quick question: can i connect a wd hd media player, xbox 360 and my cable box to this, all via hdmi? Im a newb with soundbars. The plan is to connect the 550w to my tv, then connect the three devices to the soundbar. Will this work? No other cables are needed if im doing all this thru hdmi, correct?
Also, i have a subwoofer from my onkyo HTIB, which i plan to stop using. Can i connect that subwoofer to this, instead of the initial one it comes with?
