Get Familiar with the Sound Terms

If you are not familiar with any of the terms located in this page, do not worry, we will explain everything you should know before doing the right purchase for yourself. Below you will find the terms of sensitivity, frequency range, RMS, Peak power handling figures.

Design of Speakers, 2-Way vs 3-Way vs 4-Way

Speakers have different drivers that produces different sound waves. At very least a speaker with 2-way will have a woofer and a tweeter. Woofers are bigger drivers that are aimed to produce bass sound and operate at low frequencies. Tweeters are smaller drivers which operate at mid - high frequencies.

If a speaker has 3-way, this means it has a mid-range driver which makes a gradualy frequency distribution between woofer and tweeter. You may see a 4-way speaker, this time it will have a supertweeter for reproducing only high frequency sounds.

Increasing number of ways will not add any speaker a subwoofer. Subwoofers have bigger cones starting from 8" sized to whatever you can imagine. They operate at low frequencies such as 20-100. 

Increasing number of way in same series or brand, will indicate a richer sound quality. However if you want to compare between brands, you will most probably get to nowhere. Most of the elite speakers are only 2-way and they have better sound quality than cheap 3-way, 4-way speakers. 

For more detailed information about on this subject, please visit our guide that explains what is 2 way car speaker means.

What is the Difference between Component vs Coaxial?

There are two speaker types according to their build. Component speakers have each drivers are placed on their own as you would see in a home theatre speaker. For example a 2-way component speaker may have a woofer placed in the car door and the tweeter placed on the corner of dash.

Coaxial speaker have all of their drivers placed on woofers. Tweeter, mid-range and if there is supertweeter are all placed on top of woofers and do not hold extra space on your vehicle.

Some people claims that compenent speakers are way better sounding compared to coaxials. We do not agree with that. Component vs coaxial choice is more related with aestatics, not performance.

What is RMS and Peak Handling Values?

RMS is the power handling value of a speaker continuously. You will not damage your speakers by tuning your speaker up to this power level.

Peak handling value is the maximum power input that a speaker can handle without failing. You should be staying away from this value.

As a stock, if your car does not have an amplifier, your speakers get their power directly from the head unit. They can power speakers up to 50 watts. If you are going to buy a speaker that has an RMS level around 50 watts, you do not necessarily need to buy an amplifier.

If you want to get more volume from your speakers, you can overpower your speaker up to 1.5 times of RMS level. Still, for a longer life span for your speaker, we do not recommend that.

What is the Sensitivity Level?

The sensitivity level indicates the sound intensity in terms of dB when you power a speaker by 1 watt and measure from 1 meter away. Higher sensitivity means you can get higher volume although you power them at the same rate.

What makes it's important? Well, there is a limit to how much you can power your speaker. If you want to increase the volume of your speaker by 3 dB, you need to increase the power input level by double. For example, if you have a 90 dB sensitivity level speaker;

  • At 2 watts - 93 dB,
  • At 4 watts - 96 dB,
  • At 8 watts - 99 dB
  • At 32 watts - 105 dB

you will obtain it from. Frankly, 90 dB sensitivity is an indication fo good speaker and if a speaker can reach 105 dB at RMS power level, it should satisfy you.
