What in particular would you expect the Purifis 10"s do that's better or different? Not that I'm in the market for a few thousand dollars for drivers, but... curiosity. 😉
For that matter, maybe the same question for the Bliesma T34?
They are vastly better drivers on all counts. The stock Flanagangsters have a competently designed but otherwise very ordinary set of drivers. The tweeter design is basically 40 years old.
Purifi and Bliesma have probably 1/10 the distortion and I’m guessing much higher resolution. Technically far superior.
The way I understand it, the Flanagansters sound remarkably good because you optimized several audio principles, e.g. large Sd, high efficiency drivers in OB have an inherent liveliness across a hugely important spectrum of frequency content, and then hand off to a dynamic tweeter, all with superior directivity. Extreme technical performance becomes much less critical as a result... sort of an audio Pareto principle. I highly respect and appreciate that achievement.
I get the technical superiority, but not to what degree that actually translates into a preferable listening experience. I've heard systems that apparently measured great, but were totally uninspiring to listen to. Not saying that would be the case here, but also not assuming that it'd crush anything else.

When you slash IM distortion by a factor of 10, a woofer is bound to sound better.
Purifi in particular has gotten to the bottom of the swamp, solving some of the most fundamental problems in speaker design (linearity of the magnetic circuit) and you don’t have to look far to find rave reviews. It’s not hype, it’s genuine superiority.
Most drivers have +/- 10% shift In inductance from one end of XMax to the other, and they’ve solved that, among other problems.

That's pretty cool that they've solved some of those technical challenges.
What they haven't solved is price accessibility (5-10x?), but I can always hope for trickledown over time. Technical excellence can have its price, and the question posed to you was indeed cost no object. For some, it isn't.
As a personal perspective, they're the most revolting looking line of drivers ever... one of the few I've ever laid eyes on that I'd have a massive preference for hiding them forever behind speaker grills. I understand form following function when appropriate. Here, form necessitates banishing them from sight! Sometimes technical excellence can be expressed beautifully; and apparently sometimes it dictates mutant geometry. 😏
Anyway, I really appreciate your focus on making very high-performing speakers accessible to non-1% audiophiles!

I just noticed that your XO doesn't show a tweeter on the back?
This pairing of drivers seems like it must be a remarkable bang for the buck! And very nicely executed, I might add.
What made your choose the XT25 over the TW29R-B? I like the former, but am curious about the latter.

Thanks for the note, dayneger.
I added the back tweeter later, same one as perrymarshall uses, with a similar crossover.
I chose the XT25 because of its performance with the waveguide, and I had them lying around. Plus, I wanted to practice crossover design.
I assume that the TW29R-B is better and certainly more sensitive.

Hi Perry,
just a short question if may: what's the volume ratio between the front tweeter and the rear ambience tweeter (or to put it simply, how loud is the rear tweeter)?
Many thanks in advance.
