Simple really, A family member was comparing his cheap 5.1 kit to my soon to be rather expensive hi-fi. He asked why its only 70w per channel when his 5.1 kit puts out over 1000w. And I couldnt think of an answer! lol So how do they get away with it, because if you can drive a 2grand floorstander with 50-100w of quality amplification then why do these cheap £300 set quote 1000W plus! Surely they arent really that powerfull!?
