Just a few Recent Builds

At Atrend, we’ve been building subwoofer enclosures for over 30 years. From simple daily setups to full custom builds like the ones you see here, everything is built with purpose, precision, and real experience behind it.

You tell us what you’re running, what space you’ve got, and what you want out of your system — we handle the rest.

Want something clean and simple? We’ve got you.
Want something overbuilt with thicker baffles and internal support? No problem.
Want something that stands out with windows, lighting, or custom finishes? That’s what we do.

Our boxes are built to last. They don’t flex, they don’t fall apart, and they’re designed to get the most out of your subwoofers.

Fast turnaround, real support, and no guesswork.

If you’re tired of trying to make a prefab work, it’s time to do it right.

Yes, that’s a full-grown man sitting inside the box.

This was a 6 × 15" custom build, and it’s still not finished. Next step is a carbon fiber faceplate and a massive top vent.

All 1" construction, built for serious power and serious output.

Some builds are big.
Some builds are massive.
And then there’s this.

That’s the kind of stuff we get into with BYOB.

This one is just different.

All 1" construction, red interior, acrylic windows, and LED lighting throughout. You can change the colors from your phone or remote depending on the vibe.

Built to handle power, but also built to stand out.

That’s the whole point of BYOB. Some builds are all about performance. Some are about looks. Some are both.

This one does both.

This one came out clean.

2-inch birch front baffle, 1-inch birch all around, triple sanded and finished in our dark stain. Built solid, looks even better in person.

Every box we build is different. Some need thicker baffles, some need extra internal support, some need very specific tuning to match the setup. That’s the whole point of BYOB — it’s built for you, not pulled off a shelf.

If you’ve got a setup in mind, we’ll build around it.

This one is WILD.

Just wrapped up a custom enclosure build for SIX 18” subwoofers.

To give you an idea of the scale… our employee is literally inside the box. 😳

This enclosure is built extremely heavy-duty and will be shipped on a pallet to the customer once complete.

Before the internet engineers jump in — yes, additional baffle supports are still being installed under each cutout. This is just a progress shot during the build process.

When you’re dealing with six 18s, everything has to be built serious and overbuilt — from the structure to the bracing.

At Atrend, we’ve been building custom enclosures for over 30 years, and projects like this are exactly why our BYOB (Build Your Own Box) program exists.

If you want something built specifically for your subs, your vehicle, and your goals, we can make it happen.

Custom Premium Birch Up-Firing Subwoofer Enclosure – Just Completed

Built for serious bass and a true custom finish, this enclosure features a 2-inch thick premium birch up-firing top panel with flush-mounted subwoofer insets for a seamless, integrated look. Additional internal bracing is being added under the top panel, bringing that section to a full 2 inches of reinforcement—because flex is not invited to this build.

Designed to house four up-firing subwoofers, this enclosure delivers powerful, controlled low-end performance. Finished in a rich dark stain, the natural birch grain is on full display for a clean, high-end look.

Built right, not rushed.

Custom Yellow Carbon Fiber enclosure built from all 1″ material for maximum strength and performance. Featuring full see-through acrylic windows and interior lighting, this box lets you showcase the build just as hard as it hits.

Every detail is custom — dimensions, tuning, materials, finishes, windows, and lighting — built exactly how you want it.

If you can picture it, we can build it.

🔥 18” CUSTOM PREMIUM BIRCH ENCLOSURE IN THE WORKS! 🔥

Check out this beast we’re building for one of our customers — actually two identical units headed his way! What you’re seeing here is the enclosure right after assembly, before any of the finish work begins… and it’s already a tank.

🔸 18-inch subwoofers firing up
🔸 Vertical front port on the bottom section for max airflow
🔸 3-inch Premium Birch baffle up top for insane strength
🔸 Full internal bracing throughout
🔸 Will be sanded → stained → sanded again → re-stained
🔸 Finished with a clear coat per customer request

This is the kind of enclosure you build when your woofers need a real home. House-shaking bass is on the way for this customer. 🔊
