创于1961年英国，以其高性能的创新扬声器在全世界高保真发烧友中间备受推崇，世界首家采用计算机辅助“总体系统设计”的扬声器制造商，因卓越的声学准确度而蜚声全球

KEF公司于1961年由RaymondCookeMBE(1925–1995)创办，总部最初设在肯特工程铸造厂(KentEngineering&Foundry，KEF便是由此得名)的一间Nissan棚屋中，这是梅德韦(Medway)河沿岸的一家金属加工厂，位于肯特郡梅德斯通市附近。曾担任BBC电气工程师的Cooke酷爱尝试新材料、新技术的实验，其目标就是生产出声学品质优良的产品，重现媲美原声演奏的自然音效。

自问世之初，KEF扬声器就凭借其开拓性的创新能力征服了业界。KEF成立之初的关键设计理念即是用合成材料制造驱动单元的振动膜和边缘。KEF的一款扬声器设计(即三路K1型扬声器)采用了箔加固、真空成型的聚苯乙烯振动膜和具革命性的T15高音单元，其振动膜乃用聚酯薄膜(美国将其称为Mylar，欧洲称为Hostophan)制成，这是一种新的高强度聚酯薄膜。

60年代20世纪60年代初，KEF推出了适应所有用途的综合产品系列，其中包括面向学校和公共机构的多用途Celeste便携式扬声器，此外还有K1和K2障板式扬声器——用户只要参照专用说明书即可将其自行组装到自有箱体中或进行“入墙”安装。后来，Cooke与BBC重新建立了合作关系，KEF由此成为LS5/1A监控扬声器的制造商，KEF一丝不苟、追求稳定品质的生产模式非常适合制造这种系统。为了开发出音质更加清晰的扬声器，KEF利用氯丁橡胶(一种合成橡胶)的固有性质，采用这种材料制造扬声器振膜的边缘，以便保持出色的中音音质。

20世纪60年代中期，KEF将一种新型低音/中音单元投入了开发之中。为了提升振膜的性能，Cooke及其开发团队着手研制了一种新型材料，即Bextrene。这是一种用木浆制成的轻型乙酸塑料薄膜，后来被BBC采用，用于制造LS5/5监控扬声器的低音和中音单元。Bextrene不但拥有必要的机械特性，而且化学性质十分稳定，能够在一般的温度和湿度变化范围内保持性能不变。用Bextrene制成的低音扬声器锥盆还可在广阔的频宽范围内形成稳定的音效，正是由于这些特性，这种材料才在开发成功后的数年之中得到了其他扬声器制造商的广泛应用。

在进行了一段时间的深入研发之后，KEF于1967年推出了一种新型的5英寸低音/中音单元(B110)，同时问世的还有?英寸的聚酯薄膜圆顶高音单元(T27)。随后，一款较大的8英寸bextrene锥盆低音单元(B200)于1970年上市。KEF规格齐全的驱动单元系列为设计师创造了大的灵活性。后来，这些驱动单元以多种多样的方式应用于数百万台扬声器当中——其中既涵盖了KEF在梅德斯通生产的扬声器，也包括全球众多其他制造商生产的产品。B110和T27在KEF新型Cresta书架式扬声器系统中得到了采用，同时还被BBC用于音质出众的微型LS3/5扬声器中。这种室外广播监控扬声器随后于1975年被改进为LS3/5A，这无疑是KEF与BBC通力合作主要成果。1967年，KEF还推出了Carlton监控扬声器系统，配有一只2.5英寸的bextrene圆顶高音单元，其后表面搭载一条33英寸长的声学抑制柔性管。三路Concerto于1969年面市。

