The acoustic boxes were made for the optimization of the sound. What is essential for total use of home theaters, musical instruments and music players. Usually built in wood or plastic, with an opening for installing the high-speaker, it is designed to prevent the waves of sound to be mixed and manage interference in quality. There is a big improvement in the acoustics boxes reproduction. Your movies and music can be heard with perfection and power.
How does an acoustic box work?
It works optimizing the operation of each speaker. The signal that comes to the box passes through a frequency divider circuit, a sort of electronic filter that distributes the sound properly between the various units. In audio equipment, boxes pairs are used to obtain the effect of stereophony. In theaters and home theaters, multiples boxes are used to get the surround effect.
What are Tweeters, Mid-rages and Woofer?
After the sound passes through electronic filters, it is properly divided. Tweeters are the small units of the acoustic box which are responsible for treble sounds. The units of average frequency is called Mid-Rages. And the one destinated to the serious sounds are called woofer.
What are the kinds of acoustic box?
They can be closed box, ducted box with doorway as the vented box or band pass. The closed boxes are characterized by the complete isolation of the mass of air compared to the rear boxes. It is easy to be designed but has a large internal volume of open air. It is responsible for an accurate and fast serious sound, noticed in bumbos and fast drums. The ducted boxes are also closed, except for one duct. This duct is a tube with diameter and length designed to sound at a desired frequency. It is a more complex box to be mounted. The band pass boxes are characterized by playing only one band of frequency. They are the more complicated and difficult one to hit. They have high power and are indicated for any type of music.
What is essential for the operation of an acoustic box?
The acoustic boxes need to be correctly calculated and constructed. The geometric shape can influence them in the response of frequency and yield. The walls of the box should be rigid to avoid vibrations. check the materials used in the manufacture of the box, as they should always have good levels of absorption, damping and isolation. It should be well closed to prevent leakage of air. An internal cover helps a lot, in glass wool with low density foam or polyester, to minimize internal reflections of sound.
What are the boxes of transmission line type?
They are modern boxes and different from each others. They do not look like a box because they are not closed or with ducts. They look like a cable in the rear of the box. They have a refined design and combine the low response time for a closed box with the response of a ducted box. However, its use is restricted due to its large size.
