The uCube speakers are small and sleek looking with 15 watts of power per channel. The power comes from your USB port, which makes them perfect for traveling.
They come with a Balance Mode Radiator or BMR, apparently this produces a full frequency range with a wide dispersion pattern; I think this means the sound quality is pretty good.
The speakers themselves are 3.25” square and also come with a Digital Signal Processing DSP amplifier.
They defiantly look the part, you can take the stands off for a minimalist look; goes great with the MacBook. The UCube speakers will cost you $149.99 and are available at ThinkGeek.
