Are there any electrical measurements I can make on a tweeter to determine what would be a good candidate for a replacement? I'd also like some reccomendations of speaker design concepts for laypeople, like a book or website. I'v been searching around and all the sites I've seen seem to assume some basic knowledge. Thanks.

Fewer than 100 copys of Vance Dickason's Loudspeaker Design Cookbook, 6th edition, are on sale @ madisound.com for only $11 because the 7th edition is now in print. Also visit the more-specialized speaker-building forum @ madisound.com (most discussion here concerns commercial speakers rather than DIY). You may make frequency & impedance measurements to deduce a similar replacement or to design a new crossover circut for integrating another tweeter with the woofer.
...is Fs (resonant frequency) and sensitivity (dB/2.83VAC/1 meter).You want your crossover ca. at ca. 2 times Fs (if the XO's first order).
Stuff like dispersion and all that is rather more esoteric.
Well, if you're shooting for a drop-in replacement into an existing system, the impedance curve also matters in my opinion. Not just the nominal impedance, but also the frequency and magnitude of the impedance peak at the tweeter's resonance - which will have been taken into account in a well-designed crossover.
... not sure how tecnical/fastidious the original poster wanted to be.
For now I dont need to be microsurgeon precise. I love technical though :) Ya might scream if you knew what I was doing to my ears currently. Right now I just need to get what I have in better shape to tide me over for awhile. Info given is more than enough, thanks.
