    Propane Powered Sub Woofer

    Gents

    what would be involved in building a propane powered sub woofer?

    Propane,
    Oxygen
    Strategically placed multiple combustion chanbers
    computer controlled fuel injection system




    balls of steel?

    would it be within the realm of possibilty?

              Dude... that sounds totally do-able!

              The max db and frequency range would depend much on the pressure and expansion rate of the propane, size of the chamber, efficiency of the link between the chamber and the driver (unless the driver were actually part of the combustion chamber), and how quickly and precisely the propane could be ignited and the chamber filled again.

              Even so... figure with a six-cylinder engine idling at 800 RPM has each piston firing at a rate of about 133Hz... so a a sub with an upper range of 120Hz seems achievable. Limiting the upper range to 80Hz would probably increase volume substantially.

              I could talk to the folks at Sunfire about this... but I doubt that Bob would sign off on the "True Sub C3H8" even if it did have applications for the high end built-in outdoor propane grill/patio theater market...

                  I recall reading an article years ago in Pop' Mechanics that described a huge 'flame' loudspeaker mounted on a helicopter to broadcast to a large crowd below.
