I just want to ask what parameters I have to take into account of making a stonehenge enclosure...
FWIW, acoustically, the theoretically optimal driver placement on acoustically small rectangular cabs is down from the inside top ~0.46233*height with the vent as close as practical, but there's so little difference no matter where the driver, vent is located that it's really a non issue except for how the room affects it, such as when the vent is on a different side from the driver.

Not sure what you're wanting to know other than what's on the drawing: http://www.lansingheritage.org/image...closures07.jpg
