Problem with boxes like JF60 is that when they're lying on their side, the horizontal coverage in the crossover region narrows drastically. In case of JF60 its from 110º of nominal coverage to something like 35º at 2kHz. If that frequency would be below 1k or over 4k it wouldn't be such a problem, but with these type of boxes it seems to always be around 2kHz.