20世纪60年代中期，一支规模不大、但才能出众的设计与生产工程团队(包括MalcolmJones，他后来成立了扬声器零部件供应公司FalconAcoustics)为实现RaymondCooke的设计愿景作出了不可磨灭的贡献。1968年，曾是Celestion和Goodmans工程师的LaurieFincham加入了这支团队，他在20世纪70到80年代KEF技术知识的发展过程中发挥中举足轻重的作用。70年代随着公司逐渐走红英国国外市场。借助新的革命性数字测试设备，KEF工程师们得以即时了解相关分频和驱动单元数据，为开发世界新一代音频设备作出了突出贡献。通过采用计算机生成的数据，KEF的工程师们得以为扬声器配对，误差控制在二分之一分贝之内，在音频技术领域里，犹如同卵双胞胎般的相似，KEF每一对扬声器成为了名符其实的匹配。该系列的产品型号包括Corelli、Calinda和Cantata，还有广受赞誉的Model104，这是堪与广播监控扬声器标准相媲美的家用扬声器。作为一款经典的高输出功率、高灵敏度系统，Model104同时也是KEF举世闻名的Reference系列推出的产品。

80年代在1980年的爱丁堡艺术节上，KEFReference系列出色的音质表现得到了充分认可。由克劳迪奥?阿巴多指挥的柏辽兹感恩赞即将在UsherHall举行，但演出使用的管风琴却在大约一英里开外的圣玛丽大教堂之中。管风琴演奏的音乐通过一条BBCFM无线电中继线路传送并用36个KEFReference105/2扬声器加以再现。20世纪80年代，KEF通过一系列技术革新打造出了Reference系列扬声器，凭借该系列，KEF以优良品质铸就的崇高盛誉从此更加光辉熠熠。KEF在这一时期的技术革新包括：耦合音腔低音载入技术，可提升低音性能；消力和驱动单元去耦技术，可消除驱动单元底座机械振动导致的箱体着色效应；共轭负荷匹配技术，有利于缓解放大器和KEF通用低音均衡器(KUBE)承受的电力负荷，可用小型箱体实现低音扩展。集这些技术于一身的便是1984年推出的Reference104/2。1985年，KEF推出了一系列车载音频产品，其中包括一款采用耦合音腔系统的低音扬声器，这种系统是为104/2扬声器开发而成。1987年又推出了入墙式Custom系列扬声器，该系列令人回想起60年代的K1和K2障板式扬声器。在不断拓展的扬声器市场上，Custom系列的诞生正式宣告，一个以应用为中心的崭新时代即将到来。1988年，KEF采用美国宇航局开发的新型钕/铁/硼磁材料制造出了一场颠覆业界技术传统的飓风——这便是Uni-Q驱动单元，这种新型钕/铁/硼磁材料的功率相当于普通扬声器磁体的十倍。此项重大创新使KEF工程师得以生产出可安装在低音单元线圈声学中心的小型高音单元。通俗说来，这种技术的优势就在于其显著扩展了室内聆听区域的范围。时至今日，Uni-Q仍是KEF的一大主要技术特色。3年后，设计人员在推出Corelli、Calinda和Cantata三款产品的过程中进一步完善了这种设计方法，使其发展成了一种新型扬声器开发模式——即计算机辅助“总体系统设计”。1年之后，也就是1977年，ReferenceModel105出世。这款产品采用独立的低音和中/高音箱体，可在整个音域内实现时间校准甚至音频扩散，更有四阶Linkwitz-Riley声学分频和与其声学性能相匹配的醒目外观，从此为家用扬声器树立了新的标准。同年，KEF被GoldPeak收购，崭新的创新篇章由此翻开，为KEF品牌的耀眼光环更添了一分眩目华彩。

1993年，KEF凭借100型中置扬声器在家庭影院市场再掀波澜。尽管价格不菲，但这款扬声器仍在发烧友中间引发了一股强劲的追捧狂潮，Uni-Q出色的弥散性能令这些追求音质的爱好者折服叹赏。次年，KEF成为推出THX认证家庭影院系统的公司之一，这种系统以低音扬声器/卫星扬声器设计理念为基础，配有垂直方向感突出的前置扬声器和偶极环绕声扬声器，在当时称得上是名副其实的“革命性”产品。随着20世纪的脚步继续向前迈进，KEF不断推出外观时尚而又经济实惠的新型产品，其中包括Q系列扬声器、60S/80C/30B家庭影院系统和屡获大奖的Coda7扬声器。1995年，远见卓识的KEF创始人RaymondCooke不幸与世长辞。然而，他给公司留下了强有力的指导方针，“质量、诚信、专注和创新”的核心价值观便是集各项方针的精髓所在。同年，采用第4代Uni-Q驱动单元的Reference系列Model4扬声器问世，该款产品在世界各地广受赞誉，并赢得到了行业媒体的一致好评。两年后，新一代的Q系列和新型Monitor系列产品面市，两款产品都是传承Cooke价值观的代表。

