YES! But it's hard, you need some ginormous passive components. That's one reason the Power Cube https://www.audiograph.se is expensive. I was going to set up a 70 Hz capacitive and inductive load setup, maybe 45° phase angle. However that reviewing gig died and I changed what I was doing anyway so it never happened. I chose 70 Hz as not having common low harmonics with 60 Hz American mains frequencies.

Active Crossovers w/o dsp
We need to compare the distortion characteristics of an active crossover to a passive crossover in a speaker.
This would be a first or at least ground breaking in understanding how they compare.
Personally I think this is vital to know as these types of crossovers will still be used for a while. I've moved onto digital crossovers/DSP but still have a few speakers with passive and active crossovers and would love to know what my better option is between the two.

Using feedback and feed forward techniques using DSP you are guaranteed to be able to achieve lower distortion if done properly in an active speaker design. But that's not the same as simple active / DSP crossover.
I should have said electronic crossover. Yes, I agree DSP crossovers will definitely give you lower distortion. But what about say a passive internal crossover of a speaker vs a Marchand XM66 crossover with the same speaker?

Would love to see how these overpriced Wolf PC servers compare to a standard PC or Imac.

Since DDCs or reclockers are again entering the marketplace, I would like to see them put to the test.
I saw a couple of folks like the xkitz opamp based crossovers, and I believe they were tested to be very low distortion, but then a gent on diyaudio fb said it’s output can’t reach 2v on the negative rails. I believe he actually created a new PCB to solve that.
I would certainly like to see an opamp based crossover tested.
But the flexibility of dsp is hard to beat, and therefore will dominate the future?

Same here!
How about testing this headphone amp that has PEQ built in, it's from miniDSP:

Dayton Audio produces a very cheap line of DSP Amplifier boards. I'd be fascinated to know how far these units could be pushed. They're advertised for boomboxes and car audio use, but if they fit into hifi applications, it would be a welcome drop in the cost of active speaker development.

He has tested it. Seems not bad. Interesting that few has mentioned this device. Sounds interesting.

From a purely academic point of view - the Logitech Squeezebox Touch. Still plenty of them out there. Just how good is it?
Yes, I know it needs a server, but it's a classic and I feel it deserves a moment in the spotlight.

Capital idea. This incredible theme created by a contributor has breathed new life into my Squeezebox setup. It's a joy to use. https://github.com/CDrummond/lms-material

Looks like it could hold its own in comparison with a lot of the current crop of streamers.
