Product Type
Price Range
Number of Subwoofers
This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
Box Type
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.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Box Style/Shape
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 Sealed Enclosure Boxes with Car Subwoofers

    Sealed Enclosure Boxes with Car Subwoofers Frequently Asked Questions (FAQ)
    Sealed enclosure boxes, also known as acoustic suspension enclosures, are specialized enclosures designed to house car subwoofers. These enclosures are airtight and fully sealed, isolating the subwoofer's rear wave from the front wave. Sealed enclosures are known for producing accurate and controlled bass response with a focus on tight and precise low-frequency sound.
    Sealed enclosure boxes work by creating an airtight chamber around the subwoofer. As the subwoofer cone moves, it compresses and rarefies the air within the enclosure, generating sound waves. The sealed design prevents the air inside from escaping, which allows for more controlled movement of the subwoofer cone. This design results in accurate and well-defined bass, making sealed enclosures suitable for music genres that require precise bass response.
    Using sealed enclosure boxes offers several benefits. Sealed enclosures provide accurate and controlled bass response with minimal distortion, resulting in clean and detailed sound reproduction. They are well-suited for music genres that emphasize quality over sheer volume, such as jazz, classical, and rock. Sealed enclosures also tend to be more forgiving when it comes to subwoofer power handling and provide a more balanced sound across a wide range of frequencies.
    To choose the right sealed enclosure box, consider factors such as the size and power handling capabilities of your subwoofers, as well as your vehicle's available space. Select a sealed box that matches the specifications of your subwoofers to ensure proper fit and optimal performance. Researching product descriptions, reading user reviews, and consulting with car audio professionals can help you find the appropriate sealed enclosure that complements your subwoofers and audio preferences.
    Installing sealed enclosure boxes can vary in complexity based on your vehicle's space, your familiarity with car audio installation, and the specific box design. If you're comfortable with basic car electronics and following instructions, you might be able to handle the installation yourself. Sealed enclosures are generally more straightforward compared to ported or bandpass designs. However, if the installation involves custom fabrication or if you're not experienced with these tasks, seeking assistance from a professional car audio installer is recommended. Professionals can ensure proper installation, acoustic alignment, and optimal bass performance while preserving your vehicle's interior aesthetics.
