一个月前我的音箱曾经出过右边箱有噪音并且忽大忽小甚至无声的情况,我排除了cd和信号线的问题,打开功放清洁了内部和所有接头,开机正常直到今天,又出现同样问题,麻烦版主看看是否功放有问题,或者是其他什么问题。非常急切,谢谢!

前阵子,本人好不容易搞了一对音色比我原来那对破箱好得多的KEF105.4音箱一对,但痛苦的是对它一点对不了解,即不知道是那个时期产的,也不知道原来的价位好何,到底用什么功放更能发挥它的潜力也不懂,请各位大佬教教小弟吧,指点指点一下吧!!!

(作者:forever 时间:2003-03-14 18:45:37)- 10年前的箱子,应该不错的。中高音看样子是和我现在用的107.2一样的,声音应该也差不多吧。The acclaim given to Model 105 created a demand for a system capable of similar performance from a smaller enclosure.
Model 105.4 maintains the standards of truthful reproduction and stereo perspective with higher efficiency and only slightly reduced bass response.
Model 105.4 Features
Flat frequency response: 60Hz to 22Khz.
Contoured mid and high frequency enclosures reduce colouration off-axis.
Visual indication of optimum listening area.
Variable system geometry extends choice of listening position.
Novel bass loading technique gives higher efficiency and greater power handling capacity.
Electronic protection, S-STOP, protects against overload and fault conditions
Pairing of systems guarantees sensitivity and frequency response matched to within 0.5dB.
Model 105.4 Benefits
At any volume output up to concert hall level, MODEL 105.4 offers realistic and accurate reproduction of the input signal and a remarkable stereo perspective over a wide area.
MODEL 105.4 comfortably handles the bursts of peak power essential to realistically reproduce the dynamic range of any musical instrument. Even when using amplifiers of up to 200 Watts capable of delivering the full short-duration dynamic range captured by modern recording techniques, the system cannot be damaged. A unique self-powered protection device ensures that short peak power input levels, excessive or thermal overload, cannot destroy vital components or impair calibration.
Every MODEL 105.4 employs a 25mm soft dome tweeter with a 110mm mid range unit located in separate enclosures, and two 200mm bass units combined through a complex 19 element dividing network.
The two identical bass units are arranged to work together over the lower part of the frequency range ensuring reduced distortion and power handling capability.
To obtain an even distribution of sound, a filter system progressively reduces the output of the lower bass unit (above 20Hz) so that at the crossover frequency to the mid range unit, only one bass unit is functioning.
The close tolerance needed to realise the full potential of the MODEL 105.4 design are maintained in production by a unique computerised matching procedure so that every pair of MODEL 105.4’s is matched in sensitivity and frequency response to within 1dB of the original laboratory prototypes.
A new bass loading technique resolves the problems of the complex interaction between electrical, mechanical and acoustic characteristics to achieve greater efficiency than an infinite baffle and better transient performance than a reflex enclosure.
The head assembly may be adjusted vertically and horizontally to direct the optimum response achieved within a listening window 40º wide and 10º high to the desired listening position. An indicator light is used to identify the best listening area.
A self-powered electronic circuit called S-STOP protects the loudspeaker from the effects of any accidental overload, and automatically re-connects the full input signal only when the overload is removed.
MODEL 105.4 incorporates a peak level indicator pre-set to correspond with the rated output of a 200 Watt amplifier. should the dynamic range of the input signal make excessive demands on the capability of the amplifier such that ‘clipping’ and audible distortion may occur, the indicator will light.
