First off , I think a picture is nessessary ok ? As in the picture , the big black box is a Velodine 18 inch , 3000 watt peak power with 2 1/2 inch excursion . It is rated at 2% total distortion at 120 decibels . To give you an idea , the threshold of pain is 115 decibels , 120 can render a person unconscious . Anyhow , we had a nasty little thunderstorm and lightening struck our power pole . It fried the transformer on the pole with a loud explosion . When power resumed , I checked my equipment for damage . I have exceptional protection against all things but something happened to my sub-out unit , the power that sends signals to my sub-woofer ! It was stuck and full power pulsing at over 125 decibels ! It broke a few windows and some China , Nicky-Nacky things before I could get to the breaker ! My neighbors thought a plane had crashed or something ! Eeeek.! I spent seven hours today rewireing my unit from sub-out optical hookup to direct in line wiring and since I had built the wall around my equipment , it took awhile fishing eight wires through the wall but SUCCESS ! I can again torment my neighbors ! I'll try to include my back wall array , bad ass !
