They mention efficiency, but not power. I don't like how this is framed as the general future of all speakers when it's really just the future of midrange drivers.
_Might_ be the future of mids, but I doubt it. Advancement in ribbon speakers is more likely IMHO. Also people develop a taste for how some speakers sound. I don't see guitar music being played on anything too different for a while, unless it has the same sound character. Even if technically it's a better reproduction, it has to reproduce how paper cone speakers sound now better than paper does. Seems unlikely. To win, people have to like the new sound more, or not be able to tell the difference.
I get it.
But I would rather have that in two parts. It is not always needed, in that there is a place to put the speakers, and I could leave the heavy stuff at home
One that springs to mind (for me) is audio monitors, where speakers are supposed to (in theory) be neutral in order to provide a good reference.
