Can you please explain that briefly ? Capacitors inherently have a current vs voltage phase shift. In a band pass network, there may be no phase shift, but then, a band pass network has a coil(s) and capacitor(s).
Nothing to explain, phase shift only occurs in the roll-off region, proper design practice will render the point moot.

I'll be using the Duelund Alexander in coupling duties, got to order next week.
Have read nothing but good things about these 🙂

Duelund Coherent Audio are the best.
CAST means 600V rating for tubes applications other users can go with normal ones 100V rating.

No...
CAST means they caps are 'casted'...
You can have 100/200V CAST for XO application and 630V CAST for circuit...
Thanks.

Well, i was a little worried that diverting some car repair $$$ to the purchase of Alexander caps would back fire on me...
Have them in my amp, and oh! boy! was i ever wrong 😀
If they are this good out of the box (on box, just a figure of speech), I can't wait till i get a couple of hundred hours on them
OK about 80 hours on them and they have opened up some, everything about the sound is just correct, instruments and voices have never sounded so much like the real thing, rock solid sound stage... and again just presented correctly 🙂
I had Mundorf silver and oil, and then a Chinese NOS Mil' spec Film & Oil that had a surprisingly captivating quality.
The Duelunds are better than both to my ears in my system, the presentation is just correct in tones, dynamics, transparency and sound staging.
Compared to the Mundorf's, the Mundorf's sound artificial.

Yes the Mundorf caps can sound sterile at times..Is this lack of colouration or just something is missing in the sound that should be there?
They don't give warmth to the sound..then again if you listen to a brass band in a park it has a warm sound..its not brash..Analytical comes to mind...Its interesting to hear the smear that standard caps add to the sound..compared even to the "cheaper" obbligatos..

I have Obbligato Gold in my crossovers, very good cap for the $$$.
My next objective is VSF Duelunds for the crossovers, but that's going to require selling one used/abused Kidney 🙂

has anyone of you guys tried the Jupiter VT Flat stacks beeswax caps in speaker crossovers?
used to have Supreme silver in oil on AG Trios, but have built new TAD based HF horns and need some input....

The silver/oil and silver/golds are only metallised foil caps. I don't like them - I think you need film/foil to get proper body in the mids and bass - ie. tone.
They have excellent treble refinement, but that's about it .
The cheaper zinc foil /polyprop are much better to my ears ( I liked the older Audyn KP-SN a lot but the treble was a bit bright ) .
My other favourites are Rel PCU (copper/polyprop) at phono and pre-amp levels, and Jensen copper foil PIO in power amps, as long as you have 15mA or more to drive them - otherwise they can sound dull .
This is my current take, after 13 years of messing about and a lot of disappointments ;o)
Hope this is useful

Oooh ! I don't know for sure , Leif .
My own ongoing 4-way horn system wil use crossovers mostly in in the multi-channel amp ;o)
But I would try the Jupiter flat stack caps if you can afford them , they sound interesting . I like PIO caps at higher signal/current levels, and the Jupiter are paper/wax so maybe similar .
It may be a case that you find silver-golds are good for the HF , but the Jupiter caps are better for mids and bass .

ok thxs
my thoughts too
probably try Jupiter FT then
if good I´ll try to battery-charge them ala Jbl
