Because you heard a difference in your usual subjective auditioning session? You aren't alone. Others have reported such findings too, including myself.
All good argues. This said, for an analog guy, not so complicated. We can adjust easily the (AUR) coils to fulfill precise enough filters.
On my side, i find digital is often a pain for DIYers (IE members of the poor guys hall of fame).

Speaker crossover filters are a extremely complicated issue, for many reasons, starting with speakers impedance, nonlinearities and ending with interactions of the FR with the speaker enclosure. Fine tuning a crossover filter is 99% a trial and error job, which is time consuming and expensive. The end result is almost always a compromise, not necessary an optimum one. A DSP is a much simpler, precise and cheaper approach.
Well, the day ( Eastern Dept.) started with how to kill best...at the end of the day we know the answer
🙄 😱
Something is simple when you know how to do-it. And a question of habit.
The secret is to flatten the impedances. And little other logical tips.
On my side i'm not able to design a DSP or a DAC from scratch.

Bill, No disagreement with DSP crossovers eventually when I am happy enough with a 4 (or more) channel dac. Maybe getting closer, have to see after awhile.
I believe you, it wasn't Bob's meaning though, well, stir it up in one sense 😉
C'mon, your fellow countrymen are kings of super-micro-engineered passive x-overs; think B&W, KEF, Spendor..., all of them. 🙂
That editing process wasn't involved in the experiments leading to their publication from 2000, that we were discussing about.

@billshurv,
I remember different experiments back in the old days (means ~1985 -1996) where passive multi-way systems were transformed into active ones.
If the frequency response of the passive version was the target for the activated system, the overall difference was remarkable small (no formal controlled listening test,though).
Same loudspeaker was used, passive crossovers and active electronics in seperate housings.
As it was a quite expensive sytem already in the passive version, parts for the passive crossovers were already carefully selected.
But, of course using digital equilization allows a lot more .....
