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.
