I would use the Parametric EQ
In a parametric equalizer, each filter cuts or boosts a range of frequencies. Each filter has three controls:
frequency: the center of the frequency range to be cut or boosted
gain: the amount of boost or cut
Q: the "sharpness" of the boost or cut, with higher Q meaning a narrower filter
Parametric EQ thus allows a single filter to be very narrow or quite wide, and it is therefore very useful for correcting frequency response errors in a loudspeaker or reducing peaks caused by room modes. When implemented digitally, parametric filters can also take the shape of a "shelving" filter, which boost or cuts frequencies above or below the filter frequency.
