I haven't found that to be the case with the actives.
For example, the track below is hitting peaks of 101 dBC at my MLP with my dual 500s off. I have my actives set to full band.
With dual 500 support from 80Hz and below, it's hitting 104.5 dBC.
My MLP is 14 feet away from actives and subs. For reference, my Onk is at -5.

P.S. As a reminder, I don't have lab instruments here for my measurements.
