at 2,500Hz is not as bad as in the Eminence's plot.

the attenuation of the peak at 2,500Hz. A crossover
of 1,750Hz seems to be optimal where I can safely
avoid using a notch filter for the 2,500Hz peak.

Musical reproduction, the Synergy crossover is re-adjusted
for 1,750Hz (Fig 6). A Shelving filter is inserted
for the woofer to lower the vocals slightly. This
has the effect of boosting the Bass. The RX14 retains
the same EQ network as before.
