Update: I built the dual 2.5kHz high-pass filter using a pair of 330pF ceramic disks. However, before I could use it, I came to the realization that I'd designed it for the wrong crossover frequency. As I've mentioned before, the Paradigm Studio Monitors are tri-ampable, and the crossover has two frequencies, 275Hz and 2.5kHz. Shortly after building the filter, I realized that I should've designed it for the 275Hz frequency instead!
I re-ran my calculations, and the proper capacitor for a 275Hz filter would be 1,157pF. Returning to the local electronics store, the closest I could find was 1500pF. Running this through the formula, this capacitor value would give me a filter for 212Hz, which should be a decent safety floor. What do you think?
My next question is, how would I test that this filter does what it's supposed to? The closest I have to a spectrum analyzer is the one in my BSR EQ-3000 equalizer. Would this be suitable? If so, where should I connect it? Finally, how would I use it to test the filter? I know that the EQ-3000 has a built-in white noise generator, but I don't know how it'd come into play if, say, I have the EQ wired between the filter and the Mark IIIs. Thanks in advance!
