What is a cabinet speaker?

The box speaker is a box-shaped audio amplifier , also known as a box, which is no longer strange to everyone, especially those who have a hobby of learning audio equipment.

Currently on the market there are many different types of cabinet speakers, but they all work on the principle of making the air move based on the control of electrical signals to create sound waves that propagate in the air and they will affect the listener’s ear to help the listener enjoy the sound.

Basic structure of cabinet speakers

Driver

Also known as navigators , It is responsible for converting electrical signals into sound waves through the movements of the diaphragm. The driver of a good quality cabinet speaker consists of 4 types to be suitable for each different sound range:

• High frequency drivers are used to represent high frequency sounds.
• Mid-frequency drivers they best convert the frequencies that humans can hear.
• Subwoofer driver it shows the subwoofer frequencies to help create the best bass.
• The full-range driver will have the effect of showing all three high-low and mid-range tones.

Echo hole

The reverberation hole, also known as the bass reflex , was created to solve the problem of small drivers and enclosures and increase low-frequency reproduction.

Usually this hole is usually designed in the form of a double hole or a double hole that is reflected in the front or rear of the speaker.

Speaker box

Speaker enclosures are actually speaker enclosures known to users with factors such as thickness, coating type, size, manufacturing materials, etc. Not only are they located on the outside, they have the effect of protecting the speakers from damage. Damage comes from the environment, but the speaker cabinet also has a huge impact on sound quality.

The space inside has a certain importance to the operation of the speaker. In particular, its structure is the place to contain all the key components such as the tweeter, bass, and crossover circuit of the cabinet speaker.

Most speaker cabinets on the market today are made of wood with very dense and long walls to minimize speaker vibrations as well as help the device produce the best sound.

For mid-range speakers, MDF is the preferred material, which not only reduces vibration but also has a very reasonable price.

Wiring Jack

For the best quality connection, cabinet speakers must have their own wiring port so that they can be easily upgraded to higher-end speaker cables. One of the speaker improvements is that the connection positions are capable of connecting ropes or wires using their own speaker jacks (standard Speak On jack neutrik).

Usually speakers use their own speaker jack (standard Speak On jack neutrik) to connect to an amplifier or power amplifier to help the signal be transferred to the speaker in the best way before being processed by the speaker. The wiring jacks are usually located on the back of the speakers.

crossover circuit

When it comes to the crossover circuit, we are talking about the part that separates the signal channels , into different audio bands, for each suitable speaker.

This crossover circuit is usually located in the speaker cabinet, it is understood as the audio signal processor before the sound is filtered to the drivers. This set of parts, will help the sounds to be divided in the best way, so as not to absorb sound or overlap, when emitted.

Accessory

To make it easier and simpler to install cabinet speakers, manufacturers have created accompanying parts such as cabinet speaker legs, cabinet speaker cover, cabinet speaker rack, …

Although they are only external parts, you need to find out carefully, because if you choose the wrong one, it will greatly affect the installation as well as the sound quality. Best, to be sure, should look to people who specialize in the field of sound and light to listen to their advice.
