When evaluating the purchase of your speakers, whether you are looking for 2.0 speakers, 2.1 speakers. sound bars, 5.1 home theater or portable speakers, you can be overwhelmed by the large number of systems available. At the same time, you will hear a large number of technical terms: tonality, realism, space, sound, etc.
Within this context, you can evaluate a measurable characteristic, which we call the frequency response of the speaker.
In this note we are going to explain what it is about, so that you can choose the speakers that you enjoy the most.
The range of audible frequencies for most humans is between approximately 20 and 20,000 hertz (Hz) during the best hearing years (before age 30). The lowest frequencies are below 35 Hz and can be felt rather than heard, like an earthquake in a movie. Sensitivity to frequencies above 15,000 Hz decreases with age in adults
When looking for, say, a home theater, aiming for good low-frequency reproduction will generally cost you more money. This is because woofers are the largest and most expensive components of a home theater or any speaker in general (also applies to 2.0 speakers, 2.1 speakers or portable speakers). Woofers take up most of the space, generally being the largest body in a home theater, and produce sounds between 40 and 2,500 Hz.
Tweeters produce the highest tones and, for example, require only a small space on the front of a 2.0 speaker. Sometimes a mid-range speaker is added to the design, to reproduce frequencies between 500 and 4,000 Hz.
To develop, for example, a 5.1 sound system, the greatest effort lies in combining the different speakers of the system with each other, aiming to generate a smoother, more precise and balanced response of all frequencies (bass, midrange and treble).
The speakers of a 5.1 sound system with good frequency response do not accentuate or diminish any part of the audible range and sound more like a live performance, being capable of producing frequencies below 40 or 50 Hz.
Subwoofers add the range necessary to feel the sound down to about 20 Hz, such as when you play the audio of a movie with your home theater where there are earthquakes and explosions. Being speakers built to reproduce the lowest frequencies, their capabilities generally range from 20 to 200 Hz.
If the frequencies drop below 20 Hz, few people are able to distinguish the sound.
Thonet & Vander's engineering and development team constantly works and researches with the aim of achieving speakers, audio systems, sound bars and home theaters that balance power, quality of materials and design. This contributes to the clear reproduction of all frequencies, especially ensuring that all our speakers offer you that characteristic clear sound and those deep bass that you love so much.
