The small details that differentiate great speakers from good ones have not been overlooked. The grille frame, instead of being made with the typical wood or plastic of most speakers, is made of 1 mm thick steel plate, which is attracted to the edges of the baffle by small magnets. This simple, but very effective technique, eliminates diffraction, as well as being more durable than the usual plastic lugs.
The edges of the bass reflex ports have been chamfered to avoid air turbulence in the ports. Inbuilt adjustable spikes are standard fixtures on the speakers’ feet. The finish is genuine timber veneer and is available in either mahogany, black stained oak, or white.
The Concert VII is doing exactly what Jamo had hoped. It has put them right back in the fray, and the Jamo name is once more associated with audiophile loudspeakers; but audiophile loudspeakers that deliver exemplary performance at a reasonable price. Small wander the Concert loudspeaker series has been such a resounding success. (Source: Stereo Buyers Guide, 1991, pages 80-81.)
