Looking to put some bump in your trunk? JBL's preloaded subwoofer enclosures will put you up front and center for the ultimate live performance. 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.

This offers better control at the excursion limits than the linear spider commonly used by competitors. This progressive spider reduces distortion at high output levels.
These provide additional cooling to the motor structure, resulting in an increase in the subwoofers’ thermal power-handling capability.
The double-flared shape of the oversized port is precisely calculated, efficiently eliminating port noise. Even at high SPL, airflow through the port will remain uniform, offering better low-frequency extension and woofer protection.
The vented polepieces and motor structure provide additional cooling. In combination with the rubber-coated tinsel leads, this results in much better long-term reliability.
The increased magnetic flux results in higher efficiency and better woofer control.
Massive metal-bar grilles provide a beefy look and perfect woofer-cone protection.
