Best SPL Subwoofer Buying Guide

Do you want to buy the best SPL subwoofer for your car? It can be a difficult task, especially if you don’t know what to look for.

In this buying guide, we will explain the factors you need to consider when making your purchase. By considering these factors, you will be able to find the perfect subwoofer for your needs!

Subwoofer Size:

The first factor that you need to consider is the size of the subwoofer. This will depend on the size of your car and how much space you have available.

If you have a small car, you will need a smaller subwoofer. Likewise, if you have a large car, you can choose a larger subwoofer.

Enclosure Type:

There are two main types of enclosures: sealed and ported.

  • Sealed enclosures are airtight and provide accurate bass reproduction. However, they don’t allow any increase in volume or bass extension because they’re completely sealed.
  • Ported enclosures are less accurate than sealed enclosures. But, they produce more volume and bass extension because they have an opening in the front of them.

Most SPL subs are designed to fit both ported and sealed enclosures.

Power Rating:

This is the amount of power that the subwoofer can handle. The higher the power rating, the more bass it will produce. It’s important to match the power rating of the subwoofer with the power output of your amplifier.

If you don’t have an amplifier, you need to purchase one that has enough power to drive your subwoofer. Power rating is divided into two; peak power rating and RMS power handling.

  • RMS Power Handling: The RMS power handling is the amount of continuous power that the subwoofer can handle. This is important to consider because you don’t want to overload your amplifier and blow your subwoofer.
  • Peak Power Handling: The peak power handling is the amount of instantaneous power the subwoofer can handle. This isn’t as important as the RMS power rating, but it’s still something to consider.


Impedance is a measurement of how much resistance a device offers to the electric current flow. Most SPL subwoofers have an impedance of either four or two ohms.

Frequency Response:

Most SPL subs have a frequency response range of 20-200 Hz. However, some subs go down to as low as 15 Hz or up to 300 Hz.

Make sure that you pick a subwoofer that can reproduce the frequencies you are interested in hearing from your music.

SPL rating (sensitivity) of the subwoofer:

This will determine how loud it can get before distorting. If you like listening to very loud music, choose a sub with a high SPL rating so that it sounds better at higher volumes and doesn’t distort easily.

Type of material used to make the subwoofer cone:

There are three main subwoofer cone materials: paper, polypropylene, and Kevlar.

  • Polypropylene is a hard plastic that is very durable but not as accurate because it’s stiffer than paper, which means it can’t move as fast.
  • Paper is softer than polypropylene, so it doesn’t last as long. However, it has better accuracy because there isn’t any distortion when the cone moves back and forth (this will result in cleaner bass).
  • Kevlar cones hold up so well under pressure and produce great bass sound, but they tend to be expensive due to their strength (these types of cone materials usually cost more than the other two).

Voice coil configuration of the subwoofer:

There are two types: single voice coil (SVC) or dual voice coil (DVC). SVC SPL subwoofers have one wire coil on the former, and are less expensive but can only be wired in one way.

On the other hand, DVC SPL subwoofers have two wire coils and can be wired in either series or parallel.

Series wiring will make the subwoofer louder but decrease the sound quality, while parallel wiring will make the subwoofer quieter but increase the sound quality.

Most SPL subs use a dual voice coil configuration because it allows for more flexibility with wiring options.


The last factor to consider when choosing an SPL subwoofer is your budget. You don’t have to spend a lot of money to get a good subwoofer that will produce high-quality sound.

There are plenty of affordable SPL subwoofers on the market that will give you the bass you’re looking for.
