Yeah, I dunno. I don't really think either is any harder to build but maybe. Personally, I have no preference either way. I liked the spirals because they had smaller angles in each fold, but that probably doesn't matter at very low frequencies. The path length is an issue though, maybe that's a slight advantage for spirals in rectangular boxes. The "W" fold cabinet has to be deeper to get the same path length. I guess the same could be said of the "Z" fold too.
