These are great speakers but we have got rid of the pc they were linked to! There is a heavily reinforced, cube-style 17 watt RMS subwoofer with protective coating for solid bass and durability, along with 4 satellite speakers of 6 watts RMS each, with contour around drivers for improved sonic imaging. There is realistic 3-D positional audio on EAX-enhanced and Microsoft DirectSound 3D games. Magnetic shielded satellites safeguard your monitor. A bargain price to create space (I've seen 2 replacement speakers for £20)!
