It's been years since we've spotted a proper handle-sporting boombox on this side of the equator (in public, at least), but we're decidedly impressed with this unique Kickstarter creation, dubbed the Berlin Boombox. Constructed nearly entirely of cardboard, save for some metal- and plastic-based essentials, the speaker rig ships disassembled in a flat cardboard box. Getting the Boombox up and running shouldn't require much effort, however -- the designer states that you won't need any tools during the quick assembly process. After you're done, you can connect the setup to any source with a 3.5mm headphone jack, then control volume with the large aluminum power/volume knob. The Berlin Boombox also ships with four AA batteries, though it's not clear how many hours of music you'll be able to pipe through the speakers with that initial set of cells. We also can't speak to sound quality, though there is a free custom sound profile available for iOS devices -- audio "will be remastered in real-time to use the full potential of the Berlin Boombox."

You can pre-order your own with a $50 pledge, saving you 9 bucks off the estimated retail price. There's also a "limited edition" two-tone box, available with a $100 pledge, while $250 will net you a custom-designed model, which can also be paired with a dinner and tour of Berlin with the inventor if you're willing to fork over $500 or more. There's just shy of two weeks left during the funding period -- you'll need to provide that financial support before noon on April 25th. The project is on track to meet its $14,000 funding goal, however, so it's fairly safe to say that you'll be able to snag one of these cardboard contraptions even if you aren't ready to take the plunge just yet.
