Replacing your vehicle’s old fa tory speakers with 6x9 speakers is a sure way to improve your audio listening experience.
An even better trick involves installing the speakers in an enclosure. The box helps intensify the bass of these speakers—which helps precisely bring out the highs and lows of your favorite tracks while saving you the money you might have invested in a woofer or amplifier.
That said, you can opt to buy a pre-made 6x9 speaker box or make your own.
If you go with the latter option, you’ll be able to save some cash and learn something new in the process.
Below, we’ll guide you through the most popular 6x9 speaker plans, and helpful tips for creating your own 6x9 speaker enclosure at the comfort of your home.
The Most Popular 6x9 Speaker Plans:
1. Sealed/closed 6x9 speaker box
If you want tight and precise bass, this is the ideal speaker box for you.
As the word suggests, the design involves a completely sealed, airtight box. It works on the principle that when your speaker moves, the air doesn’t escape from the box. Instead, it alters the pressure inside to help control the cone movement.
This is also the easiest speaker plan to design as you only need to calculate the internal volume of the box. They also require the least materials, making them cheaper to build.
Not to forget that the sealed 6x9 speaker plans are incredibly compact, which means they require minimal space in your vehicle.
However, keep in mind that sealed box designs require more power than the ported enclosure, so we advise you to hook it with an amp with ample wattage to facilitate optimal performance.
2. Ported/vented 6x9 speaker box
For car owners who crave for a forceful, aggressive base, you’d be better off housing your 6x9 speaker in a ported/vented box.
This is made possible by the fact that this enclosure features a tuned vent that incredibly boosts the output of low frequencies (which is basically the bass).
So, if you listen to a genre such as rock, heavy metal, rap, and the likes, a vented speaker will grant you a mind-blowing audio experience.
For you to accomplish the forceful bass, however, these boxes need to be much larger than the sealed types…meaning you’ll need to use more materials.
3. Bandpass 6x9 speaker box
Bandpass boxes are usually special versions of vented enclosures and will help you achieve maximum slam.
In these boxes, you mount your 6x9 speaker inside a chambered box, where one box is sealed, and the other is vented, with the frequencies emerging from the ported box.
This way, these boxes achieve optimal efficiency within the band’s range, which enables them to deliver maximum boom or slam.
Bandpass boxes also tend to exhibit excellent power handling capabilities within the band range.
Due to the dual chamber design, you can expect these boxes to appear larger. And might not suit your needs if you have limited space.
The fact that they produce big sound means they tend to sacrifice the low-frequency responses.
4. Isobaric 6x9 speaker box
In this enclosure type, you align up to two 6x9 speakers mounted in a face to face manner, with one of them wired in reverse polarity.
The idea behind this design is to help facilitate alignment for effectively dividing the duct into a half.
One of the key advantages of using this type of enclosure is how excellently it cancels out any distortions to provide you crisp audio quality. The isobaric principle also boosts power handling capacity.
The act of housing two speakers in a single box also means they’ll occupy less space in your vehicle.
However, you’ll need a lot of power for this alignment to work efficiently. You’ll need to invest in high-end amp and an equally capable stereo system.
