The JBL® GT5-1204BR provides superior performance compared to that of competing loaded enclosures, primarily because of its revolutionary Slipstream port, which provides lots of surface area outside the box so that the air stays stuck together – our engineers have named it the Adverse Pressure Gradient™. This gradual change from high pressure to low pressure eliminates the audible distortion called “whacking." Because the area of the port in the middle is much smaller than the mouth of the port, the port can be much shorter than a cylindrical port with a surface area the same as the Slipstream port's mouth, and it can fit into regular boxes.
