Well 1.68 uF doesn't sound bad (so far) but I will experiment further.
Now get those Visatons into your main system and stop worrying about snubbers! 😀

I tried them, they do sound good.
But they are still 86db.😀
The Epos speakers are on another stratosphere, anyway.
Give them a good amplification and they trully sing.
Btw Nuuk, a pair of sensitive speakers can still be a difficult load.
Sensitivity just means they play loud.
But you need LOUD AND CLEAR, and that means an as flat as possible impedance across the frequencies, without big impedance dips and rises.
In the vast majority of the cases you need a good amp, with a stiff PSU.
If you praise tight, controlled bass and detail all around.
Otherwise you'll find yourself picking the music for your system and not the music you wanna hear.
I listen to almost all kinds of music, the system must cope with that.
I hear you loud and clear old friend (or should that be young friend?) 😀
BTW, I'm listening to a great CD right now - Bugge Wesseltoft - 'Film ing'. Have you heard of it? 😎
Nuuk said:
No, I don't know that.
I have a little revelation for you, a CD you must buy.
It's portuguese, in the same league in terms of composing and performing art excellence as Madredeus (although different), that you like so much.
Rodrigo Leão - "Cinema".
Just get it! 😉
Ciare with tweeter
hi,
some month ago i tried to add a B&C D32 tweeter to my ciares. i tried caps from 0.33 to 1 uF, attenuated the tweeters to the ciares spl until i could meassure a flat frequency response.
The sound: yes in some songs the hights seemed to be better, BUT: without the tweeter it sounded more homogenous, smoother, more natural.
Any of my friens, which listened to it preferred the ciares without tweeter.
I think the problem is, that the ciares play until 18khz. - perhaps you need to decrease the hights of ciare with 6db crossover, when you use a tweeter.
I dont know.

I'll pop down to our local Portuguese record shop and get a copy! 🙄
OK Carlos, I'll look out for that one. 😉
Is this something to do with having two point sources for the higher frequencies? I can relate to what you say from what I have listened to so far with the tweeters! 😉

The man is getting prizes all over the world... should not be too difficult to get.
If you can't get it, drop me a mail.😀
I tried doubling up the tweeters on the Goodmans 201 baffles with one tweeter firing backwards. I couldn't detect any difference so took them out. 😉
Hi. Has anybody considered or made a TL speaker using the Ciare 250? Is the driver appropriate for this application?
When you search for CH250 on diyaudio you find an aperiodic enclosure that is not bigger than a TL.
Searching for aperiodic enclosures myself I found somebody claiming that air filters for motors are aperiodic. I find this very promising. Use a plain, narrow baffle and mount the filter of a big diesel behind the Ciares. I would use the filter open back to get a nice dipole sound.
Nuuk said:
Do you have the tweeters close to the Ciares?
It can be problematic if you have nore than a few cm separating the two drivers.
My Visatons work fine with a small (super) tweeter, but there's only 1cm separating the two drivers.
The enclosures are not very perferct, I was on a slippery day.😀
Attachments
Yes, but with 10 and 12 inch drivers the centres can never be close (unless you mount the tweeter in front of the woofer)!

THIS link, posted by someone else, shows a picture of a commercial design using a Ciare250 in an aperiodic enclosure. The one with the white ring around the driver. Looks very interesting, especially for those of us with smaller houses who would struggle to prise in a pair of OBs 😉 Apparently it has a volume of 30 litres.

I´ve seen a similar development at the german VISATON forum. Putting the tweeter off center makes for a MUCH smoother radiation pattern than in the centre of the woofer cone.
BTW: the VISATON experiment moved the tweeter vertically instead of lateral.
