From the web:
Minimus-77 Metal Cabinet Speaker Systems use the same design that won
raves from audio critics for pace setting performance in small speakers.
They are small only in size, not sound! A high-compliance woofer
provides outstanding bass, while the dome tweeter produces crisp, detailed
highs. Careful acoustic design matches the two dynamic elements with the
enclosure and damping materials, resulting in amazingly smooth and broad
frequency response.
