bumping this back up....took the cover off and took some shots of the guts...is there anyway I can figure out the xover points, and what ohm drivers it likes by looking at the parts used?

The blue wire goes to to the woofer, the red wire goes to the tweeter, and ofcourse the others are the input wires.

Looks rather cheap for a highly regarded brand.

I was thinking that too. Nothing seems special about them at all. Atleast, they'll just be temporary (if I use them) until I go active.

Ever see a Dynaudio crossover?

...

I have no idea what that ADS crossover is for. The old 320i/is components & 200i plates had larger & more complex outboard crossovers. The 300i plates had the crossovers onboard. Later models were produced during the time when ADS was changing hands over to DEI. You can tell the difference when the ADS logo went from "ADS" to "a/d/s/". Chances are that this is really a crossover meant to be sold alone for people looking to add tweets/mids to whatever they already had and was not sold with speakers. I do not remember these things at all and it's a pretty good chance that it's designed for 4ohm speakers and not meant for the HUGE ADS soft domes or later plastic tweets.

I put a thread up on DIYMA and this is the response i got initially:

hard to tell from those pictures.
if it is a simple 6dB/oct filter then it is 4khz at 4ohm.

if it is a 12dB/oct filter then I would have to know the value of the inductor, but my guess would be 2500-3000hz.

more than likely the inductor is for the midbass driver and you have 6dB/oct filters.

It told him the guy that I got them from mentioned something about 2500 xover point...to which he responded...

ok, if he thought they were 2500hz x-over then they are 12dB/oct. 10uF cap with a .31 mH coil would calc out to about 2800hz.
if you can trace out the midbass output, does it go straight through? neg-in to neg-out and pos-in to pos-out?

but that cap is 18uF unless I'm looking at it incorrectly.... so now I'm confused...I think you're right about the 4 ohm thing though.
