Trinity Audio Subwoofer Boxes for B, M and H Series Builds

A subwoofer enclosure has a major effect on how the finished system performs. Matching the box to the subwoofer application gives you a much better starting point than choosing an enclosure based only on woofer diameter.

The current BassHead Supply Trinity Audio lineup includes enclosure options for Trinity B Series, M Series and H Series applications, with single and dual configurations across popular 10-inch, 12-inch and 15-inch bass systems.

Trinity Audio B Series Subwoofer Boxes

BassHead Supply offers several enclosure choices for Trinity Audio B Series builds. Current listings include single and dual ported designs for 10-inch, 12-inch and 15-inch applications.

10 Inch Trinity Audio Subwoofer Boxes

A 10-inch Trinity Audio setup can be a good choice when enclosure space matters but you still want a serious bass system. The current lineup includes 10-inch B Series and M Series BassHead Supply ported enclosures in single and dual configurations.

Before ordering, verify the exact Trinity subwoofer series, number of woofers and available space in the vehicle. Two 10-inch subwoofers require a very different enclosure and system plan than a single 10-inch setup.

12 Inch Trinity Audio Subwoofer Boxes

12-inch subwoofer systems are a popular choice for customers looking for a balance of output, enclosure size and low-frequency performance. BassHead Supply offers Trinity Audio B Series, M Series and H Series enclosure applications in this size.

A 12-inch box should be selected around the exact subwoofer model and system rather than assuming every 12-inch woofer belongs in the same enclosure.

15 Inch Trinity Audio Subwoofer Boxes

For larger bass systems, the current collection includes 15-inch enclosure options for Trinity B Series, M Series and H Series applications. Both single and dual configurations are available for customers building around one or two 15-inch subwoofers.

Larger enclosures require careful planning for vehicle space, amplifier power and electrical support, especially when moving into dual-subwoofer systems.

Single vs. Dual Trinity Audio Subwoofer Boxes

Single Trinity Audio Subwoofer Boxes

A single-subwoofer enclosure is a strong option when you want to conserve vehicle space, simplify amplifier requirements or build around one high-output subwoofer.

A properly planned single-sub system can still produce serious bass when the enclosure, amplifier, electrical system and tuning work together.

Dual Trinity Audio Subwoofer Boxes

A dual enclosure gives the system more cone area and can support significantly more output, but it also requires more vehicle space and usually places greater demands on amplifier power and electrical support.

Before choosing a dual enclosure, make sure the complete system is planned around two subwoofers rather than simply choosing the largest box that will fit.

Ported Trinity Audio Subwoofer Enclosures

The current BassHead Supply Trinity Audio products in this collection use ported enclosure designs. Ported boxes are commonly chosen for systems where strong output and low-frequency performance are priorities.

The enclosure still needs to match the specific subwoofer application. Internal volume, port design, tuning, subwoofer displacement and vehicle space all matter to the finished result.

Why Use a Subwoofer-Specific Enclosure?

A generic box may have the correct hole diameter and still be a poor match for the subwoofer. Subwoofer-specific enclosures are intended to give customers a better starting point by designing the enclosure around a particular woofer application rather than only its nominal size.

That is especially important when building around higher-output equipment where the enclosure can quickly become the limiting part of the system.

Complete Your Trinity Audio Bass System

The enclosure is only one part of the system. You still need the right subwoofer, amplifier, wiring and electrical support for the power level you are planning.

If you previously purchased car audio equipment from another retailer and need a new place to finish or upgrade your system, Audio Sellerz can help you match the enclosure, subwoofer, amplifier and supporting electrical equipment.

Owner Aaron Bryant has been involved in car audio since 2008, with experience ranging from daily-driver systems and custom enclosures to competition builds, wall builds, amplifiers, subwoofers and electrical upgrades.

Are the Trinity Audio boxes ported?

Can I use one of these boxes with any Trinity Audio subwoofer of the same size?

Do not assume that two subwoofers with the same nominal diameter require the same enclosure. Match the box to the specific Trinity Audio series and subwoofer application shown on the product page before ordering.

Should I choose one subwoofer or two?

That depends on your available vehicle space, amplifier setup, electrical support and desired output. A properly designed single-subwoofer system may be the better choice when space or power is limited, while a dual system can provide additional cone area when the rest of the system is built to support it.
