The Soundscience Rockus 3D 2.1 Speaker System from Antec comes with one unique feature: 3Dsst™, which is a suite of DSP algorithms that create a virtual surround sound experience from 2.1 stereo speakers. The subwoofer is rated 100W, and the sattelites 25W; the speaker system packs quite a punch and can be connected easily on optical to our preferred sound sources.
