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.
"NEW BLUETOOTH CHAMPION!" - Lewis Hilsenteger (Unbox Therapy)
BUILT TO OUTLAST THE REST
Buy it once. Hand it down.
Thodio has been handbuilding speakers since 2005 — and in 2007 made the first portable Bluetooth speaker on the market, before any big name. Twenty-one years on, every unit is still handmade, repairable, and upgradeable. Swappable battery, serviceable by design. Customers from 15 years ago still send theirs in for an upgrade instead of replacing it — the kind of speaker you hand down, from son to grandson.
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.
