Hi,
I plan a cut off circa 3000 hz, center to center of 1 to 1.2 WL. No particular high spl needed so choice is big but the monney. Passive XO so resistor attenuation. I favor passive 12 dB slope but 18 dB still possible.
Thougths :
Sb26CAC
Monacor DN25
Seas 27 no Ferro
Sb26STAC
Peereless BC25TG35
Peereless NE25-VTS
Dayton ND25FW
Have you a preferred one among these you already tested or close in price ?
Thanks if you have experience with those.

My favorite budget tweeter is the Peerless DX20BF00-04. It's small (3/4" silk dome), cheap (< $15) and sounds great. Fs is 822 Hz and Xmax is 0.2 mm. I crossed it at 3 KHz, but used LR24 target slope. It took 4 parts (3rd order electrical plus pad resistor). I don't know if it could handle 12 dB target slopes.
Dayton ND25-FW

You can cross it lower if you would like.
Edit: just saw you are in Europe, so this might not be as affordable as in the US.

Hi CharlieLaub, this one is ok as I can find it local at Audiophonics so can be sourced cheap here, that is why it is on the above list.
I quite like the of axis behavior...seems almost perfect on the paper. Did you listened to it ? Anyone knows how looks the H3 and H5 for a 12db slope at 3000 Hz?

With a 3k crossover, I think you should consider the SB21SDC

It looks very easy to work with, great performance, nice price. There is a ring-radiator version also, the SB21RDC

Thanks hifijim,
I know you like the cac too. Had you the chance to listen to the SB21RDC or SDC over the sb26cac or the the sb26stac too ? I know only this last one and liked it in a refurb project.
The sb21sdc is also a nice catch, 1 cm diameter less front plate, better than the classic 104 mm wide tweeters. To be considered at a xover of 3000 hz for the c2c.

Oh for certain, the SB26CAC is extremely good. I have not listened to the SB21SDC or SB26STAC, I am only going by the specs and the various reviews.
SB29RDNC. The top end of this tweeter sounds wonderful. At least to me. Violins, flutes, piccolos, sound just like they are in the room with you. Very real with virtually no distortion.
Jeff Bagby chose it for his Piccolo design, and I don't think there is another tweeter that would be much better. Particularly at that price.

SB29 Neo Satori is better than standard version. It is more expensive yes. I think it has more detail in every way. Cymbals etc sound better. However to some it may be little to much ie less forgiving.
else SB29 neo with small faceplate is good.
I like Sb26STAC with augerpro WG. I could not believe how easy it was to dial in to flat in active crossover. Good thing with that combination of WG is that different variants of SB26 fit. Dispersion is as good as it gets.

If price is an issue a good alternative to the SB29RDNC is the SB26STCN. Same frame size and very similar sonic signature, especially if crossing over at 3 KHz. And about half the price as the SB29RDNC. Jeff used the SB26STCN in his Sopranos design.SB29RDNC. The top end of this tweeter sounds wonderful. At least to me.

A long time ago I sent Jeff an e-mail about using the SB29RDNC in the Sopranos instead of the SB26STCN. Here was his (typically gracious) response:
"If you want to use the SB29RDCN you are welcome to do so. To see the difference I switched out the SB29's in my Piccolos for the SB26 (yes, they do fit the exact same recess) and compared the response curves with the same crossover. To my surprise, their response curves were nearly identical except that the SB29RDCN was about 2-2.5dB more sensitive. Otherwise, the crossover summation and phase tracking was pretty much exactly the same. Part of the reason is because on an infinite baffle these are both fairly flat tweeters with a little lift at the top, and on the same baffle the diffraction response and its peak is the same too, so the same crossover slope and point work about the same. "
I like the SB acoustics SB26STCN. It only measures 72mm dia, has copper cap and neo motor, a vented former, no ferrofluid, handles a butt load of power, good xmax for crossing low and can be had for $35 or less. It measures better than some $100 soft domes.
I’ve been impressed with the price-to-performance ratio of the LaVoce TW131.00. I’ve been running one as low as 1.2kHz (4th order HPF) and it’s held up well. Usefully flat frequency response, too.

Thanks guys the sb26stcn is added to my short list with the DA25 horned from Peereledd above.
I also always wondered about the good Augerpro WG, however do not know how to re flat the curve with passive XO...

Hum they are clever at Lavoce, this little TN131 seems easy to fit https://www.toutlehautparleur.com/catalogsearch/result/?cat=0&q=Tn131
I gave up tye idea of the little OC Peereless because tye recess was very too much narrow for easy baffle fit.
Thanks chriss661 it seems to be ok for a 3 khz xo. Maybe weak rms handling if not in a standalone active amp.

Hi fellows. DX20 finally chosen. Will go with Dayton if I do not like it. The 66 mm diameter for a xo at 3k helped for the decision as the low Fs for a try with a 12 dB high pass. The apex of the dome is 3 mm beneath the front plate...helps a little too.
Thanks again.
Thanks again.
