Need some help in making the decision on swapping out a cap in my new SEAS Thor xovers.
Spoke with madisound, they had no answer to my Q.
Here is the schematic for the Thors, along with some pics of the new xovers

OK here is my Q
The C2 cap, we havea M EVO SGO 8.2uf
and in the C3 we have a M Supreme SGO 10uf + EVO SGO 8.2uf
I am considering adding a
Supreme EVO SGO 8.2uf either in the
C2
OR
C3.
My Q is , which cap has more influence in the pathway.
My hunch is the C2 as the better choice employing the SESGO..
As you know theis cap is $220, so I am looking to make <<best bang for the buck>> Besides the SESGO are quite large and may have issues trying to wedge it between the 10uf and 2.2uf,,whereas the C2 spot has plenty of room to bring in that quite large cap.
The C2 is like the entry way for the initial frequences comming from the amp..
My guess it should go in that position.
But looking for more expert opinions.
and yes, the SESGO does have sonic gains vs the little brother = the EVO SGO.
All comments welcomed.

It's a parallel circuit with an alternating current. You do realise what that means, yes? There is no 'entry' or an 'exit' for an 'initial signal'. The signal moves back and forth. Hence the name 'alternating'. C2 is not 'before' or 'after' C3. That isn't how AC signals or circuits work. Let me give you an illustration. Hold L3 static. Place C2 and C3 in the supposed 'negative' leg. The circuit will perform in exactly the same way. As in exactly.

Thanks Scott, I'll study up on this info, At least its more than Madisound was willing to give up.
So its like a circular /closed circuit,,, all caps are equal,
So based on what you gave me, either in the C2 or C3, results will be the same..= better in the C2 as there is plenty of space to bring in such a large cap.
Whereas in the C3, my tech will have to lodge it up above, etc,, = really not doable, he's going to say.
WOW 1st response cleared things up nicely.
Thanks again.

Not a problem. It's boring I know, but it's how AC circuits work. As it happens a few manufacturers chuck the series components into the 'negative' leg for the sake of being different, but they work the same way. A few years back, when I ran a small business with my mate Colin, I did just that with a particular design to illustrate this point. Bit of fun.
Really helpful Scott.
OK since i have your skills/advice at hand.
can you help me out on deciding caps for a near future project,, The Seas <,Bifrost>> design.
I plan to have madisound get in touch with their danish xover designer, as i plan to swap out the Nextel W18 for a Nextel W22.
so will be a
Cresendo + W22 Nextel.
Here's the Q.
The midwoofer takesa 10uf.
Would it be <,less practical>> to place a Supreme EVO SGO in midwoofer vs the better choice of employing using a Supreme EVO Aluminum((which goes for far less than 1/2 the price of the SESGO)
My hunch is that the silver is prefered in the high freqencies, and so adding silver in the cap for midwoofer fq's, will not make much IF any impact on the upper range of the W22.
Follow?
BIFROST
Here is the cap i think you will agree is the <,ideal>> cap for the midwoofer at $70 vs the SESGO @ $220

OK, a couple of thoughts, for whatever they're worth at this stage:
Firstly, what you are talking about is a complete new speaker design from scratch, since it will need a different enclosure and different crossover to the Bifrost. That's fine in itself, no worries on that score, but you probably won't end up with the same network topology as the drivers have rather different requirements, so I would hang fire considering components until you actually know what you're going to end up with.
Beyond that -to be honest, I'm not personally into expensive components per se, so others will be better placed to comment on that when the time comes. I struggle to hear differences between capacitors of the same general type and value in a passive loudspeaker crossover, although I do sometimes hear a few between capacitors of very different type / construction. My general advice in these cases (which I acknowledge isn't necessarily the most entertaining, but usually reaps rewards), is that you focus on the design and system setup first, and then, if you wish, turn to the components after those have been addressed.
