In the present work the problem of coupled disordered quantum wells is addressed in a random matrix theory framework. The quantum wells are short repulsive binary alloys embeded by ordered barriers and show well defined quantized levels as a consequence of spatial confinement. Finite disordered superlattices may show both diffusive-like and localized minibands. Three different level repulsion suppression mechanisms are discussed by analysing the evolution of nearest-level-spacing distribution function within each superlattice miniband. The present numerical results show a motional narrowing effect, which is in fact a consequence of the random matrix theory.
