i have made sevral posts in the past few weeks and all have revieled very useful information......

it is a vented enclosure.....the vent being 3inches in diamater......
the port has to be farly long to tune the box to 25hz........

quote from
"Where should I put the ports?
Ports should be placed at least one diameter away from any adjacent walls. If this is not possible to do this, the tuning frequency for a given port length will be lower than that predicted by the equations, and this may adversely affect the results."
