The recent discovery of the $D_{s0}(2590)^+$ meson by the LHCb Collaborationhas stimulated the analysis of meson-meson channels effects in the two-bodyquark-antiquark meson spectrum. This resonance, assigned to the radialexcitation of the pseudoscalar $D_s^+$ meson, has a mass much lower than thepredictions of naive quark models, which could indicate a non-negligible$D^{(*)}K^{(*)}$ coupling which reduces its mass. Based on the importance ofnearby meson-meson thresholds in the dynamics of P-wave $D_s$ mesons such asthe $D_{s0}^*(2317)^+$ and $D_{s1}(2460)^+$, in this work we perform acoupled-channels calculation including the $D^{(*)}K^{(*)}$, $D_s^{(*)}\omega$and $D_s^*\eta$ channels, and study the impact of incorporating those channelsin the mass of the bare $c\bar s$. The coupling between two and four-quarksectors is done by means of the $^3P_0$ mechanism, with all the parametersconstrained from previous studies of the heavy meson spectroscopy. The masses,widths and production line shapes of the resulting state are analyzed.
