These were very pleasant speakers in a system I had in the U.K. over 20 years ago! You are right, one can listen for hours without fatigue probably due to the treble driver, which was thought to be very sweet back then. As I recall, trumpet, horn and sax came over the midrange very realistically and the soft-roll base had plenty of punch. These speakers worked well for many types of music but I remember them best for the ability to work with close-in jazz. However these units, good as they were, were of a different technological time. Driver materials have improved so much that I think regardless of your cross-over tweaks you'll not improve greatly over the factory sound.
The treble unit, though sweet, rolled off beyond 18k as I remember and the midrange was a paper driver. You might want to rotate the base units 180 degrees, top to bottom, to help with the coil alignment. For me, I say accept them for what they are; a nice pair of older, cheaper speakers. lhlb
