I will boast about the time I dropped 2 X 10" subwoofers into my home theater (in the family room) and it took my wife 2 weeks to figure out that they were there. And she didn't see them but she heard them: "What's that noise?" "That's bass, dear."
Now that is funny. My son was insistent that I needed a powered sub when I was hooking up my system. His jaw dropped when he finally heard it for the first time.
'I can hear why you don't need a sub Dad' was all he could say when I demo'd it to him the next time he was home.
My wife complains about the bass on the TV shows I watch. It's amazing how much is there if you have the right equipment to listen to it.
I usually use the fight scene in 'Sherlock Holmes' to demo my system now. You can feel the bass before you hear it.
