  Strange axial-vector kaons, $K_1$, and $f_1$ meson resonances are
investigated in the 4-flavor AdS/QCD model. Their underlying differential
configurational entropy is computed and the mass spectra of higher-excited
resonances, in both these mesonic families, are achieved and discussed. This
technique merges the 4-flavor AdS/QCD and experimental data regarding the mass
spectrum of $K_1$ and $f_1$ meson resonances that have been already detected
and reported in the Particle Data Group, also bringing forth a route to explore
physical features of the next generation of resonances in the $K_1$ and $f_1$
meson families.
