双线分音，低频电流和中高频电流分别走不同的路径，不会互相干扰，理论上说应该有更好的效果，更好的声音分离度。但是两对喇叭线应该是同一规格（型号和长度），这样才能保证高低频电流同步。请有玩过的双线分音的烧友谈谈实际听感是否如此。谢谢

在用，确实如此。

刚在看一本书，中间有提到Bi-wire，先贴上来，不知道对你有无用了。文中确实有提到用不同的2组线，适合低音的接低音，适合高音的接高音。慢慢看。

Bi-Wired Loudspeaker Cables
Bi-wiring is running two lengths of cable between the power amplifier and loudspeaker.
This technique usually produces much better sound quality than conventional singlewiring.
Most high-end loudspeakers have two pairs of binding posts for bi-wiring, with one
pair connected to the crossover’s tweeter circuit and the other pair connected to the woofer
circuit. The jumpers connecting the two pairs of binding posts fitted at the factory must be
removed for bi-wiring.
In a bi-wired system, the power amplifier “sees” a higher impedance on the tweeter
cable at low frequencies, and a lower impedance at high frequencies. The opposite is true in
the woofer-half of the bi-wired pair. This causes the signal to be split up, with high frequencies
traveling mostly in the pair driving the loudspeaker’s tweeter circuit and low frequencies
conducted by the pair connected to the loudspeaker’s woofer circuit. This frequency
splitting reportedly reduces magnetic interactions in the cable, resulting in better sound. The
large magnetic fields set up around the conductors by low-frequency energy can’t affect the
transfer of treble energy. No one knows exactly how or why bi-wiring works, but on nearly
all loudspeakers with bi-wiring provision, it makes a big improvement in the sound.
Whatever your cable budget, you should bi-wire if your loudspeaker has bi-wired inputs,
even if it means buying two runs of less expensive cables.
You can bi-wire your loudspeakers with two identical single-wire runs, or with a
specially prepared bi-wire set. A bi-wire set has one pair (positive and negative) of terminations
at the amplifier end of the cable, and two pairs at the loudspeaker end of the cable.
This makes it easier to hook up, and probably offers slightly better sound quality.
Loudspeakers can also be connected with a single bi-wire set in which a single cable
with multiple internal conductors has two pairs of terminations on one end and a single
pair of terminations at the other end. Although this approach is much less expensive than
two runs of cable, you lose the benefit of magnetically isolating the low- and high-frequency
conductors from each other. Two bi-wiring options are shown in Fig.11-2.
Most bi-wired sets use identical cables for the high- and low-frequency legs. Mixing
cables, however, can have several advantages. By using a cable with good bass on the lowfrequency
pair, and a more expensive but sweeter-sounding cable on the high-frequency
pair, you can get better performance for a lower cost. Use a less expensive cable on the bass
and put more money into the high-frequency cable. If you’ve already got two pairs of cable
the same length, the higher-quality cable usually sounds better on the high-frequency side of
the bi-wired pair. If you use different cables for bi-wiring, they should be made by the same
manufacturer and have similar physical construction. If the cables in a bi-wired set have different
capacitances or inductances, those capacitances and inductances change the loudspeaker’s
crossover characteristics.

小生也有类似的问题,如果是电子分音的喇叭要用几台后级驱动的话,是不是后级到喇叭的喇叭线要同一型号,相同长度?电子分频器到后级的信号线是不是也是要相同规格的??

1、两对线和一对比是不是一定有提升？主要表现在哪些方面？
2、两对线的成本也上去了，是否用两对的钱买一对更高档次的线提升更大？
请有这方面建议烧友不灵赐教。

分频以前功放输出的都是一样的，只是不同的线会对声音有不同的影响，分频后才谈得上中音和低音分别传输。如果没有现成的成功经验，两对不同的线玩双线分音成功率极低，用两条相同的更没意义，同样的代价完全可以让线材升一到两级了。

双线分音，提高声音分析力，对低频的控制力更好。建议使用相同的喇叭线

除非你的功放有两组或多组输出，如果单从一组输出接两对线或多对线，毫无意义。

还是有效果，双线分音，降低了喇叭线的阻抗，提高了阻尼系数，控制力好，声音宽松些

我十多年来一直用的是Ｂ&W Ｍ8系列音箱（无论是B&W M804、Ｍ803Ｓ2还是Ｍ801Ｓ3），厂家均强推荐用双线分音或双功放，我一直用的是双线分音版的喇叭线，如ＡＱ sterling SE 的双线分音版，ＡＱ火山岩的双线分音版，这些线里边，走高音和走低音通道的线材质是完全不同的，走低音的那一组如果接到高音上，那基本上是没啥高音的，我以前就曾用ＡＱ 火山走低音的线接到没有双线分音的ＡＴＣ 20上，造成ATC 20发挥完全失常。
个人建议直接用线材厂家已 分好的双线分音版喇叭线，声音会比较协调，并充分发挥高音、低音组线材质的优点。

经销线材之后，手头的线比较多，对双线玩法试过很多种方案。
双线分音，多数时候两端延伸和解析会提升，但音乐味有时会降低。
原厂双线分音版的喇叭线效果比较保证，同型号的单线接两对，总体是全面提升，但幅度不算大。不同材质、不同长度的喇叭线玩双线，多数时候是失败的。声音脱节，不耐听。
相对来说，还是单线+跳线，性价比更高。

多谢各位分享经验，看来可能还是用单线性价比更高（同样价钱可以升级更高档次的喇叭线）。另外还有个问题，跳线对声音的影响会很显著吗？是否只影响中高频？
