If you’ve been on the lookout for the best 15-inch subwoofer, you’ve hit the jackpot. We will take you through a comprehensive review and how to buy the best subwoofer in this post.

What features to look for while buying a best 15 inch subwoofer?

 This size of the subwoofer is a favorite of many car owners due to their compact and standard size. However, the perfect size alone does not define a great subwoofer. Here are the features that you should consider while buying a 15-inch sub.

  1. Enclosures

Irrespective of the size and power, the placement of the subwoofer has a significant impact on the sound quality. The first thing you want to make sure is that it fits comfortably in the boot of your car. The next thing is to consider what type of enclosures you prefer.

Currently, there are two types of enclosures for subwoofers – enclosed units or boxes and universal boxes.

Enclosed boxes are either tailor-made for a specific car or have a rectangular/square design. They have a higher price tag than the other category.

Universal boxes are built without power or drivers. This makes them have a low cost. But the catch is, the user is responsible for assembling it and connecting it to the power source.

The custom-built boxes are also in the category of universal boxes. They are unique in that they are custom-built to fit a specific car and its user. They are among the premium priced subwoofers.

  1. Configuration of the box.

Typically, there are three ways in which these boxes are configured;

  • Sealed – These boxes produce crisp, clear sound with the power of the bass being secondary.
  • Ported or vented – These boxes produce a vibrational sound filled with heart-pumping bass.
  • Bandpass – It is the perfect balance between powerful bass and crystal clear sound.

Alternatively, there is a cheaper subwoofer without a box enclosure called the free-air configuration. The overall sound is a substandard quality, but they are easy to handle.

  1. Power.

This is perhaps the most vital feature that will determine the performance of the speaker. The most important thing to consider about the power of the subwoofer is the RMS or root mean square. The next thing you want is to make sure the amp’s output and the woofer’s handling are compatible.

  1. Active vs passive subwoofer.

Active subwoofers, also known as pre-powered subs have built-in amplifier and receiver. These are an excellent option if you are low on space but do not want to compromise the quality of the sound.

Passive subwoofers use external amplifiers. They are best for custom installations such as a home theatre.

  1. Frequency

The range of the frequency is the range of sounds that can be produced by the subwoofer. The lower the frequency, the better the sound. Frequencies lower than 250 Hz is most ideal for a 15-inch subwoofer.

  1. Sensitivity

The sensitivity determines the power required by the woofer to produce the best sound. The ones with higher sensitivity can work without using a lot of power. The sensitivity of a sub is measured in decibels. 

  1. Voice Coils.

A subwoofer with dual voice coil has more flexibility than those with the single voice coil.

  1. Impedance

This is the electrical resistance measurement of the subwoofer. They are most commonly measured in ohms with 4 ohms being the most common. It is important to make sure that the subwoofer and the amplifier match both in impedance as well as power rating.

  1. The type of music you play.

Although this is not a feature of the subwoofer per se, it also affects how the sound is produced. 15-inch subwoofers produce the best sound while playing hip-hop, rap, and R&B genre.
