Hmmm… I can’t comment on this. I never played with pipe and I do not know what works and what does not in there. I think to worry about high pass filtration via the foam inside the pipes is not what I would care. The foam in there to virtually evened the size of the enclosure and therefore to drive resonance frequency down. The resonance frequency itself does not say much and what does, in my view, is how and what the sound drivers produce. I know the drivers very well and I always appreciate in them softness with which the can play bass. It is a bit contra-intuitive and everyone is looking for had-ass bass and a lot of punch. It is very easy to get it from this drivers, just drive it with some kind of SS crap. To get the driver to play fast attack with gentle release is VERY hard. In my view those driver is they are properly loaded can produce very good result in the fast-attack -gentle-release department.  The amplification just need to be right and the loading need to be very sensible. If I were you I would male at this point the pipe hollow and empty (juts a smalls layer perhaps) and would think about the specifics of  damping by filler after the LF amp will be in place.