20世纪90年代后期，家庭影院市场不断发展，KEF工程师们也随之开始着手开发下一代经济实惠的高性能低音扬声器/卫星系统。他们造就的智慧结晶就是2001年推出的KHT2005系统，该系统推出了别具一格的“蛋形”卫星扬声器。铸铝箱体的出色质感，再加上Uni-Q超群的声学性能，这些品质为同类产品树立了新的标准。本世纪至今以来，KEF研发团队在高级声学、磁体和机械建模技术的应用领域稳步前进，积累了丰富的专业知识。这些技术(如有限元分析)使声学系统模拟精度达到了其他方法所无法企及的水平。例如，带有复杂振动部件的驱动单元现已可以实现原型虚拟和优化虚拟，这样就能在制造物理实体样品前考察多种方案。这种技术能力结出的硕果体现在各款KEF扬声器系统所采用的新型Uni-Q同轴共点单元之中：从4.5英寸的KHT3005系统(搭载棱纹锥盆和SST密封悬浮技术)到新的6.5英寸Reference系列Uni-Q系统(搭载优化几何形状和宽域扩散高音单元单元)，皆为KEF优秀技术能力的突出代表。

2005年，KEF向全世界公布了20世纪80年代末以来一直严格保密的ACE技术。经过综合研发之后，KHT9000系统向人们展示了一项惊人的技术成果，即将活性碳放入扬声器箱体可大幅增加箱体的有效内部容积——为小型箱体增强低音扩展的梦想由此化为现实。自此，扬声器行业终于找到了打破“扩展低音不能离开大型箱体”这一历史困咒的灵丹妙法。更重要的是，采用ACE技术的密封式箱体将低音扩展与出色过渡响应巧妙结合一处。此外，ACE技术也在KEF光耀现世的新成员——Muon舞昂扬声器中发挥着至关重要的作用，Muon舞昂不仅是该品牌新推出的产品之一，同时可能也是迄今为止声名旺盛的KEF扬声器。这款由KEF与英国设计师RossLovegrove联手打造的精品于2007年4月在米兰家具节上面世。如今，已迈入第50个年头的KEF仍在不断开发卓绝于世的扬声器产品。

