• In this paper we investigate the frequency spectra of dilute fluids (or fluidlike disordered materials) composed of particles with embedded harmonic oscillators, using a recently proposed working scheme based on systematic corrections to the mean spherical approximation. The tests are performed in the low density regime where linear approximations are known to fail badly. A detailed comparison with computer simulation results shows that use of the improved theory correctly reproduces the qualitative features of the low density spectrum, whereas at high densities the mean spherical approximation results are recovered.
