I had a buddy of mine that spent a fortune on a home theatre system for his house in the early 90's...
Laserdisk
Surround sound
World class speakers and a Power amp that was louder than ...
Anyway, I am over there watching Terminator 2 and he had the thing cranked to about 5... It was so loud that the police dept got over 100 calls from people in the neighborhood complaining of hearing guns shots.
They actually thought somone was firing off Live ammunition.
