Hello everyone! My first thread here but fear not, I try to avoid to be FAIL-stamped on my forehead. :bigsmile:
I am just trying to generate brainstorm and conversation here among the DIY folks by asking: 'Do you remember Sensurround and film called Earthquake? Well to be honest I don't because I was not born back seventies, but in Sensurround equiped theatres they achieved 120dB SPL at 5Hz therefore simulating actual feeling of an earthquake!
From wikipedia, Earthquake (film)
What is needed to generate 120dB SPL at 5Hz in normal Hometheater? I am especially interested what DIY guys/gals have to offer.
If it is hard to achieve in small HT conditions then imagine what kind of systems they had in 1970 when Sensurround debuted. :yikes:
I myself have a long way to go until I reach the level of 120dB at 5Hz, but my ongoing 'Dual Exodus Audio Shiva-X sealed' -project is a good start to reach that high level punch. :boxer:
Discuss and feel free to comment and flame me. :yes:

Now for the real question!Wikipedia said:A famous example is Grauman's Chinese Theater in Hollywood, California, where the "Sensurround" cracked the plaster in the ceiling. Ironically, the same theatre premiered Earthquake three months later – with a newly-installed net over the audience to catch any falling debris – to tremendous success.
The "Sensurround" process proved to be a large audience draw, but not without generating a fair share of controversy. There were documented cases of nosebleeds generated by the sound waves.
