The PreSonus AIR speaker system opens up new possibilities for music events. The perfect combination of high-quality sound, easy setup and portability makes PreSonus AIR models a truly affordable and versatile solution.

The AIR series consists of three models of satellites with 10, 12 and 15 inch woofers and two direct radiating subwoofers with 15 and 18 inch speakers. The speaker systems are equipped with modern sound processors that display settings on an LCD display. While many manufacturers have completely switched to D-class switching amplifiers, PreSonus believes that their quality is not sufficient for transmitting the high-frequency spectrum of sound and for amplifying low power of several hundred watts, classic class A/B amplifiers can be successfully used, ideally transmitting high-frequency components of music. As a result, AIR acoustics use a hybrid solution: a D-class amplifier works only with a low-frequency speaker, and an A/B class of amplification is used with a high-frequency driver. This improves the system's HF impulse response, simplifies system setup, and ultimately delivers clear, detailed sound.

In addition, PreSonus carefully thought out the appearance of the speakers. These are compact and lightweight cases in a universal satellite monitor design, with integrated carrying handles and hanging points. The satellites are equipped with two-position cups for installation on an acoustic stand or subwoofer-satellite boom. The glass in two positions allows you to install speakers with the direction of the sound field parallel to the floor or with a tilt of 7.5° downward, into the hall, if they are installed on stage. Subwoofers of the AIR series are immediately equipped with wheels, which can be installed in case of frequent outdoor events.

TO interesting features The PreSonus AIR series includes special settings in subwoofer processors for constructing two types of cardioid arrays: Cardioid, when two subwoofers are installed on top of each other and one is rotated 180°, and Endfire, where two subwoofers are installed one behind the other at a certain distance. Cardioid low-frequency arrays allow you to generate a directional wave in the direction of the audience and reduce its intensity in the direction of the stage.

Presented in a fairly large assortment. This equipment differs from each other in scope (instrumental, concert, studio and others), according to technical specifications, body shape and many other qualities.

Most important parameter The first thing to consider is the number of "lanes" in the system. According to this criterion, one-, three- and two-way acoustics are distinguished. How they differ from each other and which system is better, we will try to answer in this article.

Sound frequency

The human hearing organs are capable of detecting frequencies from 20 to 20,000 Hz.

Therefore, the quality of music directly depends on the ability of the equipment to create clear sound waves in a given range. For this purpose, they began to include speakers that reproduce exclusively low (20-150 Hz), medium (100-7000 Hz) and high (5-20 thousand Hz) frequencies. In this regard, the following appeared:

1. Single-way systems, where the entire frequency range is produced by one speaker.
2. Two-way acoustics, which have two speakers: one for playing music at medium and low frequencies, the second - only at high frequencies.
3. Three-band equipment - a separate “column” is responsible for playing sounds in each range.

There is equipment with a large number of bands, where each speaker reproduces sound in a certain way. Two- and three-way systems are the most popular - they are the most affordable and provide excellent sound quality.

Advantages of two-way acoustics

Two-way Acustic systems are most popular among motorists.

They provide optimal sound quality while also being at an affordable price. Due to the development of technology, two-way is being replaced by three-way equipment, but it is still common due to its advantages:

1. Simple design for easy installation and configuration.
2. High degree of coherence between speakers, resulting in improved sound quality.
3. Maximum natural, “live” sound.

In two-way equipment there are only two speakers - LF and HF. The woofer reproduces sounds in the low and mid ranges, and the tweeter only reproduces sounds in the high range. Because of this, simple separation filters are required for the system to operate.

Features of three-way equipment

Three-way acoustics differ from the already described system in that they have better sound. The equipment in such systems is equipped with a midrange speaker, which carries so-called “spatial” information and creates surround sound. In addition, thanks to the separation of duties, the equipment has become more compact.

The negative quality of three-way systems is their high price. It is two to three times higher than that of two-way acoustics. Moreover, three-way acoustics implies the installation of crossovers - complex frequency filters. To set up such equipment, you must have excellent hearing, otherwise you will not be able to achieve consistency from the speakers.

Differences between speaker systems

Any speaker system consists of speakers (midrange, bass and tweeter), filtering equipment, signal amplifiers, audio cables and input terminals. Filter devices are responsible for separation sound signal for several ranges. A two-way acoustics filter divides frequencies into two “sections” - up to 5-6 thousand Hz, and above 6 kHz. Three-way devices are usually equipped with crossovers - adjustable frequency filters that divide the sound range into three sections.

All acoustic equipment can be active or passive. In the first case, each speaker is equipped with a separate signal amplifier. This solution facilitates matching of emitters and reduces the overall cost of the system. However, at the same time, the complexity of maintenance, installation and initial configuration increases. Separate amplifiers most often complement a set of three-way devices.

