Port placement in a sub box?

Are your subs in one, 1.75 cf box or are they in thier own 1.75 cf box? Your statement contradicts itself. If your subs are in one 1.75 cf box then don't port it ( not big enough ) If they are in their own 1.75 cf box then yes port it but don't use that p.o.s. port from sonic. The specs for that sub state that you need a port that is 10" deep x 4" wide. You must use a port that is exactly that or it will sound like **** . Just build your own port square port out of 1/2 mdf and cut a hole in the box and pin nail and glue it in. Make sure to bevel the edges to reduce air turbulance.
