Yup!
Maybe I should pour a wee bit in my coffee too?

I just microwaved mine. Just to reheat it, though.

Call Starbucks, see if they deliver?

I said coffee, not charcoal-inna-cup.
Nah, I should just make more.

See? I knew that would get you motivated!

>>No, I don't think it changes the impedance. I know that someone has the technical answer, and I've seen it before, but I don't remember what it is right now.
The best way to think about it is that the woofers and mid/tweets are active in different frequency ranges and that the crossover makes them seem to have a very high impedence outside those ranges. At low frequencies you might have a 4 ohm woofer and a 200 ohm midrange, while in midrange frequencies the numbers would be reversed. At the crossover point both speakers would appear to have a higher than nominal impedence (say 8 ohms instead of 4) and in parallel that still gives you 4 ohm effective impedence.

I saw a post on another site suggesting that an active crossover is needed before the amps otherwise you are amplifying the complete signal through both amps before sending them through the speakers crossover circuitry loosing any potential gain. Basically you amplify the whole signal and then filter part of it out by passing it through the crossover?
