Abstract: This paper addresses, for the first time, a key aspect of the phenomenology of Compact Symmetric Objects (CSOs) — the characteristics of their radio spectra. We present a radio-spectrum description of a complete sample of high luminosity CSOs (CSO-2s), which shows that they exhibit the textit{complete} range of spectral types, including flat-spectrum sources ($alpha ge -0.5$), steep-spectrum sources ($alpha -0.3$.arXiv:2408.13077v1 Announce Type: new
