Each one of these miniature speaker kits from Japan’s Princeton is a DIY papercraft project. You’ll need glue, scissors, and X-Acto to assemble these models for yourself (assembly manual here). There’s three different designs to choose from, including a red boom box, a bookshelf stereo and an old cabinet hi-fi system.
Each one has a compact USB-powered NXT (mono) speaker module that sits inside to give you decent quality sound out of a paper box. To give you a sense of the size of these things, the old fashioned stereo console measures about 6-inches wide, and it’s the largest kit.
For those of you in Japan, you can order from Princeton Direct for ¥1980 each. Worldwide orders are available from the Japan Trend Shop for $35 (USD) each.
