Woofer or Subwoofer? Which one is the best?
It is essential to correctly know which product to use in your car audio, so you can have the expected result. So spending only what is necessary.
The most frequent questions when setting up a high performance and quality sound project is to know which speaker to use:
Woofer or Subwoofer?
Maybe when you came across that question and searched for “Woofer or Subwoofer?” in Google , it may have been frightened, because there are many rumors, but today we came here to simplify your life. Because each of them fits perfectly into a particular project.
So let's start with some information and difference between the two, so you can identify yourself and buy the correct one.
Using numbers, physics presents us with a translation of the sound into numbers, which is the frequency (hz).
When we have the value of 1 (hz) it means that it is a very low sound, already at a frequency of 15,000 (hz), it is a high-pitched sound. These values determine the length of wave sound, resulting in motion a loudspeaker have to do to convert the numbers into sound.
Explaining now in practice:
Bass and medium bass speakers are called Woofers. And they work in the frequency range from 50Hz to 4500Hz (approximate). The subwoofer and bass speakers are called SubWoofers. And work in the frequency range from 20Hz to 200Hz (approximate)
These are the differences represented in frequency (very important when configuring the module)
Due to the large market, a woofer can be confused with a subwoofer, only in the matter of nomenclature, where 15 and 18 inch woofers are also called subwoofer.
To better understand this, let's go to the examples:
A loudspeaker that has a high rubber or foam rim, are manufactured for internal sound, known as subwoofers. Look here for additional insights: 2 way vs 3 way speakers
Loudspeakers that have a wavy edge that resembles paper, are manufactured for external sound.
And now, woofer or subwoofer?
These are not the main differences:
Finally now after knowledge. We know that if the sound project is for outdoor areas such as parties, barbecues, farms and etc. It is recommended that you use a speaker that plays at a higher frequency, sending the sound further away.
Now if the project is a more serious sound, which gives a full-bodied music, being for indoor areas, more focused on cars, where it is a small environment. So it is recommended that you use Subwoofers speakers.
Frequency table (summarized):
· 1hz: it means a movement of the cone (back and forth) in one second, it is inaudible.
· 10hz: means 10 round-trip movements of the cone in one second, just wind.
· 25hz: More wind than sound. Mechanical movement, the environment trembles.
· 40hz: You will start listening to the sub-bass, in addition to feeling everything vibrating. Very extensive sub-bass.
· 50hz to 60hz: Sub-bass with more pressure, strong bass but very extensive.
· 70hz to 100hz: Little sub-serious. Feeling of more pressure, vibration.
· 100hz to 150hz: A lot of vibration, very firm bass, very strong, it hurts the ears.
· 150Hz to 250Hz: Very fast vibration. Here the rubber-suspension speakers will yield almost nothing.
· 250Hz to 500Hz: A lot of vibration. Fuller voice and very fast, dry beats.
· 500hz to 1000hz: Pure voice, full-bodied voice, as well as various instruments, alarms, horns, etc.
· 1000hz to 3000hz: Voice with little treble, screaming voice, horns and alarms higher, other instruments and sounds that cause discomfort to our ears.
· 2000z: This is the resonance frequency of most humans. It is an irritating frequency to the ears. We recommend lowering this frequency by 2 to 3 dB, if you have an equalizer, so the sound of the drivers will be much more pleasant.
· 3000hz to 5000hz: High-pitched voice, very fine and strong high-pitched voices, well-defined, hissing, violin sounds, keyboards, last guitar notes, pounding metal sounds, etc.
· 5000hz to 20.000hz: Pure treble, the higher the frequency, the finer and weaker the treble, that is, at 5000hz you hear a stronger treble, but above 10,000hz it is already very weak.
