Competition vs. Regular Subs
If you’re looking for power, the competition subs are for you. Whether you’re db Drag Racing or just want subs that’ll blow your hair back, this grade is it.
There are five qualifications for competition subs:
- Power handling of at least 1,000Watts RMS
- A voice coil bigger than 2.5 inches.
- An Xmax excursion of at least 1 inch
- Spiders bigger than 7 inches
- Cones made out composite, or any equally durable material.
These factors are what enable competition car subwoofers to achieve staggering SPLs that a regular subwoofer cannot. Great power comes with compromise though.
Some people feel that regular subs are better, if you value sound quality over sound power. The sound from a regular sub may inherently sound sharper because this sub cannot emit as much of that booming reverberant bass. The competition sub is more your style if you prioritize SPL over SQ.

Another crucial variable to consider is the type of enclosure, or box. The two types of boxes are ported and closed. I won’t get too in depth with the details, but basically, if want maximum bass emission, ported is the way to go.
Structurally, the biggest difference between the ported and closed boxes is the vent. The vent in the ported box increases bass output because of the way it interacts with the air trapped inside the enclosure. If you want a more refined, crisp sound the closed box is better.
It uses the air trapped inside for shock absorption, allowing the box more control over the reverberation of the bass.
Let’s get on to the real reason you are reading this article. You want to know what subs are so powerful, you won’t be able to see what’s in your rearview mirror—that’s how much it’ll be shaking.
The Badass Seven: Final conclusions
