What makes a good subwoofer?
Choosing the best subwoofer for your needs can be a difficult task. There are many factors that need to be taken into account when making this decision. The most important factor is the size of the speaker and how much power it can handle.
There are two types of subwoofers: passive and powered. Passive speakers require an amplifier to work, while powered ones have their own built-in amplifier. If you want to save money, go with passive speakers; if you want more features, go with powered ones.
There are a few elements that are essential in the best subwoofers:
- No Distortion – When you crank your speakers, you don’t want them to make a nasty distorted sound. Cheaper subwoofers tend to be more prone to distortion than more expensive ones.
- Clear, powerful bass – This really goes without saying, but the most important element of subwoofers is a great bass! This is their job. You want to make sure they can handle the lowest sub frequencies with ease.
- Loud volume – Having subwoofers that can output a large amount of volume is the best way forward. This way, you are assured that the subs fill the listening space with bass.
- Good wattage handling – The more wattage, the more power and thus louder a set of speakers can be. If you have low-wattage subwoofers, they won’t be able to create such a loud sound.

How to choose the best subwoofer for your needs
There are many factors that you must take into account when choosing a subwoofer. The frequency, size, and power of the subwoofer will all have an impact on your listening experience.
The frequency or the range of sound that this subwoofer can produce is important to consider. You may want a subwoofer that can produce low frequencies or one that focuses on high frequencies.
The size of the enclosure is also important to consider because it can affect how much bass you hear. If you want more bass then you should choose a larger enclosure but if you want less bass then you should choose a smaller one.
A larger enclosure will be louder than a smaller one but it will also have more distortion and less accuracy in sound reproduction than a smaller one.

FAQs
What subwoofer has the deepest bass?
A subwoofer is a speaker that is designed to reproduce low-frequency sound. It is typically used in conjunction with a full-range speaker system.
A subwoofer has the deepest bass when it can produce the lowest pitches or frequencies. The frequency response of a subwoofer is measured in hertz and ranges from about 20 Hz to about 200 Hz. On this list, the AudioPipe TXX-BDC4-15D2 has the lowest bass handling.
Are 15-inch subs louder than 12?
We are all familiar with the age-old debate of 15-inch subs being louder than 12-inch subs. But, is this true?
The answer is yes and no. It all depends on the type of subwoofer you are using. A 15-inch subwoofer will be louder than a 12-inch subwoofer if it has more power output. However, if the two subs have similar power output, then the 12-inch subwoofer will be louder because it has a larger cone surface area which produces more sound waves than its smaller counterpart.
What are the hardest-hitting subs on the market?
The Gravity Warzone range is super hard-hitting. I recommend these if you want max bass and volume.
Are 15-inch subs good?
The answer to the question is yes, 15-inch subwoofer speakers are good!
A 15″ subwoofer speaker is a great choice for people who want a powerful sound but don't want to spend too much money. This size is also perfect for people who have limited space in their car or home.
