how to laser tune a speaker? Laser interferometry. Celestion ditton used it to refine their tweeter design in the 80's and the results were stupendous.
Bose really did try to go beyond physics saying that you do not need a low mass driver to accurately reproduce high frequencies.
Laser interferometry is used to ensure that your drivers are not physically distorting. You can also use it to calibrate cnc milling machines, or find welding faults, or for many types of testing.
