Subwoofer Porting

Why I choose to build ported enclosures and why it's important to use flared ports for subwoofers

Adding a port to a subwoofer box allows a higher output to be achieved at lower frequencies. Special care is needed to ensure that the airflow in the port does not develop compression and audible turbulence, otherwise known as "chuffing". Proper selection of port diameter and the use of flares can tame this problem. This section brings together information about porting derived from a series of experiments and measurements, along with techniques for making your own DIY sub ports.
