I haven't seen anything like this in over a decade, and I don't have the patience to wait until I find and acquire something like this, IF it exists.

The problem is that it does not exist… Simply there are no customer demands on the market for such a product, not to mention it does look like shit. If it is not shiny and good looking there will be no sales, so… And the most ridicules thing is that it is unbelieveably cheap to produce!

Also, judging from the photos you have posted, you are presently settling for a more sedate presention and a narrower frequency range than I would want at this time.

I think the picture misleads you. The cone of my HF/UHF driver is only 55mm in diameter (it is deliberately ragged around its apex) and the voice coil has almost no inductance so it has almost no limitation of frequency response and because of the very low moving mass and strong motor it has 98dB efficiency. I have listened almost all of the tweeters that industry offers with all imaginary extended frequency responses but all of them sounded “closed in”. An exception of this list is Fostex T500a Mk2. A friend of mine bought a pair, so I had an opportunity to do some experiments:

The subjective feeling it gives is the harmonics goes to forever – very open sound, but also very very sharp. It is like someone shoot you in your face with needles, no matter how high you cross it and no matter if you have good SET and good electricity. In addition to that, it does not integrates tonally if you use paper midrange - no matter what you do, so you need very specific tweeter for your Reps driver. You may not believe me, but my small paper tweeter sound even more open – it allows you to hear very subtle nuances of the original acoustic space of recordings. T500a also present this effect, but to much lesser degree – as you look through very small audio window and actually it does not transports you at the original location where the music was played.

One year ago, I also used a ribbon tweeter, the I trashed it and now I don't even want to remember that time :-))
