I'm in the process of building an inexpensive portable speaker and I had a couple questions as I haven't really had any experience with passive crossovers. This speaker will be a two way, and I'll obviously have a high pass on the tweeter but I don't want the woofer to run fullrange either.
1. Will using an inductor with a woofer similarly to how I would use a capacitor with a tweeter give me a 6 db/ octave slope? How would I go about calculating the inductor value? I know nothing about inductors.
2. With an inductor, could I also use a capacitor as a "bass blocker" for my woofer while also using the inductor as a low pass filter? Or will the two interfere?

Yes, the series inductor makes a low pass filter, instead of a high pass. f = L / (2 x Pi x R )
Yes, the two won't interfere much, if the low cutoff is much lower than the high cutoff, by say more than a factor of 10.
For example, 80Hz and 2kHz are far enough apart. Be sure to use a bipolar electrolytic capacitor.
