Default notch calculator formula?

I've noticed that using the Lalena parallel notch filter calculator, which uses the same formulae as the DIY Subwoofer site,
R always comes up as 2.65 ohms, no matter what value of attenuation you input...????

(I'm going to use a pot anyway)

EnABL & phase plugs might not be a bad idea either
