We consider the sample of weakly active galaxies situated in the ``Local Universe'' with inferred accretion efficiencies from 10^–2 to 10^–7. We apply a model of spherically symmetrical Bondi accretion for given parameters (M_BH, T_∞, ρ_∞,) taken from observation. We calculate spectra emitted by the gas accreting onto its central objects using a Monte Carlo method including synchrotron and bremsstrahlung photons as seed photons. We then compare our results with observed nuclear X-ray luminosities L_X, nuc_ (0.3-10keV) for the sample. A model is also tested for different external medium parameters (ρ_∞ and T_∞) and different free parameters of the model. Our model is able to explain observed nuclear luminosities L_X under an assumption that half of the compression energy is transferred directly to the electrons.
