My wife and I were watching VH1's One Hit Wonders.
They showed a video from Autograph - Turn it up the radio...
Well, my living room is 14' tall with a surround system and 4' tower Advent front speakers.
My wife and I turned it up less than half it's capacity.
My 10 year old daughter started telling us to turn it down.
I told her "If it's too loud then you're too old"
