Don't know the prices on those, but another small speaker system to consider is the Omnisat from Mirage. They have an unusual design that casts a far wider soundstage than almost all speakers of their size. Imaging, however, is less precise than traditional designs. If you'll be mainly using them for movies, they might be a good solution, as they are supposed to generate a far more immersive soundfield. If the Omnisats are too big, they have a set called Omnisat Micro and an even smaller set called Nanosat (same design principle, smaller speakers). If you're planning on a lot of music playback, these might not fit the bill, but for movies, the design is promising.

From there you can find the Nanosats and Omnisat Micros as well.
