"Militia chic with clear and punchy sound" -Wired Magazine on the .50CAL A-BOX
"I expected something good but the sound is just perfect, I've got 2 80Watts home audio speakers pluged on a amplifier, with an already very good quality but your box beat them on the punchy aspect, the gradings are just perfect, it slaps you in the face, and no vibrations, every detail is over-clean, you're a Dutch magician" -Charles D. from France on the .50 CAL A-BOX
"I received my A-BOX about a week ago. I love it! Great design, great sound. Can't wait to hit the beach with it this summer! Thanks again for the great product" -Joseph P. from the US on the .50 CAL A-BOX
"The sound is amazing!!!!! I have no idea how so much sound can come out of such a small box!! and a metal one at that!! Absolutely fantastic job mate! Worth every penny. Well done sir" -Jose R. from the US on the .50CAL A-BOX
Apocalypse Now
Developed and perfected over 7+ years with the help and feedback of thousands of satisfied customers, the .50 CAL A-BOX is a wireless bluetooth speaker built into an original 50's design .50 CAL ammo can. The A-BOX is a compact power house which produces a punchy clear sound far exceeding your expectations for a portable speaker this size. It's ready to be taken to the "party"field and beyond.
Next to its truly eye catching looks, the robust military spec design ensures it can handle bumps, drops, some rain and even some napalm that would melt any other plastic speakers on the market.
You can use these wireless speakers anywhere at any time. Whether you’re at home, in the park, at the beach or in case you need to intimidate the enemy in a warzone from a helicopter, yes, Apocalypse Now.
We reinforced and insulated the ammo can with 3 different materials to get it to sound as great as its hand crafted solid wooden brother, the iBox XC does.
The 200 watts RMS audiophile amplifier driving the custom filtered kevlar coned coaxial speakers with softdome tweeters are what makes this box boom. Louder and with more transparency than any portable bluetooth speaker or boombox you have ever experienced.
Everybody in the neighborhood will know who is coming when you turn this baby up, whether youre inside the house or outside…

BORN FOR THE OUTDOORS
Built like a tank. Sounds like a concert.
The tailgate. The trailhead. The middle of the desert. A real .50 CAL ammo can shrugs off rain, dust, drops, and heat — then plays loud enough to own the space. Throw it in the truck and forget about it.
BUILT TO OUTLAST THE REST
We built the first. We're still building the best.
In 2007, the iPhone had just landed and music was moving off the CD and into your pocket. That's the year Thodio built the world's first portable Bluetooth speaker. Every unit since is handmade, with a swappable battery and serviceable by design. Whatever year yours was built, we bring it up to current spec. This is the one you keep.
Questions
What if I don't love it?
Try it for 60 days. If it's not for you, send it back for a full refund — including return shipping. No restocking fees.
Is it really weatherproof — how tough?
It's built from a real .50 CAL ammo can: sealed steel that shrugs off rain, dust, drops and heat. Made to be thrown in a truck and abused. (Tough by design — not tested to a specific IP rating.)
How loud does it get / will it fill an outdoor space?
320 watts of full-range output — loud enough to fill a backyard, a beach or a campsite and own the space outdoors.
How long does the battery last and how do I charge it?
Choose your pack: 34, 68 or 102 hours of playtime per charge — up to about a week on the largest. Recharges over USB-C fast charging.
What's the difference between Standard Issue and Fully Loaded?
Standard Issue ($539) = Bluetooth + USB. Fully Loaded ($679) = Bluetooth + WiFi + guitar input + USB. Both come in Olive Drab or Black Ops, with your choice of battery.
Is it really built from a real ammo can and handmade?
Yes. Every A-BOX is hand-assembled in the Netherlands from a genuine .50 CAL ammo can. Thodio has handbuilt speakers since 2005.
How long does shipping take?
Free worldwide shipping with tracking. (Add your exact dispatch/delivery window here.)
READY FOR THE OPEN AIR?
320 watts. A week of playtime. Built to be abused and to outlast it all.
