> The air density is much too low to be a good impedance match with a cone loudspeaker. Take your hand and try and grab some air or flatten your hand and try and push some air as fast as you can. This illustrates the futility of trying to move air to create a small amount of pressure at low frequencies with a cone speaker. You can barely feel the resistance of the air to the motion of your hand, the air molecules simply slip around. > Now take your hand while driving down the road and stick it outside the window of a car. The faster you go the thicker the air feels. So could you have a normal fan blowing air into a normal subwoofer to increase the pressure, and get more bass?
