High output AND high resonant frequency - how does this work?

I'm looking at these pickups, which seem like replications of Barden pickups - single coil sized dual-blade humbuckers that boast high output, high midrange, and VERY high resonant frequencies considering their output - 10 khz for the bridge and 7 khz for the neck!

Holy moley! 10 khz! That's higher than the cooled, underwound vintage '54 bridge pickup made by SD!

How exactly can a pickup be that bright and overwound at the same time? Do they have thick metal plates to add more brightness? Please enlighten me about this, as I am a pickup novice!

It's possible they're ceramic and highly scatterwound.

What does scatterwound mean?

And how is a ceramic magnet different from an alnico one in terms of its output?

Ceramic has more power and highs. Scatterwound means that the wire is not "perfectly" lined, and it has less resistance, so that the highs won't be cut off so much.

The 10k and 7k numbers for those pickups are for DC resistance and not resonant frequency. The pickups in that Ad are actually underwound compared to the lil59 for Tele or Strat.

While scatterwinding may effect resonant peak freqs is has little to no bearing on the DC resistance.
