Best for Classic/Progressive Rock and Blues

Used Wharfedale Lintons.

The original xover is part of the magic of those models. They are not designed for inductors like the Gravesen design. The way the drivers overlap in frequency ranges above 1500hz is key to their powerful sound. I still enjoy mine.

It would be the same speaker that is best on classical, jazz and any other form of music that you did not mention.

The JBL line is different. The woofers are descendants of the original D130 woofer used in the early JBL HiFi speakers in the 1950s. This speaker, and its many variations, also became the dominant speakers in electric guitar amps in the 60s that created the rock guitar sound. This led JBL to use similar drivers in their early studio monitors like the 4310 and 4311 that were designed for the higher SPL demanded by rock artists and producers. So those monitors and the consumer versions that followed all use woofers that reproduce electric guitars particularly well.  

That being said, JBL speakers are also great for classical, jazz, and any other form of music, as in your original premise. Audiophiles tend to avoid them because of their association with rock, to their detriment. I've seen all the "Junk But Loud" jokes but I smile because it keeps the price down on resales.
