Maybe you know about ATC and its state of the art loudspeakers. In case you don’t, I think the best way to introduce the UK manufacturer to you is by showing you their Concept 6 sound system.

ATC claims that the C6 is the ultimate expression of multichannel performance, providing an open-ended upgrade path to perfect sound reproduction. These are just words, you’d say. Sure any manufacturer tries to promote their products by saying all sorts of misleading stuff. That’s not the case with the C6, though. What would you say about a 2750W RMS Active system lying around in your comfy crib?

The system is actually made up of four separate ATC products that can be arranged in 5.1 or 7.1 surround systems. You get to choose between ATC's world-acclaimed SCM50ASL professional three-way active reference loudspeaker that is built to provide outstanding sound for left/right channels. Upping the standard, you can throw in a couple of levels of SCM100 or 150 monitors, while the rear surround component is provided by the SCM20AT which, again, may be upgraded to SCM50 or 100 monitors. You can even get an optional second C6 Subwoofer transforming your system into a X.2 one

For more information on specs check out this official page. Of course this is no cheap system and for an X.2 configuration you might want to make the leap for $20,000.
