全频带音箱伴随着玩古董机的热潮而逐渐流行起来。在资深的玩家中,通常是搜寻名贵的古董全频带单元,装配成号角负载式、无限障板式等形式的音箱,然后配上小功率的单端A类胆机,立刻就获得迷人的播放效果。这类系统中的主角全频带音箱,由于是由一只单元负责整个工作频段的插放,所以可以避免分频器所带来的功率损耗、相位失真等问题,也解决了多只单元必须协同工作的问题,因而在音质、搭配、播放效果等方面具有先天上的优势。不过,俗话说“针无两头利”,由于全频带单元是必须同时负责高、低频段的重播,而且频响曲线还必须力求平坦、宽广,但实际上高频的播放和低频的播放,对单元的要求是不同的:对高频的重播要求单元的振膜必须轻而薄,面积要小才行,这样才有利于获得良好的瞬态和延伸;而为了获得良好的低频,振膜则必须有一定质量和面积。显然,这两者的要求是矛盾的,所以才会有专门的高音单元和低音单元出现。而全频带单元恰恰就要同时完成这两样矛盾的工作,再加上要使频响尽量宽阔、平坦,你想这要求有多高?!所以,优质的全频带单元制造难度相当高,而且很多型号已经停产,可选的范围本来就很窄,造成单元价格高昂。像Diatone,WE、Altec、Fostex、Goundmans、Axiom等品牌的经典型号更是可遇不可求。从而使全频带音箱一直成为小部分既有经济实力、又有眼光的资深玩家的专属品。不过,随着Supravox这个新品牌的进入。这种现象或许有一定程度的改善,因为Supravox的定位就是以相对低廉的价格,让更多发烧友可以领略到全频带音箱独特的魅力,像今天这款BS-5书架箱的售价也不过是5700元。 Full-band speakers along with the craze to play antique machines and gradually become popular. In the senior players, usually search for expensive antique full-band unit, assembled into a horn load, infinite baffle and other forms of speakers, and then coupled with low-power single-ended Class A amplifier, immediately get a charming play . In this type of system, the lead full-band speaker can solve the problems of power loss and phase distortion caused by the frequency divider and also solve the problems that multiple units must be coordinated because one unit is responsible for inserting and dropping the entire working frequency band Work, so in sound quality, collocation, playback and other aspects of the inherent advantages. However, as the saying goes, “a needle has no advantages”. Since the full-band unit must be responsible for both high and low frequency replay, and the frequency response curve must also strive to be flat and broad, but actually high-frequency playback and low-frequency playback, Unit requirements are different: the replay of high-frequency requirements of the diaphragm diaphragm must be thin and light, small area Caixing Caixing, so as to achieve good transient and extension; and in order to obtain a good low-frequency, diaphragm is Must have a certain quality and size. Obviously, the requirements of both are contradictory, so there will be special tweeters and woofers. And the full-band unit just accomplishes both of these contradictory work at the same time, plus how high and flat you want the frequency response to be as high as possible ?! So high-quality full-band units are extremely difficult to manufacture, and many Models have been discontinued, the optional range has always been very narrow, resulting in high unit prices. Like Diatone, WE, Altec, Fostex, Goundmans, Axiom brands such as the classic model is a rare event. So that full-band speakers has become a small part of the existing economic strength, but also vision of the exclusive players senior players. However, with the new Supravox brand entering. This phenomenon may be a certain degree of improvement, because Supravox positioning is relatively low price, so that more enthusiasts can enjoy the unique charm of full-band speakers, as today’s price of this BS-5 bookshelf is nothing more than 5700 yuan.
