TRW - 17

By rotating the fins and modulating the speed, frequency goes all the way down to 1Hz, the territory of jet engines, nuclear explosions and plate tectonics. By comparison, your typical sub hits 20Hz on its best day.

Note, the model 17 must be professionally installed in an attic or basement which becomes an infinite baffle.
