Capacitors in series halves the capacitance. But I don't know about resonant frequency. Can you point me to some info? I had trouble finding what you were talking about on Google.

This article talks a bit about resonance frequency

The basic reason for the lowering of the resonant frequency is found on the following link.

The effect is shown on the following graph, see the last page in the pdf file

But if the point is well beyond the highest frequency out of the DAC that you want to attenuate it is ok.
