Active TV speakers: features of choice

Now almost everyone has a stereo system at home for a TV, computer or laptop. But when buying a TV, we pay more attention to image quality. We think about sound later when the TV is already installed. Here the question arises - which speaker system is better to choose? Speakers are also different, for example, active or passive. Let's try to figure out what is the difference between them and which are better.

What are active speakers

Many ordinary users do not even think which columns they use. In most cases, these have been active speakers lately.

The difference between active and passive speakers in the presence and absence of an amplifier. For the former, it is already integrated, and for the latter, you will have to purchase the device separately.

The active speakers for the TV already have a small amplifier. Sometimes, it is installed in the speaker itself. Such speakers are much easier to connect - you don’t need to pull a lot of wires and most often they have a USB cable that connects easily to both the computer and the TV. Active speakers will quite cope with the task of reproducing more or less high-quality sound.

This device also has disadvantages. They are hardly suitable for reproducing loud and powerful sound. Under heavy loads, the built-in amplifier can simply burn out. For example, if you often watch movies or play the load will be too much. They are also not suitable for connecting a home theater.

Passive speakers

A device without a built-in amplifier is, at first glance, less convenient. For quality work, you need to purchase an amplifier separately and connect it. In addition, in order to connect all this correctly, you need to understand at least a little bit about the topic, spend a lot of time reading the instructions or invite a specialist.

Of the advantages of such speakers can be identified resistance to stress and sound quality.

How to make the choice of active speakers

When choosing speakers with a built-in amplifier, you should calculate their power and the quadrature for which they are intended. It would seem that the more powerful, the better? No. If you install a stereo system designed for 30 square meters in a small room with an area of ​​16 square meters, you will get nothing but sound distortion. That is, you need to choose the columns for the available area.

But you should also consider the situation in the room. Column placement also plays a role in sound quality. The devices are placed at an angle, that is, not to each other and not to the wall opposite, but to the center of the room or the seats of the audience.

Active devices can be two-, three, and single-lane. This characteristic affects the smoothness of the sound control.

To calculate the power needed for a certain area, special formulas are used. Although these indicators are now most often indicated on the packages.

Stereo systems for the TV can be floor, wall and ceiling. The former are at greater risk of sound distortion. The rest, due to their structure and arrangement, reproduces a cleaner and more accurate sound. For the latter, it is very important to choose high-quality and suitable fasteners so that they do not fall on someone’s head from vibration.

If we are talking about active speakers for a TV, then wall-mounted devices will best cope with the task. Factors such as:

• sensitivity;
• power;
• polyphony;
• type of shell.

A simple solution

In order not to torment yourself with calculations and the selection of system parts separately, you can pay attention to ready-made speaker systems designed specifically for TVs. Usually they already include:

• 5-7 columns;
• sound amplifier for TV;
• subwoofer
• connecting wires.

In such kits, everything is already selected. It is only necessary to select some individual parameters.

Sensitivity

This characteristic is responsible for the sound volume - the higher the sensitivity, the louder the sound. Devices in which this indicator is high do not require an additional amplifier. You can see the sensitivity level in the characteristics of the equipment.

Here, low sensitivity is indicated as 84 - 88 dB, and high - 94 - 102 dB.

Power

For your speaker system to serve faithfully for many years, you need to pay attention to the power indicator. The amplifier should be weaker than the speakers or on an equal footing, otherwise the latter will simply burn out. For example, for a room of 17 square meters, 80 watts will be sufficient.

Body

There are two types of enclosures - closed and bass reflex. The latter is considered the most popular. A phase inverter is an opening on the front or rear wall of the housing that connects the internal volume of the column to the external volume of the room. This solution significantly lowers the level of cutoff frequency and increases the sound pressure level at low frequencies.

The closed case is the simplest. It is a sealed box. It has high transient characteristics, from the disadvantages - it is difficult to get a low cutoff frequency.

A bit of specificity

The cumbersome home theaters were replaced by sound bars. If you want to maximize the potential of the speaker system, you should pay attention to the HTL9100 from Philips and similar ones. There is a sound bar and subwoofer that provide great sound. In addition, the model looks very stylish and will fit into any interior. Such pleasure will cost about 15-17 thousand rubles.

Among the TV stands, there is also something to choose from. So, HTL5120 of the same manufacturer and the like. The system processes low-frequency sounds quite qualitatively, and is great for watching movies. It is this device that costs about 5,000 rubles.

For music lovers, Roth Oli audio systems are recommended. The manufacturer has recommended its products of high quality and reliable.

In the end

The statement that the sound quality is erroneous depends on the size of the speakers. It depends on the speakers, and their high quality can easily fit in a small case. So pay attention to specifications, not size. Of course, if you do not want to overpay for plastic.
