The Last Breakthrough in Speaker Technology

What was the last major breakthrough in speaker technology? You may interpret "major" in any way you like. If you think the dimpled ports on your B&W speakers revolutionized the way you listen to music, or your time and phase-aligned drivers brought it all together, it's all fair game!

Drivers with no suspension (spiderweb) but larger voice coil connected to big flat disk (instead dustcap).

According to reviews it improves speed and linearity making sound similar to electrostats but very dynamic.
6 1/2" midrange uses ferrofluid for damping.

Larryi - there are some speakers that use drivers with underhung motor. Underhung is not very common because it uses very large magnet, but gives much lower distortions (better linearity). Example of such speaker is Adagio from Acoustic Zen. Sometimes tweeters are underhung to deliver better linearity at large displacements - like Morel Supreme.

I don't know why most of maufacturers use overhung drivers - perhaps cost.
