Wow, I'd love to hear those!
Crossovers are not "all things evil" per se. Large coils on low-pass filters have insertion loss and cost a lot - lots of copper in the windings. Some folks prefer to minimize caps in the tweeter signal path (shunt caps a lesser evil than series ones, according to most).
Impedance bump and rise compensation and equalization for flatter response are usually good things. 90db SPL speakers with 90db SPL tweeters are a red flag - no baffle step compensation there, which can make a 2-way design sound very lean especially if it's out in the room where stand-mounts image best. (85/86db speakers are commonly the result of equalization and baffle step compensation...)
Some might abhor the use of transformers, but, they'd then need to abhor the output stage of a single ended tube amp!
In any case, I will definitely be looking into those specific speakers if only to better understand how they work. :-)
Cheers,
Presto