Founded in England in 1961, with its high-performance and innovative speaker, it is highly praised among high fidelity fans all over the world. The world's first speaker manufacturer adopting computer-aided "overall system design" is famous for its excellent acoustic accuracy. KEF company was founded by Raymond cookembe (1925-1995) in 1961, and its headquarters was initially set up in Kent Engineering & amp; This is a metal processing plant on the Medway river near the city of medstone, Kent. Cooke, a former BBC electrical engineer, is fond of experimenting with new materials and technologies. His goal is to produce products with excellent acoustic quality and reproduce the natural sound effect comparable to the original sound performance. Since its inception, KEF loudspeaker has conquered the industry with its pioneering innovation ability. At the beginning of KEF, the key design concept was to make the vibration film and edge of the driving unit with synthetic materials. One of KEF's loudspeaker designs (i.e. three-way K1 speakers) adopts foil reinforced, vacuum formed polystyrene vibrating film and revolutionary T15 tweeter unit. The vibrating film is made of polyester film (Mylar in the United States and hostophan in Europe), which is a new high-strength polyester film. In the early 1960s, KEF launched a comprehensive product series suitable for all purposes, including multi-purpose Celeste portable speakers for schools and public institutions, as well as K1 and K2 barrier plate speakers. Users can assemble them into their own boxes or install them into the wall by referring to the special instructions. Later, Cooke established a new partnership with the BBC, and KEF became the manufacturer of ls5 / 1A monitoring loudspeakers. KEF's meticulous and stable quality production mode is very suitable for manufacturing this system. In order to develop speakers with a clearer sound quality, KEF uses the inherent properties of neoprene (a synthetic rubber), which is used to make the edge of speaker diaphragm to maintain excellent midrange sound quality. In the mid-1960s, KEF developed a new bass / midrange unit. In order to improve the performance of diaphragm, Cooke and its development team started to develop a new material, bextrene. This is a light acetate plastic film made of wood pulp, which was later adopted by the BBC to make bass and midrange units for ls5 / 5 monitoring loudspeakers. Bextrene not only has necessary mechanical properties, but also chemical properties are very stable, which can keep the performance unchanged in the general range of temperature and humidity. The woofer cone made of bextrene can also form a stable sound effect in a wide frequency range. It is because of these characteristics that this material has been widely used by other speaker manufacturers in the years after its successful development. After a period of in-depth research and development, KEF launched a new 5-inch bass / midrange unit (B110) in 1967, along with the? Inch polyester dome tweeter unit (T27). Subsequently, a large 8-inch bextrene cone bass unit (B200) was launched in 1970. KEF's full range of drive units creates great flexibility for designers. Later, these drivers were applied to millions of loudspeakers in a variety of ways - including the loudspeakers produced by KEF in medstone, as well as the products produced by many other manufacturers around the world. B110 and T27 are used in KEF's new Cresta bookshelf speaker system, and are also used by the BBC in the micro LS3 / 5 speaker with excellent sound quality. This kind of outdoor broadcast monitoring loudspeaker was later improved to LS3 / 5A in 1975, which is undoubtedly the main result of KEF's cooperation with BBC. In 1967, KEF also launched the Carlton monitoring speaker system with a 2.5-inch bextrene dome tweeter unit and a 33 inch long acoustic suppression flexible tube on the rear surface. Three way concerto was launched in 1969. In the mid-1960s, a small but talented design and production engineering team (including Malcolm Jones, who later founded the speaker parts supply company falconacoustics) made an indelible contribution to the realization of Raymond Cooke's design vision. Laurie Fincham, a former celesion and GOODMANS engineer, joined the team in 1968 and played an important role in the development of KEF technical knowledge in the 1970s and 1980s. In the 1970s, the company gradually became popular in the British foreign market. With the help of the new revolutionary digital test equipment, KEF engineers can instantly understand the relevant frequency division and driving unit data, making outstanding contributions to the development of the world's new generation of audio equipment. By using the data generated by computer, engineers of KEF have to match the speakers with an error of less than half a decibel. In the field of audio technology, they are like identical twins. Each pair of speakers of KEF has become a real match. The product models of the series include Corelli, Calinda and cantata, as well as the widely acclaimed model 104, which is comparable to the standard of broadcast monitoring loudspeakers for home use. As a classic high output power and high sensitivity system, model 104 is also a product of KEF's world-famous reference series. At the Edinburgh Art Festival in 1980's, kefreference series's excellent sound quality performance was fully recognized. Berlioz, led by Claudio Abbado, is about to hold Thanksgiving at UsherHall, but the organ used in the performance is in St. Mary's Cathedral about a mile away. The music played by the organ is transmitted through a bbcfm radio trunk line and reproduced with 36 kefreference105 / 2 speakers. In the 1980s, KEF created a series of reference loudspeakers through a series of technical innovations. With this series, KEF's high reputation of excellent quality has become more brilliant ever since. KEF's technical innovation in this period includes: coupling cavity bass loading technology, which can improve the bass performance; force dissipation and drive unit decoupling technology, which can eliminate the box coloring effect caused by the mechanical vibration of the drive unit base; conjugate load matching technology, which is conducive to alleviate the power load borne by the amplifier and KEF universal bass equalizer (Kube), which can be realized by small box to expand the bass 。 