Sound spreads spherically, not in a straight line.
A loudspeaker chassis is just a membrane that generates sound waves.
Without resonators, its effect is flat and limited.
Resonance is what makes the rest vibrate.
A sphere is the perfect resonator.
No diffraction, perfect refraction, no alienation.
We have perfected the surround sound.
Spatial and perceptible, even through a single sound cell.
