Belva Ported & Vented Subwoofer Boxes

This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Refers to the diameter of the subwoofer, measured in inches.
This is the shape of the enclosures cutout hole and defines the style of subwoofer that can be installed.
The color of the enclosure's exterior/outer finish.
The internal volume measurement in cubic feet before subwoofer magnet displacement.
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.

    FAQ Frequently asked questions in Belva Ported & Vented Subwoofer Boxes


    Ported & Vented Subwoofer Boxes Frequently Asked Questions (FAQ)
    A ported subwoofer box is a type of subwoofer enclosure that has a port or vent that allows air to flow in and out of the box. This type of enclosure is designed to produce deeper, louder bass response than a sealed subwoofer box.
    There are several benefits to using a ported subwoofer box. First, ported subwoofer boxes produce deeper, louder bass response than sealed subwoofer boxes. Second, ported subwoofer boxes can be more efficient than sealed subwoofer boxes, meaning they can produce more bass with less power. Third, ported subwoofer boxes can be more forgiving of placement than sealed subwoofer boxes.
    There are a few drawbacks to using a ported subwoofer box. First, ported subwoofer boxes can be more difficult to build and install than sealed subwoofer boxes. Second, ported subwoofer boxes can be more expensive than sealed subwoofer boxes. Third, ported subwoofer boxes can be more sensitive to changes in air temperature and humidity than sealed subwoofer boxes.
    When choosing a ported subwoofer box, you should consider the following factors: The size of your subwoofer The amount of bass you want The space you have available Your budget Your personal preferences
    Installing a ported subwoofer box is a relatively easy process. Most ported subwoofer boxes come with instructions, and the installation process should only take a few hours. Here are some additional tips for installing a ported subwoofer box: Make sure the box is secure and will not move around. Seal any gaps or openings in the box to prevent air leaks. Position the subwoofer in the box so that the cone is facing forward. Connect the subwoofer to your car stereo. Experiment with different settings to find the sound you like.
