I just got a Phoenix Gold XS84 8" 4-ohm woofer that I plan on using for a mid-bass. I'm not sure on how to build my crossover though. I had planned on having a bandpass filter between 100Hz and 250Hz. Does this sound about right? I used the narrow band pass filter calculator on this site and got values of 4.2mHy for the coil and 237.7microfarads for the capacitor. Do these valure sound right for a 1st order filter? Should I even be using a 1st order or a different one. Also where is the best place to buy the parts? Thanks in advance for any help!!

if you've got a few bucks to spare, check out crutchfield, they've got some nice plug-in type filters, high pass and low pass in various frequencies.
