Strange graph readings.
I would expect to see an amplitude peak around 3 db's higher on that ported box line, around the 40-50hz region. Every single graph I have ever seen, shows a FLAT curve for a sealed box, with a drop-off starting around 50hz, and a slightly higher peak in db just above the tuning frequency for a ported enclosure. And why would anyone ever want to run a GIANT over-sized SEALED box ??? Why not save space and just do a ported box?
