Naw, it's just that Ken and I are both fluent in nerdspeak.
This whole question may become irrelevant because I may just go with a sealed box for now (smaller and simpler!). The things of concern are: box size, construction simplicity, venting (getting the speaker output into the cabin, which may be a concern based on how I package it), low-frequency roll-off and transient response.
I know a sealed box is better at transient response, but I don't really know if transient response matters to me. The low-frequency roll-off is something I think I care about, and all the online calculators I could find showed a much improved low-frequency extension using bandpass, but again, I don't know if I'll care. Using my existing driver, the rolloff was only at -9dB at 20Hz, which was a lot better than the sealed box response curve. Up top, I'd be crossing everything over at 80Hz (head unit offers this, or 125Hz), and the front speakers I'm installing are good down to 100Hz, so the bandpass's much quicker rolloff up high wasn't a concern.
I can whip together a quick sealed box in an evening and then try it to see if it'll work where I want to put it. If I don't like it, I may pursue the bandpass box.
Oh, and Ken, I'll shoot you an email.
