Default crossover component replacements

I can't seem to find a 6.8 ohm resistor for a parallel notch filter for a pair of cyburg needles I'm building. Is it better to go with a 6.5, or a 7 ohm resistor?

From a more theoretical standpoint, which value would have a higher damping factor?

The difference would be slight at best, the 6.5 would make the deeper notch. No way to know which would sound better without trying both, I think.

Any of these values can do the job, i'm not sure you hear some differences but test it!
From a technical view, the resistor is not a complex impedance and not change with the frequency.
The damping factor is the ratio between the output and the load of a given amp.
It show the ability of the amp to resist to transient return current that are created by the loudspeaker.
The loudspeaker is not a perfect load and the return to it's initial position after an electric excitation is not instantaneous.
The voice cone of the loudspeaker is elastic and make some rebound before to stop.
During these rebounds it creates current transient that return to the output of the amp.
The inductor, capacitor of the filter and the coil of the loudspeaker can affect these transient but never the resistor in the attenuator or in other filter.
