Arms22 shares this oddly stealthy example of DIY audio - converting a couple of empty grandes into computer speakers using a TDA1552Q amplifier chip. Nice reuse - looks natural too! The relevant page is in Japanese but you can still check out the schematic - Coffee cup speakers

Objectively: Nice reuse. Nice clean setup.
Subjectively:
The cynic in me is looking at the setup and can't help but think that a person who uses this setup is 1) very cool for the good reuse, but 2) someone who would make me throw up a bit in my mouth because of the relative trifecta of Mac / Starbucks / Pottery Barn fanboy factor. Interesting that the feng shui appears to be catalog perfect, but the sheer obnoxiousness exuded by the picture is enough to make some geeks regurge. It's like matching sweaters at the ski lodge.
That said, I'll probably go make some too...just have to figure out what status beverage and salvaged Nantucket wood goes with my homebrew machine. Coming next week to Make: Yoohoo speaker stands!

The casing around a speaker actually has a function (in addition to any aesthetics). It prevents the sound wave generated from the back side of the speaker membrane to cancel (or distort) the sound wave from the front of the speaker. Making an airtight space gives rise to some problems with resonance inside the box resulting in uneven frequency characteristics, or so I would think. I don't understand why so many make speaker casings out of paper when there are plenty of sturdier materials to choose from?
