The Satori Be tweeter is not at fault. It is a great driver.
The XO is either tuned too bright or something in your source components produces brightness. Accuphase typically is anything but bright.
Reflective room can make things worse. Diffraction control makes a small difference in tonality - in this case there is a nice big baffle, the problematic diffraction comes from midrange instead.
When you go about reducing tweeter output, you run the risk of messing up phases. Any component you add or modify changes phase, the reactive ones the most (caps and coils). The least interruptive in terms of phase is probably adding a parallel resistor with the driver (start with a high value, like 47 or 39 ohms).

 

I swapped to the fabric ring radiators, yes, and changed C1. I much preferred it this way.

 

I don’t think brightness is the perfect descriptor, though I can see why someone would say that.

I think a big part of it is trying to mate a beryllium tweeter with paper woofers (and then trying to put together upstream gear that synergizes with both). I’m sure the speaker as a whole would sound more cohesive if all the drivers were hard materials (like your high end Estelons) and the appropriate chain was built around all-Accutons or something.

 

This used to my belief for a long time as well. After messing around for a while this remains a component but does not determine much by itself. Xo, other driver characteristics and acoustics play at least similarly important part.

Fabric used for tweeters and paper used for mids are quite different materials, and are often thrown into same bucket. They 'sound' nothing alike on a same driver chassis.
Paper has been used for tw mebranes but it is not great for beyond 10k extension.
I think there is too much emphasis put into membrane matching to excuse inadequate xo designs. I can elaborate if anyone cares in science section.

A few people I have met simply dislike hard membrane sound - whatever divine effort is put in to ease it.

 

Yeah, would like to hear your thoughts on it! For me, in the 3WC-15 build, it was too much of a difference in leading edges and clarity/separation for me to figure out how to make it work. I tried amplification that worked better with the bass/mids or the tweeter, but never both.

Unfortunately, I've never been able to do extended listening sessions with any hard membrane. Diamond, Beryllium, Titanium etc. At best (with that creamy Satori Be tweeter), I get a brain fog and headache after 6-8 hours and, at worst, it sounds like daggers in my ears. Maybe I need to hear Estelons but I'm pretty sure it's not for me. It's not even something I think I hear. A lot of times it just feels like a difference in air pressure in my ears.

 

Thank you for your responses, my ignorance does not allow me to provide an opinion, but I read your discussions with interest.
It is actually more of a hardness rather than a shine.
Priidik, you know this tweeter, do you think as it is said in this thread that it requires a long break-in time?

 

@Adventech, you haven't found an amplification that suits the tweeter and the bass/midrange at the same time, only with the BE or with the fabric too?

 

I only had trouble with the Be tweeter. I never needed to think about integration after switching over to the ring radiator tweeter.
