mm100/104 bandpass

Systems

Does anyone\Polk audio recommend the mm104 for the bandpass enclosure listed on the site. I remember back in the day I heard a polk 10" db in the bandpass and it really jammed! Polk has specs for the 100 but only sealed for the 104, I know the specs are different but I like to see how my 4 10"s in that bandpass would sound. If so what are the exact specs for construction? the site only had ext dimensions, they didnt list how far up or down the sub or ports should sit. thanks
