According to JL the woofer needs 1.75^3 ported and 1.4 sealedIts supposted to be 1.5. And FYI if you don't understand dampening and how it affects frequency response I'll be glad to help.. The stiffness on those drivers really aren't ideal for vented alignments. Although they do have ways around it there just not ideal..
You have to have a certain stiffness to mass ratio for vented alignments to obtain critical damping. This causes a underdamped response. Making the enclosure smaller lowers it's compliance to compensate for the softer suspensions used.
The higher qe also means that it has a wider bandwidth electrically wherein the driver resonates and this naturally means easier low frequency reproduction visit great sensivity..
And I'm talking in the sub bandwidth we
Here in the human perception is ruffle 20hz to 100hz typically closed to 30-70hz cause most people know next to nothing about speakers
