External Combustion Subwoofer

Very very loud

A continuous stream of fuel is sprayed into the combustion chamber over a glow plug into the small end of a cone, the large end being the speaker output. The modulation is added by the injection of varying amounts of oxygen into the ignited stream of fuel. You could also modulate the volume of the fuel stream being blown into the oxygen mixture/ignition chamber. You could also do both if necessary.

The drawback is you'd have to re-fuel it from time to time but you'd be able to move a lot of air and make a very very loud speaker.

Think of it as a V1 buzzbomb playing music, because that's essentially what it would be.

Of course, my speaker could actually rip his speakers to shreds. [doctorremulac3, Jul 01 2013]

       This would dovetail very nicely with a large Steampunk stereo. The whole assembly could be enjoyed from a reinforced underground bunker miles from Ground Zero. I like it! [+]

       // constant stream of fuel //   

       Sp: continuous   

       If you wish to modulate the volume/pressure of injected fuel (as stated), it's not a constant stream, it's a variable stream.

       Agreed. Changed accordingly to accomodate the second method of adding modulation.

       My pedantular gland thanks you.

       Just realized this is an external combustion device, not internal.   

       If I ever build one of these, the first song I'll play on it will be Brahms's Lullaby. This will privide mirth and merriment for all. Or just me, not the neighbors so much.

       Pure coincidence, last night I watched a show called "Outrageous Acts Of Science" where the guy had a speaker system in his car that could shred phonebooks and shatter glass. (see link)   

       The line between subwoofer and anti-personel weapon grows thinner every day.

       Corrected. Please forgive this terrible oversight. In the rush to war we sometimes forget to fire the ceremonial opening shot.   

       My pedantular gland thanks you as well, m'lud.
