I will do that.  They suggest 1-1.5uF cap for use with a pair of their FE208 Sigma drivers.

What doesn't make sense to me is that the calculated crossover (3db down point) for that is 2k Hz and the tweeters are down 106dB at 2k Hz. (Edited, I had the roll off wrong)

Calculating at 0.1uF the crossover (again, 3dB down) is at 19,8943 Hz and flat at 198,430 Hz.  But I have tried 0.1uF and the tweeters functioned well.  They are easily audible. 

So the calculations don't seem to work as I expect.  It is confusing.

But forget the calculations, I'm trying to please my ears.

I never calculated it out. I just sort of bracketed it. I ended up at .33-.47uf, with no series resistance and yes it was fun pointing them to the rear...John

PS. I was looking at the pic from a while back and you know you need, at least 2 cats for proper room dampening 8)

I'm pretty happy with the KK 0.47uF@200V.  Not as special as the V-Cap TFTF 0.47, but much cheaper. 

I already have them.  The V-Caps are for my Eros and I really want to put them in there.

I'm in from the heat and doing some lazy listening, digital!

I put on Joni Mitchel's Night Ride Home and on the second cut there is a (I think I know the right name) talking drum that is 5 feet to the left of the left speaker.  I've had some images to the right of the right speaker, I think because of a reflection.  But this sound is solid and always in the same spot.  This is disconcerting in that it comes from behind the left wall and so much wider than anything else without the Carver C-9 making things come from everywhere.

I'm going to get the LP.  It is expensive!  About $40 delivered.  It seems it was not ever pressed in the US.

Told you guys these speakers are soundstage champs.