The combination of these technologies is reference104 / 2, which was launched in 1984. In 1985, KEF launched a series of vehicle audio products, including a bass speaker with a coupled cavity system, which was developed for 104 / 2 speakers. In 1987, a series of custom loudspeakers were introduced, which recalled the K1 and K2 barrier plate loudspeakers in the 1960s. In the expanding speaker market, the birth of custom series officially announced that a new era centered on application is coming. In 1988, KEF produced a hurricane that overturned the industry's technological tradition by using a new neodymium / iron / boron magnetic material developed by NASA - this is the uni-q drive unit. The power of this new neodymium / iron / boron magnetic material is ten times that of ordinary speaker magnets. This major innovation enables KEF engineers to produce small tweeter units that can be installed in the acoustic center of the bass unit coil. Generally speaking, the advantage of this technology is that it significantly expands the range of indoor listening area. Today, uni-q is still a major technical feature of KEF. Three years later, in the process of launching Corelli, Calinda and cantata products, the designers further improved this design method and developed it into a new speaker development mode, namely, computer-aided "overall system design". One year later, in 1977, reference model 105 was born. This product adopts independent bass and mid / treble boxes, which can achieve time calibration and even audio diffusion in the whole sound range. Moreover, the fourth-order linkwitz Riley acoustic frequency division and the eye-catching appearance matching with its acoustic performance set a new standard for home speakers. In the same year, KEF was acquired by goldpeak, which opened a new chapter of innovation, adding a dazzling luster to the brand of KEF. In 1993, KEF made another wave in the home theater market with its 100 type mid speaker. Although the price is not cheap, but this speaker still caused a strong wave of popularity among fans, the excellent dispersion performance of uni-q makes these fans of pursuing sound quality admire. The next year, KEF became one of the companies that launched the thx certified home theater system. Based on the design concept of subwoofer / satellite speaker, this system was equipped with front speakers and dipole surround speakers with outstanding vertical sense, which at that time was worthy of the name of "revolutionary" product. As the pace of the 20th century continues to move forward, KEF continues to introduce fashionable and affordable new products, including Q series speakers, 60s / 80C / 30b home theater system and award-winning coda7 speakers. In 1995, Raymond Cooke, the visionary founder of KEF, died. However, he left a strong guideline for the company. The core values of "quality, integrity, focus and innovation" are the essence of all the guidelines. In the same year, the reference series model4 loudspeaker with the 4th generation uni-q driver unit was launched, which was widely praised around the world and won the unanimous praise of the industry media. Two years later, a new generation of Q series and new monitor series products were launched, both of which are representatives of cookie values. In the late 1990s, with the continuous development of home theater market, KEF engineers began to develop the next generation of affordable high-performance bass speaker / satellite system. The wisdom they created was the kht2005 system launched in 2001, which launched a unique "egg shaped" satellite speaker. The excellent texture of cast aluminum box and the superior acoustic performance of uni-q set a new standard for similar products. Since this century, KEF R & D team has made steady progress in the application fields of advanced acoustics, magnet and mechanical modeling technology, and accumulated rich professional knowledge. These techniques (such as finite element analysis) make the simulation accuracy of acoustic system reach the level that other methods can not match. For example, the driving unit with complex vibration components can now realize prototype virtual and optimization virtual, so that multiple schemes can be examined before manufacturing physical samples. The achievements of this technical capability are embodied in the new type of uni-q coaxial common point unit adopted by various KEF speaker systems: from the 4.5-inch kht3005 system (equipped with rib cone basin and SST sealed suspension technology) to the new 6.5-inch reference series uni-q system (equipped with optimized shape and wide range diffusion tweeter unit), all of which are outstanding representatives of KEF's excellent technical capabilities. In 2005, KEF released ace technology, which has been strictly confidential since the late 1980s, to the world. After comprehensive research and development, the kht9000 system shows us an amazing technical achievement, that is, putting activated carbon into the speaker box can greatly increase the effective internal volume of the box - the dream of enhancing bass expansion for small box becomes a reality. Since then, the speaker industry has finally found a magic way to break the historical curse of "expanding bass can't leave the large box". What's more, the sealed box with ACE technology combines bass expansion with excellent transition response. In addition, ACE technology also shines new success in Kef
