accuton C23 cut frequency?

[tomat]

Please help,how much the ideal cut frequency for accuton C23 tweeter. Thanks

[tomat]

sorry, C12 i mean,25mm ceramic tweeter. thanks for help

TOMAT,
What is your project?
This tweeter is very good for a first order xover.
It looks good to follow the sugestion. And it looks good for experimentation also, like a low xover point too, like 1K6 and up as a general rule (maybe not in a 1.order).

High efficiency, ferrofluid filled tweeter with 25 mm light weight concave ceramic dome. Perfect choice for 3-way systems or small, low-output 2-way designs. Very high resolution and very good dispersion up to 42 kHz. Low resonance frequency allows first order filtering and a crossover frequency as low as 2 kHz.

Do you mean:
(1) ACCUTON C²95-T6
http://www.accuton.de/e/data/product.../e_C95-T6.html
or;
(2) ACCUTON C²92-2x6

Do you have a closed enclosure? What size is your box?

I think high XO point with 1 order is a good idea.
Low XO is a bit too difficult for this driver.
C44 is used for low XO application more.

thanks,the exact is no 2,c92-2x6ohm,the enclosure is vented with internal volume 21L,as i calculate with win isd,now i'm try to invert tweeter polarity,still with 2nd order xo,the freq around 4 - 4.3khz,it's better,but still make my ear fatique
here is pic of my speaker

Thank you Foo,I will try that,probably around 6 or 7khz with 1st order

Hi,
You can test/use this xover.
You can ajust the L-Pad for your convenience.
For the tweeter resistor R1=3,5ohm, if you think you have to much wizz (@>10KHz) use a higher resistor (ex: R1=4,5ohm).
To adjust tweeter attenuation (shelving) use resistor R2. If you use a lower resistor than 7R you are going to have more attenuation (~1dB for a 6R0), or the opposite to make it more alive.

It's a (+/-) 2.2KHz, 83/84dB, 2.order xover.

(Note: this xover is for the 2 woofer coils in series)

Considering a few factors (this is a simulation) here is a new xover based on the same idea (now 86dB, xover at 2KHz). Now the key here (testing and patience), besides the adjusting of the L-Pad (new) like I said, is the 8,2uF cap. Let's say you need more power on the xover band at ~2K0Hz, then change it with a 10uF cap and output will go up about 1 or 2dB, only for the tweeter at 1,5K/4KHz band. Testing is essential. Report.

(Note: People that want to use clones can use VISATONS. Woofer AL 170 8 OHM and Ceramic Tweeter KE 25 SC 8 OHM. They will work fine with this setup. Make sure to give 2dB more attenuation on the tweeter. Make R1=~5,2ohm and R2=~7,6/8,2ohm. This setup is for 84dB)
