Hello everyone, I got some questions about these speakers. I had them hooked up to my xbox 360 via optical input on the 360, ran back to the z-5500 control panel. The sound was not loud at all when at about half way turned up of the full peak? What's going on here, are they lounder on a pc with a sound card? I mean sure they sound crystal clear to me but the sound levels are not impressive at all. Am I doing something incorrect? I messed with all the settings on the control panel and have it set correctly.
