[QUOTE="DNick454, post: 6350636, member: 600755"] Depends how much you flare the ends. You can only flare the PVC so much before it becomes too thin. If you're talking about simply using a roundover bit on the face of the box where the port is mounted, that's not "quite" an aero port. Rounding over the edges does give an "aero effect", but it's a smaller radius flare. True aero ports have a very large, and smooth, flare and also have pre-drilled holes for ease of mounting. Yes... they are quite expensive for what they are, but they are worth it IMO. If at all possible, get the real thing. You CAN however use regular PVC pipe and round the ends, just don't expect them to be [I]quite[/I] as efficient. 75 sq. in of port area should be ok thought for 9 cubes if you atleast flare both ends a little bit.
