.50 CAL A-BOX Reviews:

"Since receiving my 50cal I haven't stopped listening to it, the sound is quality, bass levels and midtones are incredible, played it next to both my Bose sound bars and it blows them away.
Awesome product, I will be ordering another:)
Love this thing " - Cye Hayes. Facebook review 100+ reviews scoring 4.8/5.0

"The new Bluetooth Champion" -Unbox Therapy

"Militia chic with clear and punchy sound" -Wired Magazine on the .50CAL A-BOX 

The biggest tech reviewer in the world with 21.4M subscribers on the .50CAL 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

"I expected something good but the sound is just perfect, I've got 2, 80Watts home audio speakers plugged on an 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

New anodized aluminum knobs.

New Power and volume control knob

These knobs are milled out of architectural alloy 6063 Aluminum.

The new volume knob actually goes up to 11 not just 10 and will be on all .50CAL A-BOXes ordered from now on.

The selector switch knob will be on ammo can speakers with Guitar input and/or Wifi options added.

You can also order the knob(s) separately right here if you would like to upgrade the previous generation rubber/plastic volume knob and chrome selector switch knob on your A-BOX if your A-BOX has a selector switch.

New Selector switch knob (only included when Guitar input and/or Wifi are selected)

Apocalypse Now, Anywhere.

Developed and perfected over 14+ years with the feedback from thousands of customers. The .50 CAL A-BOX is a high quality wireless speaker built into an genuine 50's design .50 CAL ammo can. The ammo box speaker is a compact power house which produces a crystal clear, full sound with great mids and surprisingly deep bass. Far exceeding your expectations for a portable speaker this size.

Next to its eye catching looks, the robust military spec design ensures it can handle bumps, drops, some rain/splashes and even some napalm which would melt any other 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, traveling or in case you need to intimidate the enemy in a war zone from a helicopter, yes, Apocalypse Now.

Thodio factory veteran production manufacturing

A peek into the workshop with our Polish veteran Robert proudly showing his work.

All Thodio speakers are built to last with a future proof design. Most older versions of the A-BOX and iBox can be upgraded and repaired with almost all of the latest upgrades. In most cases this can be done by the customer because of easy to exchange plug and play modules and parts. Saving hassle, shipping costs and time.

You can open the A-BOX up by pulling the latch on the right side just like any ammo can and show the impressive interior packed full with the latest tech. This also makes it very easy to upgrade or repair if needed.

We reinforced and insulated the ammo can speaker with 3 different materials to get it to sound as great as its hand crafted solid bamboo brother, the iBox XC does.

The new 320Watts audiophile amplifier driving the custom designed kevlar coned coaxial speakers with soft dome tweeters are what makes this box boom. Full stereo sound, louder and with more transparency than any portable bluetooth speaker you have ever experienced.
