2ohm Or 4ohm Subwoofer?Which is The Best Subwoofer?
Every time people talk about the subwoofers, they usually come across the term ohm which is symbolized as Ω. But most people do not understand its meaning. It is important to understand and know why you have to have 2 ohms or the 4 ohm subwoofers.
Depending on the quality, the different subwoofers will always consist of recognizable difference regarding durability as well as loudness since they have a different impedance which is the resistance provided by an electric circuit of the alternating current (A/C).
When compared with price, the brand will always be a great factor. In most cases, the 2 ohms is a bit expensive than the 4 ohms.
The 2-ohm Subwoofers
When looking at the ohm (which is the international system of a unit of the electrical resistance) when choosing subwoofers, it mainly determines how power the subwoofer can hold as well as transform to sound.
The subwoofers with lower electrical resistance tend to produce louder sound compared to the high electrical resistance. Hence, the two ohms subwoofers are louder than the 4 ohms subwoofers.
However, the 2 ohms subwoofers may be louder than the subwoofers with more higher resistance; it is may also produce a low quality of sound because of its power consumption. Regarding the size and brand of the subwoofer, a 2 ohms subwoofer’s price ranges from fifty dollars to two hundred dollars.
The 4-ohm Subwoofers
The 4 ohms subwoofers have a higher electrical resistance. They tend to produce minimal sound compared to the 2 ohms subwoofers. However, the 4 ohms consumes less power; hence, they tend to last longer than the subwoofers with the lower resistance.
The 4 ohms subwoofers produce a more compact sound which may mean a great quality sound compared to the 2 ohms woofers. Regarding the size and brand of the subwoofer, a 4 ohms subwoofer’s price ranges from twenty dollars to one hundred and eighty dollars.
2-ohm Subwoofers Vs 4-ohm Subwoofers
Most people may not know the difference between the 2 ohms and the 4 ohms subwoofers. Generally, they have just a few differences. Their differences lie on how much resistance each has, how much power they consume, and how much dB they can produce.
A dB is a logarithmic unit that measures acoustics. However, the important thing you should always note is that, it is recommended you connect a subwoofer to its corresponding amplifier which has the same resistance.
To clearly understand this, let us say that you have two subwoofers, 4 ohms, and 2 ohms subwoofers. Having your 2 ohms subwoofer at the 2.83 watts, it produces 93 dB while the 4 ohms subwoofer will have 90.5 dB at the same wattage.
The two subwoofers tend to have a difference of 2.5 dB, which is very noticeable if you are very keen on audio. But if you are not keen, you cannot recognize the difference.
Regarding the sensitivity, that is the quality of the sound produced by a particular subwoofer, let us assume that the 2 ohms subwoofer is at 86.4 dB at one watt, then the 4 ohms subwoofer will have 86.6 dB at the same wattage.
The two subwoofers will have a difference of 0.2 dB which is a very small difference. In the real sense, the 4 ohms subwoofer technically produces a high-quality sound compared to the 2 ohms subwoofer. However, the is so small to be noticed.
Hence, in simple words, the difference is very small. If you are planning to buy some subwoofers, you can buy the 2 ohms or the 4 ohms since they will produce almost the same sound quality if run in the same wattage. The sound produced by the two subwoofers will have very little difference, the main difference in the two subwoofers will be their prices.
Why Most People Choose The 4ohm Subwoofer
The 4ohm subwoofer produces a softer sound as compared to the 2ohm subwoofer that produces louder sound having the same wattage. A softer sound sounds better in our ears than a louder sound.
Most individuals always pick the 4ohms subwoofers since they tend to produce a bit better sound quality than the 2ohm subwoofers that produces a bit poorer sound quality. However, the difference is slightly small, but always choose the best.
Also, regarding their price, the 4ohm is a bit cheaper as compared to the 2ohm subwoofers. However, the price may also depend on the brand of a particular subwoofer. The 2ohm subwoofer ranges from $50 to $200, while the 4ohm subwoofers range from $20 to $180.
The other reason as to why most people consider buying the 4ohm subwoofer is that it has higher electrical resistance while the 2ohm subwoofer has a lower electrical resistance. However, you should always connect your 4ohm subwoofer to its corresponding amplifier.
If you are not one of the audiophiles, you can pick either the 2ohm or the 4ohm subwoofer. Generally, the two subwoofers have slight differences which the non-audiophile cannot notice. Hence, do not let the slight difference be a break or make when searching for your sound system components.
The two subwoofers are just almost the same but with very little different impedances. The two subwoofers can produce almost the same sound quality if they run at the same wattage. The difference in the quality of the sound is very small to be noticed.
