I throw everyone a curveball, or nearly everyone.... I vote that the speaker for the 21st century will be the successful development of the hypersonic speaker. Prototypes exist and work, but not to the performance needed. When the science figures it out, it should theoretically be the best speakers available.... It is based on the physics that when 2 musical frequencies are played, each tone is played, as well as the sum and difference of the two tones. Therefore, if we have 1 speaker playing at say 100,000 Hz, we'll never hear it. If we have a second playing at 100,002-120,000Hz Range, the additive sound is also silent to the human ear, but the difference should give one a 2-20,000Hz range.
The difficulty w/ most drivers is that they need to play from 20-20,000Hz, or a span of 100,000% of minimum frequency. Entirely too much to handle w/ 1 driver. If we now make a driver that plays from 100,002-120,000Hz, we only need to make a driver capable of 20% over minimum frequency... The should be MUCH easier to therefore accomplish the entire audible frequency range w/ 1 pair of drivers....
Cheers all.
