True, but I don't really see the point. They're better than before, but the laws of physics dictate they'll never be good. If I can't use good speakers I'd rather use headphones. Sacrificing efficiency doesn't matter when the driver is so close to your ear it doesn't need to be loud.
- ta988 3y agoWhich laws of physics are you refering to? To my knowledge, there is no law that says that a tiny driver of arbitrary geometry (could be multiple tiny drivers) couldn't reproduce arbitrary pressure patterns in the audio frequency and intensity range.

Also, even if efficiency was not a concern (maybe you don't pay for your own electricity and you somehow managed to build superconducting voice coils and speaker cables), getting arbitrarily high pressure from an arbitrarily small driver requires arbitrarily large excursion. If you somehow overcame all the mechanical complexities of this, you'll still run into the problem of finite speed of sound. The higher the excursion the faster the cone moves for the same frequency, and at some point it's going to go supersonic, which is certainly not good for distortion.
