I am currently running a pair of Jeff Bagby's "Kairos" stand mount speakers (slightly modified), using the great SB Acoustics ring radiator tweeter, and 6" mid.
They are quite good, and image amazingly well. At least for now, I am very happy with them.
In the long run, I want to build Jeff's 10" woofer modules, which is not a subwoofer, but designed to basically turn the Kairos into a true 3 way system. The Kairos sit on top of the woofer modules, kind of like a WATT/Puppy.
At the present, I am running a very good powered sub, but the Kairos are running full range. What I want to do in the mean time, is to filter the low bass out of the Kairos, using an inline passive crossover.
My question is, when calculating the value of the capacitor, I am using the input impedance of the amp, which is 50K ohms. Calculated at 100 hz, this is giving me a cap value of .032 micro farads.
Does this sound correct? And are there any audio quality caps at this value?
Thanks!

When I first went to Parts Express, Meniscus, and Madisound, I couldn't find caps of this value. That's why I started questioning my calculations. I was wondering why wouldn't the leaders in passive crossover parts sales have this value?
But when I broadened my search, I found plenty of audio quality caps of this value.
Well, not in the traditional sense.
A "crossover part" would typically be a speaker-level component, rated for 250V, and in the range of 0.1uF-100uF for caps. 0.22ohm-50ohm for resistors, 0.05mH-10mH for inductors.
It shouldn't be surprising, then, that a component intended for line-level use falls out of that range of values.

Something like this should do the job
