This Cubic satellite belongs to the Cubic 5.1 set
1 passive cubic piano-glossy subwoofer (27x27x27cm) and 5 piano-glossy satellite speakers (10x10x10cm).
Subwoofer has a warm deep bass, satellite speakers although the small size do have a clear sound in middle and in high frequencies.
If you want to have a brilliant sound not only in base and high but also in middle frequencies and do not want to have a set of big speakers, this is the right choice.
ps. you need to have an amplifier or receiver because speaker-system doesn't have active speakers.
