Subwoofer Buying Guide

Next stop will be your guide in choosing your subwoofer. These are the things that need deep consideration in your part. Subwoofers are built not only for better audio output, but to also give you that positive entertainment while you travel.

You will not be only making benefit out of it in your travel, but also when you and your family decided to go for an outing. This will be also very useful when that time comes.

Subwoofer size

When it comes to subwoofers, size matters. The typical subwoofer size ranges from 8, 10, and 12 inches. If you have ample space in your car, then a 12-inch subwoofer may be the best option for you, as it can provide a powerful and satisfying sound output. On the other hand, if you have limited space and want to maximize your cargo room, then an 8-inch subwoofer may be a better fit.

An 8-inch model can still provide deep, forceful, and satisfying sound, but for those looking for maximum bass impact, a larger subwoofer will be the way to go. When considering the size of a subwoofer, it’s important to consider not just the physical space available in your car, but also the desired performance level. Larger cones can produce deeper bass and more space for air movement, but it ultimately comes down to the space you have available.


The subwoofers do a lot of job by generating lots of power to generate huge bass. The sound waves produced by the bass are very big. These kind of bass can only be handled by an external amplifier. Just simply put the more power you have the better.

Imagine a truck with V-8 engine travelling through an incline stiff, sure it can run smoothly, but imagine if the truck has 3-cylinder motor, then most likely it will struggle travelling through. The same idea goes in choosing the amp to power up your subwoofer.

There are two things you need to consider before buying your amp. The first one is the subwoofer’s upper RMS power-handling spec, and the amp’s RMS output. RMS refers to amount of power the speaker could handle while you play your music.

The ideal amp’s RMS output wattage is ranging from 75% to 150%. This increases the power of subwoofer to handle the heavy bass. In choosing the best power handling, don’t forget the simple idea of: The more power, the better and safer sound production.

Low-pass filters

Low-pass filters are a crucial component of subwoofers, as they allow only low frequencies to pass through and block high frequencies. This helps to ensure a clear and quality music production, as high notes can detract from the overall sound. A good starting point is to set your low-pass filter to 80 Hz, and then adjust it lower if the sound is not to your liking.

Many modern subwoofers come equipped with low-pass filters, making it easier for drivers to achieve the desired sound output. Experimentation may be necessary to find the right balance, but the end result of having a reliable and satisfying musical experience while on the road is worth the effort. It’s important to note that setting the low-pass filter too high or too low can result in overlapping or gaps in the music, so it’s best to aim for an average measurement.


A proper amount of impedance is important so that you’ll have a stable and a safe way of using your subwoofer. Take this for an example, if you have a subwoofer that 2 ohms, then you have to check if your amp is 2 ohm stable. The resistance is very important, since it regulates the power travelling to the circuit.

The impedance that is very low will result for the amp to overheat for delivering a power that it can’t handle. Just like said, it is important that there should be a careful balance of the in and out of power in the system.

Enclosure type

Every subwoofer needs a box, or what we call the enclosure. In order for your subwoofer to perform it needs a type of enclosure. This will define a lot of what kind of music is produced out of your chosen type of enclosure. To make it short, the bass production you get will highly differ on the enclosure type.

Now, there are two types of enclosure. The first one is sealed and the second one is ported. The difference between the two? Well, put it simply as it is. The sealed box are airtight, meaning the sound will be tight, accurate, and loud.

Ported box has the feature a tube or a vent to allow the air to pass in and out of the box. It creates a sound production of both loud, deep, and booming. Just imagine a guitar, it won’t make a sound unless there is a proper type of enclosure.
