proac d2’s do not extend flat down to 30 hz... not even close... the stated specs list 30 hz response limit but without a +/- db indication...
if they in fact do 30 hz they have got to be minus 8-10 db down from 1 khz... so proper subwoofer augmentation will absolutely present a true full range response, and a pair of rels would be great for that purpose... larger ones if you have a large room
