Yes I agree. I’m just not sure what to get in all honesty lol. Could get nice Klipsch. Not sure what it takes to power those but anyways just an idea. Could probably sell these for 1000+ easily they are really nice. Amazing condition. Might recap them, give them some break in time and maybe sell. I just like the vintage look and neat to hear it how they heard it back in the 70s.
In olden times, the advice was to go to as many audio stores in your area that you could stand to visit, and listen to as many different speakers, and types of speakers (e.g., horns, domes, ribbons, whatever) as you could find, and then pick based on what you like that fit your budget and fit your space. But now that is harder to do than it was in the past. Still, if you can manage to do it, it would help you decide what you want in a speaker.
Of course, nothing these days looks like the old speakers, so if you want that look, one is left with looking at vintage speakers. There is, though, a model above the CS-99A, which most people forget about, because the number is smaller, and the speaker is bigger and heavier and therefore more trouble to ship: the CS-63DX. You can see various models in this brochure:

Notice, they have three lines of speakers in the catalog; the CS-63DX was the top of the CS line, and was the most expensive speaker in the catalog, though they were promoting the new R series at that time, which is why they are listed first. (The third series in that catalog is their Project line.)
The CS-63DX is better than the CS-99A. But it is still a vintage speaker, and sounds like a vintage speaker. It is a very reliable speaker, without foam that "rots" and other such issues that plague many old speakers.
