How to connect a subwoofer? Councils and recommendations.

To date, the standard sound, installed on various audio systems, many do not like. In order to change this opinion, manufacturers are releasing additional equipment, connecting which one can achieve the desired sound quality.

The subwoofer is included with any standard home theater system, it is necessary for reproduction of low-frequency sound special effects. Connecting a subwoofer will ensure that the sound is as close as possible to the actual spectrum.

How to connect an active subwoofer ?

There are active and passive subwoofers. Active devices feature a built-in amplifier that allows you to remove the load from the main amplifier located in the home theater. This model requires a separate connection to the electrical network. The advantages of this type of device include the ability to control the separation frequencies. This makes it easier to reconcile the various components of the main system. The main disadvantage is the relatively high cost.

How to connect a passive type subwoofer ?

This model of the device is connected to an external amplifier. A number of disadvantages of such devices cause their relatively low cost. Connecting a subwoofer of this type implies the need for it to be accurately linked to the speaker system that is available. This process is rather complicated in implementation. Connecting via a separate power amplifier, as well as an electronic separation filter, will significantly reduce the distortion of the nonlinear type. This is achieved by dividing the signal according to a special scheme. Thus, it is possible to release the main amplifier from increased loads.

What should I do before I connect the subwoofer?

In order to achieve the best results, it is necessary to take into account the size of the room where the system will be installed. Also very important factor is the dimensions of the device. This is due to the fact that partially nonlinear distortions of sound vibrations depend on the dimensions of the model case. Compact models are not capable of reproducing fully low-frequency sounds. Therefore, you should choose those models that optimally fit into the interior of the room. At the same time, the power characteristics of the device should be calculated in such a way that they exceed the analogous parameters of the acoustic system by at least one and a half times. The most suitable option for a home system is a bass reflex or closed subwoofer. The power of such a device should be within 150 W, and the range of reproduced frequencies within 30 - 180 Hz.

So, a home subwoofer is the right purchase, which will allow you to fully enjoy the real sound when watching a good movie at home. But to observe all the necessary subtleties in the process of connection is very difficult. Therefore, when buying a device, it is better to resort to the help of a specialist. He will advise how to connect the subwoofer in the best possible way. After all, with today's wide choice of such technology to choose a device that has the necessary characteristics, design and acceptable dimensions is not easy. Such a specialist is able to better meet your requirements based on the knowledge of the pros and cons of the various models on the market.

In the modern world, there are expensive models that are capable of reproducing sound within 25 Hz. The acquisition of such subwoofers is not always justified, since the ear of a person is not able to hear in this range. Proceeding from this, you should not overpay and buy a device that you can not evaluate.
