Limits on the value of the spins of supermassive black holes (SMBH) in Seyfert-type active galactic nuclei (AGN) are calculated using two hybrid models for the generation of relativistic jets: the Meier model and a model of tandem Blandford-Znajek and Blandford-Payne processes. A comparison of our calculations with limits on the spin obtained by x-ray reflection spectroscopy shows that they are in...
