Thodio A-Box

With its wartime ammo box design, one might consider the Thodio A-Box ($340-$475) their portable sonic arsenal. Available in two models — one with a 2 x 25 Watts amp and woven glass speakers, and a heavier-duty one with a 2 x 70 Watts amp and woven kevlar speakers — the A-Box is made from 1mm steel plate fortified and covered in vibration damping material to keep the rattles at bay, and features indication lights in the bass tube to indicate battery status, as well as an integrated handle — like the ammo boxes of yore — and army-style paint and markings. Good luck trying to get it past airport security, though.