Coaxial and component speakers

How a three-way or two-way will sound largely depends on the type of speakers, which can be coaxial or component. The former are a single monolithic structure that combines high, medium and low frequency emitters. This solution makes the sound highly targeted. Therefore, such devices are used as a supplement and mainly in small cars.

Component speakers are emitters that can be placed in different places. Thanks to this, it is possible to achieve surround sound, but the process of installing equipment is complicated. In addition, when incorrect installation the sound stage will be quite uneven. installed in cars with a spacious interior.

Question of price

As noted earlier, two-way acoustics will cost much less than installing three-way equipment. This is due to two reasons:

• less equipment - only two speakers, a maximum of two amplifiers and one filter are required;
• simple installation - you can assemble such a system yourself, having basic knowledge in the field of electricity.

Three-way systems include more complex equipment, the cost of which is significantly higher than the price of conventional devices. In addition, if you decide to install such acoustics, you will have to seek the help of professionals - without special measuring devices and fine hearing, the installed system will sound the same as two-way acoustics. This is the main answer to the question of how two-way acoustics differ from three-way ones.

2-way car speakers

The two-way acoustic system has long been very popular among motorists who value good sound. Today, three-way acoustics are an obvious competitor to this acoustics, but supporters of the old system still respect it and are not going to change it for anything.
Why a two-way speaker system is better and why it is so loved, we will find out from this article, where, among other things, instructions will be given on how to quickly install it in a car.

Advantages of two-way acoustics

As is known, all types of bandpass acoustics are divided into special classes. IN in this case we are talking about component and .

Coaxial acoustics

• It implies the presence of two heads installed in the speaker housing. Advantages - low cost and ease of installation.

Component acoustics

• Two speakers are combined into one complete system, reproducing low and high frequencies. The cost of such a system is much higher, which is understandable.

Front and rear acoustics

As you know, it is still customary to install speakers in a car depending on the direction of the sound.

• – this is, in principle, an installation in regular places speakers, that is, in the front doors. Everything would be fine and there would be no problems if the standard seats were made in accordance with high-quality speakers.
  But the fact is that on almost any car these very places intended by the manufacturer for installing speakers are very small and are designed for small-sized speakers.
• Front acoustics take over the most important function– creating the right sound stage in the car. At the same time, its installation involves the use of special door linings followed by strong fastening of the speakers.
• Frontal acoustics usually involve installing speakers in the upper parts of the front doors.

• To achieve the best sound effect, 2-way speakers should be mounted so that its elements are as close to each other as possible. This means installing the woofer in the door, and the tweeter on the pillar or dashboard of the car.

Advantages of front acoustics:

• Installation will be quick and easy.
• In the case of a 2-way system, there will be practically no difficulties during installation.
• On the other hand, installation in a door implies the absence of a housing for the speaker, which can negatively affect the sound quality. In this regard, craftsmen come up with various and original ones that enhance the sound effect from the speakers.

As mentioned above, the main thing in a car is the rear acoustics. As for this system, it will serve as an additional sound effect.
So:

• The use of rear acoustics is justified, because the speakers in this case improve the overall background sound, making the sound picture much deeper.
• 2-way speakers sound better, of course, from the front, but also from the back in the trunk or on an acoustic shelf, their midrange frequencies will sound good.
• Installing rear speakers also involves making a special acoustic shelf, which helps better sound speakers.

Installation of 2-way acoustics

So, as it became clear, full installation 2-way acoustics in a car means using it both front and rear.

Front doors:

Note. For installation in the front doors, it is advisable to use 16 cm speakers.

• We purchase or make our own podiums for speakers.

Note. It is worth noting that the podiums themselves are unlikely to provide strength to the speakers. Therefore, a board is made separately for the podiums or special linings made of chipboard or plywood are placed under them.

• We are modifying the doors, increasing the dimensions to accommodate the installation of 16 cm speakers. Also at this stage, a strong support is installed, which must be firmly screwed to the metal part of the door.
• We create an acoustic volume by sealing the door openings with masking tape. We cover the tape with fiberglass cloth, which, in turn, is impregnated with epoxy glue.
• If you make the podiums yourself, you will first need to cut out rings with 4 ears from plywood. These same ears will be needed to attach the podium to the door.
  Then we make 2 intermediate rings for each podium and assemble everything together, also using spacers.
• We firmly screw the podiums to the door.
• We cover the door with vibroplast.

Note. The crossover can be installed next to door handle, because he will be quite free to be in this place (depending on the car model).

The instructions given above will help you avoid making mistakes when choosing and installing this acoustic system yourself. During the installation process, it is recommended to study photo and video materials.
As you know, the price of installing audio systems in a car from professionals is always high, so there is a reason to learn how to do everything yourself.
