speaker boxes for rear ported speakers

hi all, i'm trying to design a new production suite and am considering fitting it with a 5.1 system made up of genelec 8040A's and a 7070 sub. ideally i would like to mount my monitors in speaker boxes but seeing as how these are rear ported i imagine that might cause some problems. has anyone had to deal with a similar situation? cheers. cobber.

Speaker boxes as in, soffit mounts/flush mounts, or something completely different? Steve
