How to Choose 18-Inch Subwoofers
Here are the top features to consider when choosing the best 18-inch subwoofer for your needs:
Speakers Size:
Subwoofers come in many different sizes, but if you are looking for a really big bass sound, then you should choose a larger 12-inch or 15-inch speaker. A 12-inch subwoofer is on the smaller size while 15-inch is on the bigger side of things, but it doesn’t mean that all 15-inch subs produce equally loud sounds. You can choose a 12-inch or 15-inch speaker depending on your specific needs.
Power Handling:
The most powerful subs usually have a power handling range of 300 watts to 800 watts. However, if you want something more luxurious then look for subs with a power handling range of over 1,000 watts. The lower end subs offer decent quality sound but also at decent prices while the high end subs can produce sounds louder than cars speeding past your front door at 80 mph+.
Materials:
It is important to look at all of the materials used in the subwoofer because each material has its own notable characteristics.
A sub can be constructed of various metals, plastics, composites, and others that will either affect the sub’s durability or the audio quality output. If you are looking for a sub that will last longer then you should definitely choose one that has a metal construction.
