The formalism is applied to loosely-bound $^{11}$Li and $^6$He nuclei within three-body cluster models ${\\rm {^9Li}}+n+n$ and $\\alpha+n+n$. The $J$-matrix formalism is used not only for the calculation of the three-body continuum spectrum wave functions but also for the calculation of the $S$-matrix poles associated with the $^{11}$Li and $^6$He ground states to improve the description of the binding energies and ground state properties.
