Buyer’s Guide

If you are trying to find the best sound quality subwoofer, the choice isn’t that complicated than it may seem at first. All you need to do is to check your specifications and find the solution to satisfy your objectives. Without defining what your system really needs, a lot of newcomers make the same typical mistake — they just give their preference to the most liked or advertized solution.

Of course, this approach may work. Reputable brands pay a lot of attention and efforts to ensure the excellent quality of their production. However, don’t forget about the variety of quality tools available on the market. In order to make a beneficial purchase, feel free to consider the following tips and recommendations.

Accuracy in Frequency Response

One of the main things in subwoofers is the way they represent bass sounds, their clarity and distortion. The best solutions are very accurate in performance, and the range of available frequencies is the biggest one at low frequencies. In this case, it doesn’t even matter if you can’t hear the lowest tones — you will definitely feel them!

It is also a good thing to pay attention to the amount of energy necessary to create this or that melody.

Space Restrictions

Apart from checking how suitable the solution will be for your budget needs, you have to verify it is a matching one for your vehicle. If you would like to stay on the safe side, go for smaller options. However, don’t forget to see whether the present frequency response and RMS power rating are worth the game.

Subwoofer Size

For those customers who are looking for solutions for their cars, it is not necessary to select the biggest options. Ten- or twelve-inch solutions are good to start with. Please consider the next fact as well: the amount of energy to put out depends on the size of the driver. In turn, the bigger the latter element is, the more powerful sound you will achieve at the end.


What is the difference between SQ and SPL?

In simple terms, Sound Quality is used to describe those tools which can show off with their fidelity and clarity of performance. At the same time, the accuracy of each frequency to hear is excellent. The opposite notion, i.e. Sound Pressure Levels, refers to how loud the sound representation of this or that model can be. It is measured in decibels.

What Hertz rate is the best one for bass?

There is a simple rule of thumb to bear in mind: the lower the Hertz available in the model is, the more bass it is possible to get. In this case, a range from twenty to one hundred twenty Hertz is the right shot. Still, bigger ranges will help you enjoy more sound tones.

What is the best RMS rate for a SQ subwoofer?

Of course, a lot depends on your car audio system and whether you have other equipment to link a sub with. In general, the minimum power to look for is two hundred fifty watts RMS. If a solution is capable of delivering around five hundred watts RMS, it is a true powerhouse. More powerful solutions aren’t that requested for limited space of cars and other vehicles.


The choice of the best sound quality subwoofer for your needs should be nothing but exciting and pleasant. Check out the list of premium recommendations and tips for beginners to make the right selection. Enjoy the deep bass you deserve!
