For example if the center frequency is 62.5Hz and you want to tame a nasty peak of 8dB at 58Hz can you move the band center frequency back to 58Hz.
The centre frequencies can be moved, but only in 1/3 octave intervals. So the choices you get are 31.3, 39.4, 49.6, 62.5, 78.7, 99.2, 125Hz etc. (doubling every 3 steps).
For 58 Hz you have to use 62.5Hz since that's the nearest. You'll still get some effect at 58Hz because even with the highest supported Q factor the filter is not that narrow, but this is far from ideal. You may want to look at separate sub EQ systems.
