In a nonrelativistic constituent quark model we find a constraint on the
mixing angle of the strange axial-vector mesons, $35^o\stackrel{<}{\sim }
\theta _K\stackrel{<}{\sim }55^o,$ determined solely by two parameters: the
mass difference of the $a_1$ and $b_1$ mesons and the ratio of the constituent
quark masses.
