When it comes to subwoofer boxes, the most preferred and common type of subwoofer enclosure is the best ported subwoofer box design. As a car owner planning on doing some major car stereo systems upgrade, a subwoofer will most likely be at the top of the list. Choosing the best subwoofer enclosure box for most car owners with less of technical background in car audio can be a hell of a task. Do not worry nor despair because we at carsaudio are majors in car stereo systems and components, hence we got you covered.
If you are planning to buy a new aftermarket subwoofer for your car, most likely it will come just as a speaker unit with no box enclosure. Most subwoofer speaker manufacturers do not include an enclosure box because there are various types of them, hence the car owner is at liberty to choose which one suits their car audio needs.
Some car subwoofer manufacturers may consider the buyer’s needs and manufacture a complete unit where the subwoofer speaker comes pre-installed with a subwoofer enclosure. This saves on the time required to shop for a ported subwoofer box enclosure. If you are a good DIY guy, you can build your own subwoofer enclosure box of your own liking and design although it needs tools and materials hence a painstaking process.
The ported subwoofer enclosure is the most common one whereas there are other types such as sealed subwoofer boxes and bandpass subwoofer boxes. We have broadly covered these subwoofer enclosure boxes in a separate article. In this article, we are going to focus on the best ported subwoofer box design available in the market today. They are of various shapes and sizes.
Ported subwoofer box enclosures are preferred due to their forceful, loud and punchy bass production. The vent called a port is used to reinforce low bass response where you get more bass output than you would on a subwoofer box. Ported subwoofer boxes are easy to identify physically where you just need to look for the port on the subwoofer enclosure.

Factors to consider while choosing a ported subwoofer box
The following factors will assist you in choosing the best ported subwoofer box design in the market today without any compromise to bass sound quality and subwoofer performance. They include:
a) Subwoofer size: This is the main governing factor for best ported subwoofer box design. Before anything else, ensure that your subwoofer fits in the subwoofer box perfectly with adequate allowance to cone movement. This is quite important because the box enclosure really influences the bass quality. Therefore, you need to check on subwoofer size ratings because an enclosure box for an 8-inch subwoofer might not be workable for a 12-inch subwoofer. This is quite important to know before shopping for a ported subwoofer box. Car subwoofers range from 8-inch, 10-inch, 12-inch, and others go up to 15-inch in diameter. Therefore, you should choose a subwoofer box that meets the size of your subwoofer for proper compatibility and fit.
b) Number of subwoofers installation: Some car audio aficionados would prefer to install multiple subwoofers into their car stereo system. This should not make you worried because a ported subwoofer enclosure will still remain the same technically where the only difference will be just an extra opening for an additional subwoofer. That’s it! The purpose is to get more loud bass audio output from your car’s subwoofers. In the subwoofer enclosure market, it is very easy to find dual subwoofer enclosure boxes. We are going to review some in this article shortly.
c) Subwoofer enclosure box dimensions: Dimensions are a key consideration especially if you are to build your own ported subwoofer box from scratch. Wrong dimensions will definitely lead to inaccurate subwoofer installation leading to sound distortion. The common subwoofer box installation in a car setup is at the boot or behind the rear seats. This space is meant for luggage hence there is a need for economic space usage. Check dimensions carefully to avoid the disappointment of having a new best ported subwoofer box design that cannot fit into the space available. Generally, all subwoofer boxes for deep bass have a dimensions rating of 20-inch by 15-inch by 15-inch which should be able to fit properly in your car’s boot properly.
d) Durability: this is a crucial factor worth considering. The subwoofer box must be durable and able to sustain the vibrations caused by the air displacement caused by the subwoofer speaker units when its cone displaces air. Therefore most subwoofer box manufacturers have ensured that their boxes are fixed tightly with glue and screws in order to secure the MDF boards mainly used in the manufacture of subwoofer boxes. Even after prolonged usage, the subwoofer boxes should be free of vibration, rattle and flex.
e) Construction: Other than the durability of your subwoofer box, its construction can also affect its audio quality. Generally, all subwoofer boxes for car installation will be made out of MDF boards, which is considered to be pretty good for audio quality. However, not all subwoofer boxes use the same type of MDF boards since you can find 3/8-inch and 5/8-inch thick MDF options. And out of these two options, 5/8-inch MDF construction is better for deep and loud bass output. The MDFs should be glued up properly and screwed to increase the structural integrity of the subwoofer box. The chambers should provide no-leak, no-rattle conditions.
f) Warranty: Just like your subwoofer, you would also want your subwoofer box to be reliable and ideal for long term usage. Because of the same, checking the warranty included with your subwoofer boxes for deep bass can also be a great idea. Usually, you will find subwoofer boxes to include either a 1-year warranty or a 2-year one which should be plenty when it comes to the reliability and durability of your subwoofer box.
While such factors can be quite handy before buying the best ported subwoofer box design of your choice, you still need to keep a lot in mind before buying one. Hence, the various ported subwoofer boxes for deep bass given here also have their significant features and options provided. It is quite important to carefully read through this article to the end.
