You can only use so much magnetic strength before it becomes counter-productive. Qes values of less than 0.3 tend to choke off bass response, and even the original Alnico magnet D130 circa 1949 had a Qes of 0.27.
Neodymium magnet drivers have dominated the high end of pro-sound for over a decade. They aren't used to get lower Qes values than ceramic can provide, they're used to realize lighter weight and smaller magnet structures. They're also becoming popular in OEM auto sound drivers, for weight reduction. Most mainstream drivers still use ceramic, as it's cheaper than neo, mainly because the Chinese have a virtual monopoly and they're keeping the price up.
