I understand that the resistance of the capacitors will decrease with frequency as the frequency moves above the corner frequency for each of the paralleled capacitors, but I'm talking about the added series resistance decreasing as each capacitor in turn begins to pass signal, since more resistors are being added to the circuit in parallel.

Compared to a circuit with three capacitors in parallel connected to one series resistor, a circuit with three capacitor-resistor pairs in parallel will end up with lower resistance as each capacitor begins to pass signal. Since I'm attempting to match the impedance of the RC network to the characteristic impedance of the speaker cable, wouldn't I be better off with the single resistor circuit? The perplexing part to me is that others have reported that the multiple RC parallel circuit sounds better, so I'm wondering if I'm missing something obvious in the theory.
