 VENT PIPE TABLE - for speaker box (port) vents                    

  by Russell Storey

 SPEAKER BOX VENT (PORTS) ROUND

• speaker box vent (ports)can be made from pvc pipe which are available in various diameters and wall thickness

• The pipes are normally used in the plumbing trade but make excellent ports(vents) for speaker boxes

• The mean outside pipe  outside diameter varies with different manufactures (brands) of pipe

• The mean inside  pipe  diameter varies with different manufactures (brands) of pipe

• When cutting the vent pipe hole in the speaker baffle  always measure the outside diameter of the pipe first

• Use a router or circular saw for hole cut out

• Fill the vent with wadding to reduce turbulence and achieve a higher roll of frequency and  less bass boom in bad room conditions 

• DWV(down water vent) has a thicker wall thickness than normal storm water pipe

• Use wood glue to secure pipe into the  baffle panel to achieve an  air tight seal

• Can flare the ends of the pipe with heat or house the pipe into the baffle with a router and flare the timber

SPEAKER BOX VENT (PORTS) RECTANGULAR

• Area of the rectangular vent is  calculated with (Height X Width) of the inside dimensions

• Can use wall of the box for the vent sides

• When cutting a rectangular vent  hole in the speaker baffle allow for the wall thickness usually the thickness of t he box material 

• Use a router or circular saw for hole cut outs

• Fill the vent with wadding to reduce turbulence and achieve a higher roll of frequency and  less bass boom in bad room conditions
