About the selection of speaker crossovers

1. Determine the type of crossover according to the composition of the speaker unit of the speaker

Whether the speaker is a high-pitch two-way or a high-pitch bass three-way frequency, it should correspond.

2. Three-way converters, there may also be special speaker designs, such as high, medium, low, and bass three-way four-way units, etc., and customized crossovers may also be required;

2. Determine the crossover according to the speaker power

The crossover has a power range, such as 5 10W, 10 30W, 50 200W, etc. The suitable power of the crossover must be greater than or equal to the speaker power but does not need to be too large, otherwise it may damage the crossover or the audio power is excessively consumed on the crossover, and the high-power crossover used in the small speaker will increase the capital investment;

3. Determine the crossover point of the crossover point of the frequency divider according to the cross frequency of the speaker unit

For example, the frequency range of the speaker woofer is 45Hz 1200Hz, the midrange speaker is 900Hz 5000Hz, and the tweeter is 3500Hz 22000Hz, and the crossover bass crossover point is 1000Hz 1100Hz, and the treble crossover point is 4000Hz 4500Hz.

It should be chosen, because the woofer contains a treble component and will not be distorted; The tweeter contains a bass component, which will cause distortion.

The crossover itself does not need to calculate the crossover point, and the performance indicators of the speaker are given by the manufacturer.

If you make your own crossover, you need to calculate the capacitance capacity, coil size, number of turns, and attenuation resistance. It is difficult to meet the standard of self-made frequency divider, if the requirements are not high, it is better to use a capacitor to divide the frequency, you can change the capacitor and try to come until you are satisfied.

I am a pair of dual 12 speakers, how should I match the crossover?

It is necessary to provide speaker parameters, otherwise it is not easy to choose!

Specializing in the development of speaker crossovers, I don't know how to consult and communicate at any time!

Basically, there are crossovers, but the cost, structure, and materials of the crossovers are different, because directly connecting the woofers in parallel or series is easy to burn the tweeters.

The crossover of non-full-range speakers adopts a series of crossovers according to the cost from low to high:

The cheapest single capacitor or single resistance frequency divider: the popular passive two-way bookshelf box, the use of single capacitor frequency division is the majority, the cost is only a few cents, that is, the power amplifier is directly connected to the woofer, and the tweeter is connected in parallel with the bass through a non-polar capacitor;

Some speakers that use piezoelectric tweeters use single-resistance crossover, and the tweeter string is connected in parallel with the bass with a high-power and low-resistance resistor;

2.The mid-range power divider using ordinary materials is divided into one order, two orders and three orders, and the materials are iron core inductors, audio non-polar capacitors and high-power resistors, and the ** of a single frequency divider is between 2 and 10;

3.High-end power dividers using audiophile components are also multi-staged, using high-grade materials such as air-core inductors and audiophile capacitors, the cost is very high, and some excellent air-core inductors are just a few dollars a piece, and the unit price of such crossovers is more than 20.

The best way to choose the sound quality of the crossover is:Drive the corresponding speakers separately, and the fidelity of the sound field restored by multiple speakers will be higher and cleaner.

For amplifiers without crossover, only one full-band audio signal is output to drive the speaker. Truly full-range high-quality speakers are very rare, with either enough bass and a lack of treble components, or rich mid-to-high tones and a lack of low frequencies.

In short, it is difficult to obtain high sound quality when the amplifier directly drives a speaker. The structure and material of the speaker also determine the frequency band in which the speaker works, so the speaker has a difference in bass, midrange and treble.

Each speaker has its own area of expertiseTherefore, dividing the audio signal output by the power amplifier into three frequency bands or two frequency bands and driving the corresponding speaker separately will achieve satisfactory results.

The function of the crossover for the separation of frequency bands is:

After the frequency band is separated, the bass is not muddy, the midrange is full, and the treble is slender.

Therefore, today's loudspeakers are equipped with a crossover device, either with a crossover board or a simple crossover with a non-polar capacitor. The crossover quality and listening effect of the wheel, the crossover board is better, and a crossover point can be specially set according to the structure of the speaker unit cabinet. Therefore, the more expensive the divider, the better, but the right one is the best.

With a crossover, the sound system can only be reasonably displayed, and the sound quality of the sound without a crossover will be held back, just like no matter how good the sound is, a pair of garbage speakers will not make a good sound.

If you want to get high sound quality, you must first have a high-quality sound source, front, and secondly, the quality of the power amplifier. If the quality of the audio source is poor, then no matter how good the amplifier is, it will not release good sound, but only infinitely amplify the shortcomings of the audio source.

Yes, it is related.

The crossover refers to distinguishing the sound signals of different frequency bands, amplifying them respectively, and then sending them to the speakers of the corresponding frequency bands for replay. In the case of high-quality sound reproduction, electronic crossover processing is required. The crossover is the "brain" of the speaker and is crucial to the quality of the sound.

