In the speaker system, the speaker is mainly divided into two categories, one is the full frequency speaker, the other is the frequency division speaker,coaxial speaker is a form of frequency division speaker.So what exactly is a full-frequency speaker? What is a coaxial speaker again? What are the different advantages,disadvantages and the differences?
What is a full-frequency speaker
Full frequency speaker: is only use a full frequency speaker, only one horn. In fact, a horn could not cover all spectrum. Generally speaking, full frequency, in fact, is broadband, that is, the frequency range is relatively wide. The full frequency horn cover the frequency range is 200 -10KHz, with the acoustic technology progress in recent years, now general full frequency horn can reach 50-25KHz frequency range, some speakers of low frequency can go down to 30Hz.
Human ear can hear the frequency range is 20-20KHz, Full frequency speakers can basically cover the human ear,can hear all the frequency range of sound.But unfortunately, the current market full frequency speakers, although it is full frequency, in fact, its frequency is mostly concentrated in the middle of this category, in the bass and treble performance are slightly weak, so hear the sound is relatively flat, three-dimensional sense is not so strong.
Full-frequency speaker’s features / advantages
Point sound source, thus accurate phase; each frequency band timbre tend to coincide, easy to bring better sound field, resolution, instrument separation and hierarchy. Because of the performance of the frequency stage is strong, just the sound of the people is mostly medium frequency, so, the full frequency speaker is very suitable to listen to the voice, and the distortion rate of the ear is low, the performance of the voice is quite full and natural.
Full-frequency speaker’s disadvantages
To meet the needs of different frequency band, the design and final performance of each frequency band will be constrained. The extension at both ends of the high and low frequencies is relatively limited, and both transients and dynamics are relatively discounted.
What is a coaxial speaker
Coaxial speaker: it is a special form of frequency division speaker, it is the loudspeaker of speaker is placed skillfully in the center of medium bass diaphragm, make medium bass unit and high pitch unit are located on same axis, front look is two concentric circles, therefore the acoustic center that can ensure high, bass is same point, reason calls coaxial sound box accordingly.
We often hear a friend to coaxial speaker and full frequency speaker confused, of course, these two kinds of speakers have their common ground, they are to build a point sound source, but coaxial speaker structure is different, two speakers in the frequency state, and have their own division of labor, respectively responsible for the operation of treble and bass.
Coaxial speaker features / advantages
The design structure and form of coaxial speaker can be said to be painstakingly, it has the characteristics of high phase fidelity of full frequency speakers, to achieve more natural sound output in the form of standard point sound source. At the same time, in the listening sense, also has the strong expression of the frequency distribution speaker in the high and low sound, bass realistic cohesion, large energy density, transient better can receive can put, make its sound level more distinct, the sense of detail is more prominent.
