  New techniques based on Exceptional Field Theory have recently allowed for
the calculation of the Kaluza-Klein spectra of certain AdS$_4$ solutions of
$D=11$ and massive IIA supergravity. These are the solutions that consistently
uplift on $S^7$ and $S^6$ from vacua of maximal four-dimensional supergravity
with SO(8) and ISO(7) gaugings. In this paper, we provide the complete
Kaluza-Klein spectrum of five such AdS$_4$ solutions, all of them ${\cal N}=1$.
These solutions preserve SO(3) and $\textrm{U}(1) \times \textrm{U}(1)$
internal symmetry in $D=11$, and U(1) (two of them) and no continuous symmetry
in type IIA. Together with previously discussed cases, our results exhaust the
Kaluza-Klein spectra of known supersymmetric AdS$_4$ solutions in $D=11$ and
type IIA in the relevant class.
