So what do we listen to when judging the sound quality of a speaker or an overall audio system? The first is the overall pitch balance. The bass, midrange, and treble portions of the audio spectrum should sound balanced, with no too loud or too low portions. If the bass is set too high, the sound from the speaker will be too "thick" and "dull"; if the treble is too low, the sound will lose "angry". If the midrange is set too low, the sound will feel a bit "scattered"; if it is set too high, it will sound a bit "sharp".
The extension of the bass is related to the size of the speaker, while the treble should restore the ultra-high frequency and give the "real" feel to the real sound without producing the slightest exaggeration. Obviously, subjectivity plays a role in describing the sound, but this is part of the speaker designer's skills, the purpose of which is to correlate the perception of the sound with the response test results and to fully understand what adjustments should be made in the response to improve.

Next we will listen to the sound quality. We hope that the bass can be "pure", "transparent", "tight", "deep" and have a good "response speed"; you must not think of some seemingly random changes to the low frequency response to make the sound quality of the speaker It is dull and boring by the excitement. The intermediate frequency should be open and delicate, without the texture of “obtrusion†or “hardâ€, which makes the sound more natural and the sound is moving. The treble should be naturally transparent and not too "sharp", "stabbing" or "pretending". The sound should not have any noticeable sound or distortion, which may have a negative effect on the reproduction of the sound.
Stereo panning should be accurately generated between the speakers. Instruments should not change the representation position when playing different notes. Instruments and vocals set at the center of the sound image should have a thick and realistic effect, and should not be unnaturally transitioned when the listener moves back and forth. Symphonies and choruses should have a true physical proportion, as well as good reverberation and acoustic characteristics of the recording venue; the listener should be able to experience the realism of a complete chorus composed of different vocals and instruments.
Finally, let's talk about the dynamics, that is, the ability of the speaker to accurately restore the recorded volume of the music without significant distortion. This refers to not only being too heavy or harsh when playing loud sounds, but also the ability to reproduce the subtle changes that are contained in the most beautiful playing music.
When all of this fits together, we get really great speakers. Designing for cost targets is a very important consideration for most of our speakers. We will do our utmost to provide our customers with quality products that combine the above qualities.
In general, our pursuit of speaker quality will not change depending on the type of speaker application – we strive to ensure that the KEF concept is implemented in all of our designs. Of course, in some categories we will pay special attention to certain aspects.
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
