There are some very interesting moments with the not-so-expensive Sonicap Gen I caps, which I have described in the K&K thread. I will replace the 935s with these. I am willing to take the chance that the little .033 uF 1000V 950s in my unit...

Here is the link, though I have no idea whose words he is quoting:

The caps are $1000 per 630V/1uF. So, I wonder what those super expensive caps ...

It is nothing to do with Wisdom. It is my principle of application of “cost” as a common sense design tool. I do not bitch that Duelund caps are expensive. I just try to find a rational solution for using them that would embrace their price. My ...

"This topology was invented by Steen Duelund"Ah-hm, ring radiators where not invented or even re-invented by the Steen Duelund dude, just copied. JBL used the priciple 40 years prior to that in: 2402-2403-2404-2405 and Fostex have been using them al...

Another rushed post, thinking about Romy's "miles of wire" remark, germane to the giant Duelund caps.I have thought about this sort of stuff for some time, and I have come to the point where I tend to think of all parts as partly obstructive (sorry.....

So, the first DSET is still downstairs on the electronics bench and I am back to work for a while, but not too hard and not for too long (I hope). I've added all the filters and checked and tested and changed some more things and decided that it was...

Dan, it is funny that the Hovland is one of only a few caps I have specifically ruled out for crossovers.I do not like but merely settle for black Solens for larger values, mostly because I just don't like to solder together great wads of smalle...

Hello Marc Henry,I am curious as to why you picked the 4540 driver for HF. I have no experience with this unit but it is interesting since the design claims to be of the "ring-radiator" type. This topology was invented by Steen Duelund for use in reg...

What's the deal with all these expensive, small value caps? Are people paying this kind of money to bypass their cheaper couplers, or what?http://174.132.244.231/copper-teflon-capacitors.phpThis spiel contains a lot more "technical information" than...

[quote user="Paul S"] Does anyone know the voltage the big couping caps actually see? Yes, I should measure it, but I would rather avoid the drill of opening the amps, propping them up somehow and measuring if someone already knows the answer. Of co...

[quote user="Romy the Cat"]fiogf49gjkf0dI am observing an interesting and surprising fact – I am begging to like my active Marchand crossover. I did a number of modifications to it and it looks like the parts are broken-in now – it does sound very pl...
|

Righto then, I guess there is no reason not to try this, except that one of the original crossovers here is non-functioning (if I remember correctly), so if trialling in stereo I'll have to crossover in Melquiades. Should have the parts here to do t...

Referring to the threads a few month back:

I wonder if I need to play with the coupling cap between the first and second stage. Now I have my beloved ElectrocuCube 950. In my former version...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

[quote user="Romy the Cat"]As much as caps in speaker
crossovers makes deference, so do they make in coupling applications. In Milq
the cap is light duty as the amp never goes A2 and the cap is not change the
polarity, still the coupling caps do m...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

user="anthony"] Plenty
of thought has gone into the speaker cables largely because there are plenty of
them and I would prefer for them to be hidden completely from view. Five

[quote user="anthony"]Thanks for your
insight Romy. I can see your point about not needing to worry too much in
the DSET about coupling cap performance at higher frequencies but I would
imagine that the crossover filter caps are quite import at t...
