I am trying to figure out the best box to run my pair of idmaxs ported, the spec sheets are just kinda confusing as to which is optimal they range from 2.0-2.7 I talked to Matt Borgardt and he sent me plans for a 2.3cu ft tuned to 28hz...I was thinking about 2.55 tuned to 32hz...what kind of difference would I see between the two?

Well I am just thinking about going ahead with that box...I have no other recommendations from anyone and getting plans from Matt who has extensive testing with the sub this thing should work...
