The sound towers have become one of the best christmas gifts For friends, brothers, parents or boyfriends in love with music or movies, a very practical solution to improve the sound system in any house.
Listen to a music record or watch a movie with some column speakers drastically improves the experience compared to the speaker built into the television. Although there are different classes, the sound towers they are generally the best speakers for listening to music.
The height of these sound columns allows the integration of large cones that offer a sound that is much more faithful to reality, reaching an almost always greater frequency range.
Bluetooth speakers, buying advice to choose the best one
One of the things you should know before buying a sound tower is that in the world of audio, quality generally comes at a price. Just as €700 headphones do not sound the same as the ones they give you on the train, a 50-euro sound column is not the same as another that can be worth more than triple the money.
As always, the ideal is to try before you buy, much better if you can do it with music that you play regularly to capture all the nuances. Below you can review some shopping tips and tricks What you should know before choosing one column or sound tower:
If you plan to put one sound tower In the living room of your house, the first thing you should think about is the place it will occupy, thinking carefully about whether you have enough space for the sound to breathe.
The best place to place a speaker or sound tower depends on each house, but it is essential to place it in a space where there are no objects in its path that could generate annoying distortions. Although it is common, it does not seem advisable to install a sound tower in the corner of a room.
If you are going to place two sound towers, one on each side of the television, you must place them with an identical separation to generate a perfect sound in the room, although you must know that it will not be heard the same in one place as in another, something that usually people tend to overlook.
Greater frequency range does not imply better sound and neither does the opposite. The human ear, which has evolved over the years, is capable of hearing sound waves at frequencies ranging from 18 to 20,000 Hz.
Bass sounds correspond to low frequencies, ranging from 16 Hz to 256 Hz; the means are in the frequencies that go from 256 Hz to 2,000 Hz; and, finally, the high-pitched sounds are between 2,000 and 20,000 Hz.
The spectrum of many commercially available speakers and sound towers starts at 45 Hz, relying on an external subwoofer to reproduce the lower frequencies. However, it seems much more advisable to select a speaker capable of reproducing all frequencies on its own.
More speakers don’t have to mean better sound. First of all, you should know that to listen to the usual television channels (DTT) and some music, a 2.1 system is enough, but moviegoers and audiophiles will appreciate the 5.1 surround sound.
What is the difference between 5.1 and 7.1 sound? Generally scant. The vast majority of movies are sold with 5.1 sound, so when listening to them with a superior system, the sound will somehow distort the original band.
In addition, it is difficult to install a 7.1 system properly if the room is not excessively large, so for most it seems more advisable to buy a good 5.1 system.
Speaker and driver size
You probably know that small speakers play high-pitched sounds very well but have trouble with bass, while large speakers often have trouble playing high-pitched sounds.
Drivers or electromagnetic transducers are responsible for transforming energy into sound waves. There are different types of drivers: woofers for bass sounds, mid driver for midrange, and tweeter for higher-pitched sounds.
Most modern speakers are two-way, that is, they incorporate two drivers -usually a tweeter and a woofer- to reproduce the sound more faithfully. You can also find 3-way speakers in stores that have a transducer for the midrange, but that doesn’t automatically mean they sound better.
at the time of buy a sound towerHowever, it is much more advisable to choose a speaker with drivers or cones that are larger than 6.5 inches, since smaller ones will have a more difficult time representing sounds of all frequencies.
One of the fundamental characteristics of a sound tower is the ability to connect to all kinds of devices. If you are going to connect it to the television, it is best to use cables, but you will probably be interested in incorporating wireless connectivity through WiFi, NFC or Bluetooth.
Bluetooth is the universal system par excellence but it compresses the original audio signal, which means a reduction in the final sound quality.
The default codec (SBC) in A2DP profiles offers quite mediocre results, so it is always advisable to choose equipment -both transmitters and receivers- that incorporate the APTX codec when sending music via Bluetooth, which considerably minimizes losses when transmitting the signal .
In any case, it is more advisable to use other wireless systems to send music such as AirPlay (Apple), AllShare (Samsung), NFC or similar.
Some extras may be more interesting than others when it comes to buy a sound towerAlthough it all depends on the tastes of the user. FM radio is usually one of the most requested features, but interference spoils the sound quality.
The touch panel is a very comfortable element when playing music, while for many the essential element of any sound column is a mobile dock port, always with the greatest possible device compatibility.
More power is by no means equal to better sound, but in many cases the increase in power is accompanied by distortion of the bass and treble.
Unless you are going to use the column speaker in a very large room, a power of 100W per channel will be much more than enough, unless you want your neighbors to stop greeting you on the landing.
When comparing sound towers it is essential to look at the average power (RMS) which much better represents the differences in volume between the speakers. For a normal room, an RMS power of 60W is more than enough.
The impedance reflects the resistance to alternating current. The higher the impedance, the more power is required to reproduce the audio at the same volume, while the lower the impedance, the sound will be “cleaner”.
If a speaker has an impedance with respect to the sound emitting device, absolutely nothing will be heard, something that is impossible in high-quality audio equipment, since a good speaker or a good sound tower can have, for example, an impedance of 10 Ohm. .
