Scanspeak D6600

Okay, I used the D3004/6600 in a 3-way active setup and tried everything that I could to like this tweeter (because it's highly regarded by others and expensive) but over a year or so I just learned to hate it. I was relieved when I sold them.
Later I heard the D2904/7100 in a commercial speaker (Stenheim Alumine Three) and the irritating character (for me) of the 6600 waved back at me in them.
Sorry for the fans, but that's my opinion about them.
But on a positive side, there are worse tweeters out there than these two (IMO).

thank you very much for your review, muach appreciated.
What didn't you like about the D6600?, in sound i mean.
 
Thank you,
Honestly I also noticed this with the D6600.
Now I have my eyes on the SATORI TW29DN-B but before spending money I would like someone's impressions if you have tried it...
Let's say that the two candidates are the scan speak D7100 and the satori TW29DN-B
I'm very undecided
 
The 66000 is a great tweeter! I find that the 71000 can be crossed a little lower and has good horizontal dispersion. But, not to the point where I’d change out a 66000 for a 71000. You’d have to change the crossover too; not a drop-in replacement.
Before changing out the tweeter, I’d exhaust all the other possibilities - exchanging the series tweeter cap, attenuation resistor, or adding a 0.01uF bypass cap. There’s also a difference between MOX and M-Resist resistors.
I use the 66000 in a 13” Scan-Speak 3-way, series-fed mid/tweeter crossover, and parallel-fed woofer. The results are amazing! I use a Mundorf Silver Oil Cap on the tweeter - lush, extended, and transparent at the same time.

6600 and 7100: excellent silk domes, if used right they sound smooth airy and with the sparkle. They can sound also hissing or sibilant, as they have too muchaenergy around 6000Hz. In that case I used RLC to suppress that area ~1-2dB, the sound got cleaner and more smooth and pleasant.
TW29TXN: I used this one in Jantzen WG, I somehow did not get too excited by the sound of this tweeter, it was too dry, the same impression I had from mw16tx, like the sounds were too fast and short, lacking the naturalness.
TW29BN: excellent. Less forward sounding then T34B and T25B, smoother, softer character, detailed and light sound with the body. Very well balanced.
9800: great alu tweeter, I liked it better then TXN
SB26ADC: almost as good as 9800

TW29BN would be my choice.

All mentined tweeters and lot of others I tried did not sound too dry. All of them have very low distortion.
When it comes to the discussion of the sound characters of the drivers, the essential aspect is actual listening experience. Attributing certain sound character to the distortion components without listening experience is academic discussion, considering all mentined drivers have excellent low levels of distortion.

thank you very much for your reply.
between 6600 and 7100 what differences in sound do you have verified ?
do you have tried satori TW29DN ?
 
Regarding 6600 and 7100, I used 7100 in one of my earlier project, and just once. 6600 later, in 3-4 projects. It is therefore hard to describe the differences, but based on my perception and recollection, I would go with 7100, and I plan to try this tweeter again. I think this Revelator has better chamber, somewhat smoother sound.

TW29RN, DN: yes I tried both, very good tweeters for the price, easy to use and make crossover for, easy to listen, they sound smooth and maybe a bit laid back, not that shiny as 6600.

Generally, each tweeter is different and each requires different approach to get sounding right. RN and DN profit from lifted top end, other they sound too calm. 6600 on the other hand requires flat top end, and ~6000Hz correction (actually I did the same for Discovery limited edition dome recently as well). Surrounding baffle dictates the off axis behavior a lot.

thanks for your kind response.
between the 7100 and tw29dn, which do you think is the more complete tweeter? Which one is less compressed and has more imaging?

you say that the DN is not as shiny as the 6600 but does this make the 6600 a bit annoying and too detailed in some cases for example for the muted trumpet?
that is, the DN has a deeper scene than the 6600/7100?

Is the DN qualitatively lower than the 7100?, you say 7100 is excellent while dn is good,
I'm very sorry for all these questions and if i misunderstood something
 
6600 and 7100, I percieve these as harder to work with compared to satoris in terms of making it sound good, balanced and not annoying. Similarly to t34b and t25b they sound very open and detailed, but also strong, they have energy. It might be percieved as good at the first moment, but also little annoying after a while, so it requires delicate crossover work to get trebles balance right.

Satoris RN, DN, BN on the other hand were easy, they are more relaxed. TXN was the exception. It sounded too dry, I did not like it at the first moment and it took me some time tuning the crossover.

They all have same flange diameter, so to find what tweeter sounds best for you you will need to try more tweeters.
 
I have 6600s in my studio mid-field monitors, with Seas W18NX midwoofers, and I've also used them in another 2-way I built for a friend with Volt BM220.8 midwoofers. My experience is that you absolutely have to have an RLC trap in parallel to flatten the impedance peak or they sound "papery" no matter how high or how steep you cross them over (within reason, never tried them above 2.5kHz or so and never in a 3-way). Otherwise to me they are pretty much as good as it gets for a 1" soft dome tweeter and they take high SPLs like no other I've tried.

Cheers,
