Best Capacitors for Crossovers


I am now in the tweaking stage of trying different caps in my crossovers for my DIY homemade 2 way. I presently have and will soon try a 5.6uf 800 vdc +/- 2% Jantzen Audio Silver Z-cap.

I see that Mundorf, V Cap get a lot of accolades, and the Dueland are quite pricey.

Does anyone have a favorite?

I am trying to cross over at about 4500HZ at 6db.

When rebuilding my Dynaudio S25,s I posted this question on DIY forum and Eric recommended I try the Murdoff MPK,s , I took his advice for the mids and for the tweeters I used the VCap TFTF and CUTFs along with replacing the sand resistors with Mills with great success.

Thank you Eric for the recommendation.


 

I have a pair of DIY loudspeakers with Dynaudio drivers. They were built in mid 80's. Recently my tweeter got fried and I finally managed to get a replacement. However, I think it would be good time to replace the capacitors. These boxes were custom built by a guy who is unfortunately no longer with us. I took out the crossover from one of the boxes, but I have hard time determining the values of two capacitors. I'm no electronic wiz, so if the value is not specifically stated in μF, I am not sure what they are. The only thing on one of them is:

MKT 1.60
10 K 160V-

It's a bigger thing, inch x inch x half an inch. I'd really appreciate any help.
I have devoted 1,000s of hours running in and listening to capacitors from all over the world most recently several are from very good to Excellent  the new Clarity Copper S.A. cap gets my nod for best balanced capacitor at a very reasonable price. For money's not that much more then Solen these are very well balanced with a slightly warm character.
Next would be the Obbiggato Gold cap  slightly warmer still a bit on The rich side very close to a Mundorf Supreme  for less money.
The Big shock to this final cap was a total shocker. Sizes only .33uf
To 3.3. The  Fostex, caps from Japan they are Copper foil, as well  
As Tin foil. Using their own formula dielectric. In my new Martin Logan 11--A they will let you know exactly what is not right 
I replaced stock with Clarity Csa and Mundorf Supreme 4.7,and 5.6
Caps put .33 fostex, on them, had Mundorf Silver oil bypass,
I only put the 3.3 on low voltage in my DHT preamp.
I know 2 others who use these. The are exceptional ,very natural 
With tons of air around the instruments Bass noticeably better then Any Mundorf.  I think these are magical with the clarity and or Mundorf Supreme I recommend 10% or better with the Fostex,
They can go toe to to with any cap the Duelund Cast is the Only 
Cap I have found that us slightly better.
I have heard these in several settings,and now my own preamp
And Loudspeakers the engineers from what I was told spent 2 years on these the combination of Copper and specific amount of Tin foil  totally hit a home run . No more expensive then a good Mundorf cap. It proved to me sometimes looking at a well kniwn name ,known for their Drivers was worth checking out.
It is too bad they are limited in sizes .madisound seems to be the only sourse.
Do you think these would be good as output caps in a preamp or coupling to output in an amp? 
Is there a capacitor that would give my speakers a little more bass?
I am using SGO Mundorf Classic Supreme which are very good on my ribbon tweeters but a liitle light on the mid/bass speaker. Crossover point is 2000hz.
