I'll make a follow-up after almost a year of living with the speakers. No change of opinion. I installed the crossovers inside the boxes with no apparent loss of clarity. In fact, the sound is a bit better, I assume because the xovers are now tied to the drivers without binding posts involved. I tied the inputs to one pair of posts since they're single-wired. I still find them very useful and enjoyable systems. If you prefer the top-end on the relaxed side, you might want to get some alternative resisters and try knocking back the tweeters a smidgen. Just a bit, depending on taste/system. But no faint-praise here - these are fine loudspeakers with the supplied enclosures. If you can improve on the kit cabinets, go for it!
