In this paper, we provide a concrete construction of Furstenberg entropy values of τ-boundaries of the group Z{equation presented} by choosing an appropriate random walk τ. We show that the boundary entropy spectrum can be realized as the subsum-set for any given finite sequence of positive numbers.
