Raymond Cooke 于 1961 年创办了 KEF,他与 BBC 有着密切的联系,20 世纪 50 年代初,他曾在 BBC 工程设计部门工作,与 Dudley Harwood 和 D.E.L.Shorter 等著名音频工程师共事。60 年代初,Cooke与BBC重新建立了合作关系:双方签订了一项协议,协议许可KEF生产 BBC 设计的 LS5/1A 监控扬声器,该款产品的生产一直持续到 70 年代中期。同期生产的产品还包括 LS5/2、LS3/4 和 3-路 LS5/5,KEF 还为 3-路 LS5/5 扬声器系统制造了 12 英寸和 8 英寸中音单元。KEF 精益求精的生产方式非常适合制造这类要求高度精确的监控扬声器。

 

KEF 与 BBC 研发部门最初在 Kingwood Warren 进行的沟通多集中于扬声器振动膜和边缘新材料方面。KEF 用聚苯乙烯和铝箔层板制造 B1814 和 B139 的低音单元,用聚酯薄膜制造 T15 高音单元的振动膜。20 世纪 60 年代中期,BBC 开始尝试使用塑料,结果制造出了采用 Bextrene 锥盆的三路 LS5/5 扬声器。

1967 年,KEF 推出了 T27 (A6340) (一种 19 毫米的球顶高音单元,采用聚酯薄膜振动膜) 和 B110 (A6362)(一种 110 毫米的低音/中音单元,这是第一款上市销售的 Bextrene 锥盆驱动单元)。这两种驱动单元推出后立即被应用到同年发布的 Cresta 书架式扬声器系统当中,后来还用于 1969 年推出的三路 Concerto 系统。根据当时的惯例,公司向 BBC 展示了这些驱动单元,并随后将小批产品送交评估。

1968 年,BBC 决定研究声学模拟技术,以便辅助新音乐演播室的设计 [1]。为此,他们需要一种最高能产生 100kHz受控声辐射的小声源。为实现这一目标,BBC 首先生产出了一种两路系统。

低音部分最高工作频宽需达到15kHz,包括由 BBC 制造的两个 110 毫米 Bextrene 锥盆驱动单元,互呈 60 度角安装,以达到理想的宽广弥散效果。为了达到 15kHz 的频宽要求 (注意,KEF B110 支持的最高频宽仅为 5kHz 左右),锥盆采用深度扩张设计。同时,为了降低锥盆颈部的声模效应,就在正常防尘帽附近加装了一个 PVC 振动膜。15kHz 以上的频率范围则由呈半球状排列的静电传感器同轴共点单元再现。

但后来发现,这种系统性能欠佳,因而对其进行了改进,由此衍生出了3 路系统[2]。这种系统中只有一个 110 毫米低音单元朝前放置,与一个 3kHz 的 KEF T27 高音单元相交,该高音单元工作频宽最高可达 15kHz,超过此范围时则分频至高频同轴共点单元处理。

改进系统的性能得到了显著提高,在播放普通节目素材时音质十分出色,这表明该系统可用以制造小型监控扬声器,适于在室外广播演播室等空间十分有限的场所应用。因此,开发人员利用原来的 KEF B110 (A6362)、 KEF T27 (A6340) 和分频滤波器 FL6/16 [3]对该系统进行进一步改良,由此于1970年推出了9 欧姆、5 升 LS3/5 系统。在该系统中,驱动单元呈“反转”布局:高音单元装在低音单元下方。BBC 先在内部少量制造了该款产品,并送到现场进行测试,结果大获成功,于是要求大量生产这一系统。

在制定新批次 LS3/5 的生产计划时发现,原来的驱动单元(即 B110 (A6362) 和 T27 (A6340))已经断货,而最新型驱动单元(即当时用于 KEF Coda 扬声器的 B110 (SP1003) 和 T27 (SP1032))的声学特性则因生产流程改进而略有变化。因此,BBC 必须根据这种最新驱动单元重新设计扬声器系统。1974 年初夏,LS3/5 改造完成,LS3/5A由此诞生 [4,5]。

在 LS3/5A 中,各驱动单元按正常方向安装,高音单元安装在低音扬声器上方,障板边缘采用衍射消除设计,另外为高音单元加装了一个有孔金属罩,既起到保护作用,又有助于提高声学响应。新型低音单元与箱体之间的耦合极为精细,以便将 LS3/5 的箱体音染维持在较低水平。依赖新型 8 欧姆驱动单元和改进型分频元件 FL6/23,该系统的额定输入阻抗从 9 欧姆提高到了 15 欧姆。

该系统先在 BBC 内部投入生产,后来向商业公司发放了生产许可,其中最为著名的非 Rogers Developments(后来更名为 Swisstone)公司莫属,该公司于 1975 年开始生产这种系统。1987 年 [6], LS3/5A 系统得以更新,这也是该系统唯一的一次更新:当时的 B110 SP1003 不断出现声学一致性问题,而这次更新就是采用专门设计的 SP1228 版本和新版分频元件 FL6/38 替换了该驱动单元,由此解决了这一问题。由于此番改进,改良版LS3/5A 系统的输入阻抗降到了 11 欧姆。驱动单元和分频元件的改造工作由 KEF 特殊产品部精心完成,以确保新版本在声学特性上与原版本毫无二致(在正常误差范围内),以便使新旧版本能够互换使用。正是在这个时候,KEF 开始提供匹配的分频元件 (SP2128) 和驱动单元套件,以保证最佳一致性。1991年,双线分频元件 (SP2195) 问世。

发放许可之后,LS3/5A 系统得到了大量生产:1975 年到 1993 年之间,Rogers 生产了 8 万多套,而 Spendor 和 Harbeth 则也分别从 1982 年和 1988 年开始,产量也十分惊人。其他许可生产商包括 Chartwell、Goodmans、Audiomaster (K.J. Leisuresound)、RAM、Decca 以及后来的 Richard Allan 和 Stirling Broadcast 等。1993 年,KEF 获得了生产许可,并生产了大约 4000 套系统。各公司生产的 LS3/5A 系统总计(单个扬声器而非扬声器对)超过 10 万套 [7],其中大部分出自 Rogers、Spendor 和 Harbeth。

1981 年,KEF 推出 Constructor 系列 CS1A 扬声器套件,其中包括 B110 (SP1003) 和 T27 (SP1032) 驱动单元和一个分频元件,该套件旨在达到 LS3/5A 的主观均衡水平,但其形状比 FL6/23 更简约。

尽管 KEF 基于 B110/T27 这种组合制造了Cresta(1967 年)、KEFKIT4(1969 年)、Cresta II(1970 年)、Coda(1971 年)、CS1/CS1A(1981 年)等多款两路扬声器,但直到1979年,KEF 生产堪与 LS3/5A 一较高下的产品,那就 Reference 101 扬声器。该系统采用 T27 (SP1032) 和 B110B (SP1057),箱体容积 6.7 升,其分频元件的复杂程度不亚于 LS3/5A,同时还采用了 S-Stop 保护电路。 Reference 101 的问世是与 KEF 在 20 世纪 70 年代开发的先进测量分析基础构架分不开的。
