@ryanosaur Nice!
Pro tip: The tweeter is held in place by these clips, so if you are going to fasten the wires with spades, it might be a good idea to hold these in place when you attach them. Because if you push too hard the tweeter will pop out.

Can someone please try measurements with an open-cell foam (or light felt) ring placed over the transition between tweeter surround and woofer voice coil? Basically thinking that some direct attenuation of diffraction from there might help clean up the response a bit. I'm not sure what thickness nor height above that area is appropriate though.
Whew! I was wondering if it was meant to be a proprietary connector and if I should futz with it…@ryanosaur Nice!

Good looking out Thorbjørn!
Question, since you brought it up… what happens if one happens to pop the tweeter out? Is it a simple matter of sliding it back in or does the entire world just disappear in a singularity?
(Or any other of myriad outcomes between “oops” and erasing all of humanity from the universe?)

I would imagine your continent might evaporate, but probably not the entire planet.
It's a matter of just pushing it back in.
But the clips don't feel extremely durable, it feels like they don't fit as tight if you pop it out and then in again. The only reason to pop it out would likely be to replace with a new tweeter (with new clips), so it's not designed to be popped in and out I think. I like the solution in the 8" coax much better where the compression driver is screwed in place.Is the tweeter in the back cap of the driver?I would imagine your continent might evaporate, but probably not the entire planet.

Thanks for the pics! See, now you have me wondering if its possible to start rolling tweeters...

Some companies do KS Digital and Dynamikks from Germany, for example.

I also do this often.
Here is a B&C 8 inch coax supported by an 18 inch subwoofer.

A few other projects got ahead of it in my queue and my measurement rig has been sidelined for a while as well. I just put the speaker in storage. Helping some other members with speakers projects and a finished pair of Directivas is a higher priority. I just finished a 2 channel NCx500 amp and am integrating my Thiels into my home theater. The Sica may see duty as a center channel but space is limited for it and so may just stay stored.
I am prepping for downsizing and sale of our current home so, unless the Sica center channel application happens, not likely to do much with it in the foreseeable future.
How'd it go with these?

I can understand shifting priorities, countless projects with limited time and energy.
I'm in the ideation phase of a project using the Sica 5.5 or 6.5, and Faital Pro 10RS430. Likely to be heavily inspired bith Scott Hinson's Triaxial design. Tweeter to mid with a passive crossover, and going active with DSP between mid and woofer. And with regards to the active part, have you listened to the NCx500? What are your impressions?

The Hypex NCx500 is great. Is quiet and powerful. It replaced a Purifi EVAL1 that has been put on my Thiels now. Am using a MicroAudio SMPS and the amp is running cooler than my other Hypex amps. Have not spent any time doing critical listening or any blind testing but am very pleased.

Sadly, they make excellent door stops. My work took off and I haven’t had time to play. That and I’ve been dealing with some chronic back issues, which on top of work makes me feel like every day is a double.
I did get as far as some good looking models and building a list of stuff I’ll need, but no sawdust.
Ouch! Feel better.
