Questions about bandpass designs

[djsSHO]

Well, I've got the dual bandpass momo box almost complete. However, I cannot find 2 5" port tubes for the ported enclosure. Is there anywhere these can be had, or is there an alternative size to the 5". I have found 4" and 6", but no 5.

Any help would be greatly appreciated

Hoping to have some happy bassing soon,

hey dude....

well... common belief around the SPL circles is that you can use PVC pipe for ports... just cut it to length and caulk it at the spot where it comes through the speaker box wall... heavy duty pvc pipe can be had in 5 inch diameters... try home depot, lowes hardware, or even value home centers.
