Modern speakers now, probably, each - they connect to a personal computer, TV, laptop, they are fashionable to take with them to nature. Each of these kinds of columns has its own purpose. There are passive and active speakers, some of which are equipped with usb output, for the purpose of connecting to the corresponding connector. Let's find out what is their difference and the advantage of the latter over the former or vice versa.
What are active speakers?
Uninformed users do not even think about what columns they deal with daily. Most often these are the active columns. From passive they are distinguished by the fact that there is no need to purchase separately a special amplifier of sound, thanks to which such a column will work.
The amplifier has a small size, and it is already built into the speaker, and sometimes into each of the speakers, thereby amplifying the sound. This column is easier to connect to the media, often has usb output for work from a laptop or computer and is perfect for most cases where you need a relatively high-quality sound.
But often, the amplifier in the active column has a small power and at the ultimate load can even burn. This option is not suitable where you need a powerful sound, such as, for example, watching movies, playing games on your computer or connecting a home theater .
Passive same speakers, at first glance, have some difficulties, as they also require the purchase of an amplifier in addition. In addition, if the user does not know how to connect all these devices then you will have to look for a specialist for connection. But, they have a tangible plus - such speakers, are equipped with a powerful amplifier, and have a wonderful sound.
How to choose active floor speakers?
Acquiring speakers with a built-in amplifier / amplifiers, the user must determine their power, as well as with what quadrature they will work. Since if for a small room to buy a powerful device, it will not affect the best quality of sound, but only greatly distort it and it will not turn out to be an excellent sound.
Usually such columns are located behind the listeners and on their sides, but not directed at each other or the opposite wall, but at an angle - this should be taken into account, taking into account the situation in the room. In addition, such speakers can be single-, double-, and three-way for smoother control of sound. There are even special formulas for calculating the power of the columns relative to the size of the room.
But you should know that the floor stereosystems give a sufficiently large error of sound. Another thing - wall and ceiling active columns. They have more chances to accurately convey the sound due to their device and location. It is important only to choose the right and high-quality fasteners.
Active speakers for the computer
The main parameters for choosing computer speakers are again their power and the material of the case. To work in the office do not need a lot of power - enough will be 6W, but for home use it's better to buy a 10W column. If you plan active games and watching movies, then the speakers in 20-30 W are suitable.
The best material for the case is wood. In this frame, the dynamics will work, absorbing unnecessary fluctuations. But their price is slightly higher than plastic prices. Although the choice of design in plastic speakers is more than diverse.
To the laptop is often purchased an active column for the street with a usb connection. It is not presented with any excess demand, except for capacity. Such a column can be used in any conditions, but at home, it will also come in handy, since the speakers of the laptop itself are rather weak.
Active Speakers for TV
It is clear that the television speakers are designed for maximum quality transmission of sound. It is influenced by the sensitivity of the speakers, their power, multibandness, the type of housing. It is best for this purpose suitable columns that are located on the walls.
