Ok, when using the Stereo x2 effect on the Z-680's, how loud are everyone's rear speakers? Are they as loud as the front ones? 'Cos I was under the impression that Stereo x2 should, y'know, create Stereo twice. My rear speakers are barely audible, especially compared to the front ones. This happens whatever source I use, and whether I use analog or digital input.
Logitech tech support told me to turn up the rear speaker volume in Windows... an interesting suggestion considering we're only talking about stereo...
Or am I missing something?!??
