I was playing around the filters and found this PEQ curve to compensate the high roll-off

Since I used all 5 bands on Room correction and only have the Treble (Band T/7) available which can go as high as 10khz, wondering if we can extend the treble range up to 16.5k? So we can you it for the compensation curve?

Thank you
