How To Buy A New Compact Subwoofer

It is not easy for everyone to simply stroll into a store or go online and buy the best compact subwoofer. Fortunately, we have isolated a few of the most important features. These features are made in such a way that beginners can also understand them. Here is what you will need to look for in the best compact subwoofers:


The first one might seem obvious, but you will need to pay some attention to the design. Yes, we all like something modern and sleek, but oftentimes you need something that fits. The size of the subwoofer is an important thing to look for. A smaller unit might not allow you to integrate as many speakers, but it can replace some of these speakers and give you better sound.

Where You Will Use It

Not all subwoofers are the same. Aside from the size, they have a few features that can make them compatible with certain home theatre systems. Before you buy a new subwoofer, you need to determine where you are using it. Keep in mind that these subwoofers are not the ideal options for your car. You might need to make a few modifications to have them fit in your car.

Power Output

When it comes to subwoofers, you don’t need to consider the standard power output only. Most of them have a standard power output while giving you an additional number for the peak power output or RMS. It is important to consider both of these, as it could help you from burning out the capacitors with your volume or your speakers.

Bass Quality

The bass quality is probably the hardest thing to determine if you are not physically present and testing the subwoofer. However, you need to consider doing some of your research to find out more about the bass quality. One of the main reasons for buying a new subwoofer is the bass quality and it will naturally enhance your current sound.


You probably knew this feature was coming. However, it is of no use if you buy a sound system and it does not integrate with the current hardware you are using. You can look at the description to see if it might be compatible with your current system. However, most modern brands try to make their units universally compatible.


Not to scare you, but you might come across amazing deals that seem too good to be true. In such cases, you need to trust your gut, as there are many knock-offs on the market today. We recommend sticking to the brands that you know or that you have done your own research on.


A compact subwoofer is definitely a great addition to your home. If you are serious about something small that packs a lot of punch, the options mentioned above will allow you to hear a sound improvement. Let us know what your thoughts are in the comment section, and if we missed any of your favorites.