The ** signal output by the power amplifier must be processed by the filter element in the frequency divider to let the signal of a specific frequency of each unit pass through. It is necessary to scientifically, reasonably and rigorously design the frequency divider of the speaker, in order to effectively modify the different characteristics of the speaker unit, optimize the combination, make each unit develop its strengths and avoid weaknesses, and give full play to its due potential, so that the frequency response of each frequency band becomes smooth, and the sound image phase is accurate, so that the high, medium and low tones can be clearly layered, coordinated, bright, comfortable, broad and natural sound quality effect.

What is the best frequency speaker? Hello dear, generally the speaker with more frequency division is better. At present, most of the full-range speakers on the market are two-way and three-way.

What is the crossover, if the frequency response range of a full-range speaker is 100Hz-16kHz, it is difficult for a speaker to show such a wide frequency response, so there is a crossover, for example, the crossover point of the two-way frequency is, that is, the woofer is responsible, the tweeter is responsible, so that the high and low frequencies can be taken into account. But there are also disadvantages, just in the vicinity, because this thing is an analog quantity, can not be done very accurately, so the sound effect is relatively poor in the vicinity, and similarly, the three-way or even the four-way frequency will be more of this situation. So it's not a good frequency, it's a measure of technical ability and degree.

Speaker electronic crossover is better. Electronic frequency division is the circuit topology design that precedes the promotion of the frequency division circuit to the amplification circuit. Electronic frequency division (or active, active frequency division) networks have the following advantages:

1. The transient response is improved.

2. The working frequency band of each amplifier is narrowed.

3. The possibility of low-frequency overload is reduced.

4. Increased dynamic range.

5. The intermodulation distortion is small.

6. The sensitivity of each unit is easy to control.

As long as the speaker has a two-wire crossover binding post, it can be connected to the power amplifier of electronic crossover, mainly the power amplifier separates the high and low bass, and uses their independent amplification circuit to promote the sound of different units, so the cost is high! Electronic frequency division has advantages such as good phase characteristics, but has high requirements for the straightness of the frequency response of the unit, while the ordinary frequency division (power frequency division) can make up for the defects in the frequency response of the unit by adjusting the parameters of the frequency divider! Therefore, it is not possible to say that the electronic frequency division is out of the blue, and it is wisest to choose the right one for yourself according to economic strength!

For example, my multi** speaker uses Huiwei D1010MKII08 is an electronic crossover, but the low frequency is limited by a low single caliber (4 inches), and the low frequency is still insufficient, and there is still a slight phase error at the crossover point (the straightness in the effective frequency response is good!). The digital taste is much more convergent than speakers at the same price! ）！

The sweetness of the sound, the high-end and low-end extensibility are still hard to compete with my low-grade HIFI system (Huiwei, BADA amplifier)! That is to say, if the quality of the ordinary frequency crossover speaker unit is excellent, the speaker design is excellent, and the sound quality of the general division amplifier is not necessarily inferior to the general design of the electronic frequency crossover! It is best to use a fever system, and the computer audio should not be played too high-end!

Full-range speakers and crossover speakers have their own advantages, mainly depending on what you are using. Full-range speaker,A speaker made of only a full-range speaker is called a full-range speaker,The biggest difference between it and an ordinary speaker is that it has only one speaker,Ordinary speakers generally use a crossover internally。

Separate the high, mid, and bass, and the horns range from 2 to n. Full range, as the name suggests, refers to a wide range of frequencies and wide coverage.

Advantages: point sound source, so the phase is accurate; The timbre of each frequency band tends to be the same, which is easy to bring better sound stage, image and instrument separation.

and hierarchies. Due to its strong expressiveness in the middle frequency stage, it happens that most of the sounds emitted by people are mainly in the middle frequency, therefore, the full-range speaker is very suitable for listening to the human voice, and the distortion rate in the ear is low, and the performance of the human voice is quite full and natural.

In crossover speakers, each frequency band is sounded by a separate unit, so that each unit can work at its best. The extension of high and low frequencies is easier to achieve, and the independent MF unit can bring extremely high playback quality, and the overall electro-acoustic conversion efficiency is high.

Full-range speaker: A speaker made of only a full-range speaker is called a full-range speaker, the biggest difference between it and an ordinary speaker is that it has only one speaker, and ordinary speakers generally use a crossover to separate the high, medium and low tones internally, and the speakers range from 2 to N. Crossover speaker, refers to its frequency range is phased, and the signal frequency is more focused.

Crossover speakers are usually built-in with dual-frequency speakers or tri-frequency speakers or more. There is a crossover in the crossover speaker, which can split different audio signals into several parts, and transmit different frequency band signals to the corresponding speaker through the crossover.
