I still think the squawker and tweeter are basically in parallel. I mean, you wanted to put 8 ohms across the tweeter as well, originally right?
I don't think tweeters impedance at 700hz is very relevant, as that first cap also sees the tweeters impedance at every frequency above 700hz as well, probably dipping down to 8 ohms or lower at some points, hopefully for an 8 ohm average at the tweeters normal operating range.... I know actual impedance is complex, but we use nominal impedances to calculate starting points for crossovers, don't we?
No, I still think the tweeters impedance in its normal operating range matters a good bit at that first cap.... I'll happily change my mind if you can set it out for me.....
I'm also beginning to think that a resistor isn't the way to go, for me. I calculated 180mw loss across the resistor at 1000mw input for my method, and my favorite amps only do 3500mw and 8000mw respectively. Now I'm trying to recalculate the first cap... I have some nifty vintage NYT/Westrex 1uf paper in oil caps lying around that would probably sound pretty good.....
All this is important, even from an experimenters standpoint, because you could fry a horn midrange by sending it too much bass, and raising the effective impedance seen by that first cap will lower the effective crossover point, yes?
It would be a bummer to fry a K-55-V....
Once again, I'll happily change my mind about anything if you can lay it out for me... I have no formal EE training, I do have experince in professional sound reinforcement (theatre and music) and building tube amps....
