What you're seeing are breakup modes. They make the curve rise like that, but they actually measure pretty consistently. It's not a choppy curve, it's a steady rise. That helps midhorns with these drivers have useable response above 1kHz. Without that response curve shape, you wouldn't have much output up high.
