they're most certainly not always louder. Ported or 6th order both CAN be louder, with enough work.
now by louder do you mean peak louder? example, most people say isobaric is not louder than running an single woofer in the same size box, BUT isobaric is LOUDER in the 20-30hz range. so when u say louder do u just mean the ported an 6th orders can get louder at higher frequencies, or louder period?
