Has anyone compared these two tweeters ?
I am considering using a pair of either in combination with the new metal coned SB17NBAC35-8 woofers. I like the fact that the STCN is smaller, thereby minimising the spacing between the drivers, although tests on the ADC (by Troels Graveson) show very low distortion.

This site has test results for both: AudioGurman, just use a browser that can translate. He also tested the SB29RDNC-C000-4 which is also a small format tweeter. IMO all three are very good (I have used the two small format ones and have heard good things about the ADC besides Troels). Of the three the ADC should be able to cross over the lowest if that's a concern.
I`ve used about 28 SB26STCN so far, very good tweeter for the money with high consistency between units. The ADC has lower Fs and lower sensitivity, if you do a MTM with it, it can do without a resistor. The SB26STCN can be crossed as low as 1.85Khz with a 4th order slope although its best kept above 2Khz due to rising distortion.
I have made some design with SB26ADC-04, in my 3 Way monitor it was allmost impossible to pair it with rs125 (there was allways some problem with phase), so after all I have decided to pair it with SB15NBAC-08.
Overal very good, transparent tweeter, low distortion, can be crossed very low, but You must be carefull with top octave and correct it after some listening tests. The top octave with inproper crossover or amplifier can be to ''forward'' if You know what a mean.

Those cabinets are beautiful looking. It always amazes me how some people can make some beautiful looking cabinets - something I am not sure I can do.
Thanks for the kind words.
Building speakers is simple, just tell your wife that You are going to work, get up early and job done
Click on the link bellow, I wrote some tutorial in some strange language but there is a lot of pictures.

Those 1.5KHz and 5KHz 3dB bumps needs a bit of attention. Other than that, i'd say - job well done.
Have you found what causes that 3rd harmonic peak at 200Hz - bass or midrange ?

Your veneering execution is decent but the concept of beauty involves more than that. Stepped baffle of yours and the fact that the whole enclosure is of the same color, I mean the triplets, contributes to the overall appearance that is a bit less than optimal. Contrast helps very much.
I tend to disagree with your view about order of importance but that's another matter. To me they are both important but 3dB peak at 1.5KHz is fire to my ears, 5KHz just a little bit less. 3dB difference at frequencies where our hearing is quite sensitive can be a problem - at least for me.
I find more and more high quality Polish sites about diy hifi and testing/measuring loudspeakers. It's quite refreshing.
Dziękuję za to

I guess that's why I can't make good cabinets. I get up late everyday.
Knock knock... Who is there ?
SB26ADC
As I promised some conclusion about SB26ADC. Very nice driver for the money, transparent (with hell a lot of details) and smooth. Low distortion, can be crossed easy at about 2kHz 3rd order. The 3kHz artefact comes from my smallish baffle. In my previous 3way monitor it looked better.
The Worth of buying anyway..
I have pair it with SB15nbac-8 which is a very good also.
