Factors to Consider Before Buying
Buying a subwoofer when there are so many types in the market definitely is confusing. In order to get the best 
15-inch subwoofer, there are important aspects you should focus on.
Power
Power is the most important aspect to be looked into when buying the best 15-inch subwoofer. For a music system, lesser power means lesser fun. Hence, always look for higher power levels.
There are two types of power handling: RMS power and Peak power. The RMS power rating indicates continuous power output. It is powerful than peak power. Thus, subwoofers with RMS power of 800 or more will make a great buy.
Sensitivity
Sensitivity goes together with the power so as to achieve high output. It is measured in decibels. A subwoofer with a higher sensitivity rating needs less power to offer same amount of sound when compared to one with a lower sensitivity rating.
Frequency
The main purpose of frequency is to catch the lowest and highest range of sound, but with perfection and accuracy. A higher range is more capable of attracting the correct sound. Meanwhile, low range frequency subwoofers ensure you enjoy the low bass notes to the fullest.
Voice Coils
There is variation between different subwoofers when it comes to coils. More than two voice coils can be included in a speaker. However, dual voice coils subwoofers is a good choice for car audio enthusiasts.
These utilize two separate voice coils: Each of them has a separate connection, mounted on one cylinder and connected to one cone.
Enclosure
The area in which the subwoofer is packed affects sound quality. Subwoofers are normally packed in a box. Sealed boxes produce the most accurate and deep sounds. However, if you are searching for more volume, the ported and bandpass enclosure types are the best choices for you.
Nominal Impedance (Ohms)
This is the measure of resistance within the flow of alternating current. Sound systems with fewer Ohms are more effective as there is less resistance. Impedance may be optimized for subwoofers with dual voice coils.
Control
It would be a loss if you acquire a subwoofer without comprehending its controlling. Some of them come with a remote while others do not. If you want one that is easy to control, ensure you get a model that comes with a remote.
Integration
If you have a modified sound system before buying a subwoofer, it is important to know whether the subwoofer you buy will suit your system or not. Buying an expensive model does not necessarily mean that it is capable of supporting and performing well while working with other parts.
Crossover
This is the circuit that prevents the entire sound system from receiving a wrong frequency. As you know, a sound system has various parts and all of them have different functions and different frequency-receiving abilities. Thus, the crossover makes sure all parts receive the required frequency.
Custom Sound
Subwoofers that feature pre-set modes are the best as they are capable of customizing the subwoofer’s bass response depending on the type of music you are listening to. Moreover, the high-end models feature a built-in microphone that takes the sound sample and adjusts the sound to suit your space.
Are you looking for a full, quality sound for your vehicle audio system? Consider adding the best under seat subwoofers. It will give you some of the basses that’s been missing. They’re designed for smaller, enclosed spaces.
Front-Facing Versus Down-Facing
A front-facing subwoofer has a speaker that is placed in such a way that its sound radiates from the front or side of the subwoofer enclosure. The down-facing subwoofer, on the other hand, has a speaker that radiates its bass downwards. None is better than the other. Your choice depends on your preferred style.
Available Space
Before you buy a given model, you should first ensure that it will fit in your car. This depends on the volume of the enclosure in which it is housed and how big your car is. Most manufacturers specify configuration and volume of the box that should be used in housing their subwoofers.
