I have been thinkin about a PR design for a little while, but they are definitely not as popular as either sealed or ported. There's not too many PR's out there. The VMP's look nice, but expensive! And I haven't seen any others with any kind of decent specs as those.
Anyway, how did you figure out box dimensions? What kind oof internal space did you use, as compared to what was suggested or required for those 8's in a ported box? From what I have seen, a PR box would be almost the exact same internal volume, and it's only smaller because you don't need to add the dimensions of the port, correct?
But your box looks awesome! Kudos on that.
