    That is the kind of complex crossover required to get the most out of your moon rock needle in a googolplex system. God you guys are dense.

      See that weird looking thing? It’s the outboard crossover to end all outboard crossovers, and it belongs to the relatively slim Evolution Acoustics Exact Series Maestoso 3-way loudspeaker system ($18,900).

      OMG, I just saw the price. You can buy something competently engineered for that much money.

        "Highs were a touch bright"
        My guess is that they didn't use enough inductance...

          Or maybe because they didn't orient their inductors in 3 axes, only 2.

            A tweaker's dream, all that copper.

            Everyone assumes this stuff is actually connected.

            And don't forget...

              It's OK for a car stereo, but I wouldn't want it in my house.

                Going further down the rabbit hole I found this gem:

                Q. Why are the Evolution Acoustics loudspeakers not bi-wireable?

                A. Since all Evolution Acoustics loudspeakers utilize Constant Voltage Crossover Networks, there is only one continuous signal path connecting all of the drivers together in series, thus behaving like a single unified transducer. Conventional crossovers typically have the drivers connected in parallel with dividing networks for each individual driver, which can allow for bi-wire or bi-amplification. Constant Voltage Crossover Networks produce the cleanest and purest signal path possible, since there are no crossover parts in the path of the drivers. In addition, because there are no parts such as resistors, inductors, or capacitors in the direct signal path, there is no added dynamic suppression. Increased dynamics and purity are the main reasons to bi-wire or bi-amplification. Evolution Acoustics loudspeakers simply do not require this type of connection.

                Uh...ok. No parts in the signal path. Check. That makes that monster crossover even more mysterious.

Therefore, be patient, because when adequately broken in their performance is sublime.
                    After hundreds of hours you will decide these are the best cables you've ever heard because you spent so much money and people don't like to admit they got conned. We like to call it, "post-purchase rationalization," a handy cognitive bias in sales and marketing.

                      Dunno. Where else can you find massive external crossovers where none of the parts are in the signal path? These guys are light years ahead of us!

                        Someone messed up. You're supposed to use the sensitive man-bunned neck-bearded guy in photographs. You don't ask him to write your FAQs. And it's Portland. Their yogi probably designed spiritual connects between the crossover and the speakers to keep the signal pure.

                          So, my crossover mojo is at the caveman level...Here's my dumb question. Regardless of whatever magic is happening in that giant crossover thing, you have a single wire driving both the woofer array and tweeter in series with the same signal (right?). No crossover in the cabinet to filter highs and lows to the appropriate drivers. Both the woofer array and tweeter are seeing the same full range signal? What am I missing?

                          ..or did they sneak in a single $0.09 electrolytic cap on the tweeter that they're not telling you about ;)

                            Fluff-free translation: it's a series crossover.

                            Anyone using the phrase "not in the signal path" for any electrical components is lacking an understanding of electronics. All crossover components are in the signal path.

                              So...it's already bi-wired (or multi conductor wired) from the crossover to the speaker? Hard to tell from the shrink wrapped wire mess coming out of the crossover. Their narrative makes it sound like it's simply a two conductor wire.

                                Well, sort of. I think they were just too lazy to provide separate inputs to the drivers for bi-amping. Bi-wiring is a joke to start with.
