The main result of the paper is to prove that the classical joint spectra of an \(n\)-tuple of commuting operators \((T_ 1,\dots,T_ n)\) on a Banach space, as the Taylor spectrum, the Harte spectrum and some other spectroids, the geometrical spectral radius is the same and depends only on the commuting \(n\)-tuple of operators \((T_ 1,\dots,T_ n)\).
