From your equalizer settings, it is very clear that the woofer in the 604C has gone sloppier, I mean the mass-breakpoint has moved downward, and as a result the high-end response of the woofer has suffered badly. This clearly indicates a loss of gap-flux or weak magnets. The HF portion seems to be ok.
