A 15 inch subwoofer is a great way to get that extra “thump” you hear coming out of many cars. Stock audio systems have always left something to be desired. This is especially true when talking about bass. Although auto manufacturers are improving their sound systems with every passing year, it can always be better.

The good news is that newer models offer upgraded sound systems but at a substantially higher price. Often enough, the bass is not that much better even with a premium sound system. An aftermarket subwoofer will make all the difference when it comes to music’s low notes. Feeling that bass in your bones is something that can’t be easily duplicated.

We have tested four of the most popular 15” subwoofers on the market and have a lot to say about every single one. But, like most things, only one can be victorious. In our case, the Skar Audio EVL-15 has reigned supreme.

But what makes one subwoofer better than the next? Our expert team had the opportunity to test out each unit based on several factors. This comprehensive testing procedure ensures that no part of the subwoofer was left out.

Just like you, we have been on the quest for better car audio for years. Installing countless audio systems gave us the right knowledge and trained our ears to spot even the most subtle differences between subs.

That is why, after much deliberation, we have chosen the EVL-15 as the best out of our lineup. Several factors come into play when choosing a winner. In the case of car audio, looks won’t always get you to the winner’s podium. You must be able to “feel” the difference, and the folks over at Skar Audio did just that.

Benefits Of Choosing a 15” Subwoofer

In the world of subwoofers, bigger is always better. A 15” subwoofer comes with its own set of unique benefits. While some people choose 12” or even 10” subs for their car, having a bigger diameter subwoofer will outperform them in most situations.

Choosing a bigger sub, such as a 15”, will help move a greater amount of air. What does that mean? Simply put, it means that your sound system will be able to hit those lower frequency notes and let you “feel” the sound that much more.

If you want that mirror-shaking, hair raising, hard-hitting bass, a 15” subwoofer is the weapon of choice. Although smaller subwoofers, may help in achieving those low notes, nothing compares to a bigger diameter driver that can substantially move more air.

Size

In the case of subwoofers, size is particularly important. Too small and it will not produce enough bass. Alternately, an overly large sub can distort the quality of the sound if installed incorrectly. Do your research on what size is right for your application instead of finding out the hard way.

Power Rating

The power rating can be the deciding factor for most people. Although power doesn’t mean quality, it can help potential clients in deciding which unit to go for. It is important to note the operating wattage, which is usually half the max rating found on the box.

Build Quality

It goes without saying that products built to a higher standard will outlive cheaply made products. In most cases, this will mean a higher price, but there are some exceptions out there, like the ones listed on this list.

Frequency Response
