I’m not certain what the world 3D sound means, but Antec’s soundscience rockus system has clarity and accuracy of high-fidelity audio.
As you can see, it comes with two satellite speakers made of anodized aluminum. The system has 25 Watt speakers and 100 Watts per subwoofer. The frequency response is 10Hz to 20kHz.
The 3D effect can be switched on and off with the control pod, allowing the viewer to switch between optical and analog inputs. There is also some optical input for the playback of digital audio from game consoles like the Xbox360, PS3, and other equipped devices.
You should be able to purchase the Antec soundscience rockus 3D 2.1 speaker system for about $249.99.
