Very Small Desktop Speakers


Can anyone give me advice on small to very small speakers that could sit on a desktop? I have moved to a new open office situation where I have walls but no ceiling so my old Plinius 8200 and B&W 805 speakers are just too instrusive to some the others around me. My source would be my Apple powerbook or maybe a small CD player. Let's face it, sound quality is not the most important issue but size is. I was thinking of a Sophia "Baby" amp or something equivalently small--so speaker efficiency is also a consideration.
thanks for the tips in advance.

newegg.com, search on swans. Kinda on the big side but no sub required, perhaps. Swan makes their own drivers here and abroad, but an excellent value, much stronger than most plastic 'puter spkrs. Just don't tell WSJ's Mossberg.
NHT Super Zero. These a great speakers, period. The Super Zero XU model is still in production, but probably won't be for long.

Maybe too tall at 19", but consider the Thiel PCS.
