Progressive Spider
Each GT5 enclosure features a progressive spider, which offers better control at the excursion limits than the linear spider commonly used by competitors. This progressive spider reduces distortion at high output levels.

Vented Polepieces
These provide additional cooling to the motor structure, resulting in an increase in the subwoofers’ thermal power-handling capability.

Proprietary Slipstream Port Technology
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.

Increased Reliability
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.

Dual-stacked Oversized Magnets
The increased magnetic flux results in higher efficiency and better woofer control.

Oversized Protection Bars
The ported models (GT5-1202BR and GT5-2402BR) come with massive metal-bar grilles for a beefy look and perfect woofer-cone protection.

Optimized Band-Pass Tuning
Unlike many inexpensive band-pass subwoofers, the GT5-1202BP is able to reproduce even the lowest bass frequencies thanks to a carefully tuned enclosure.

Proprietary Terminals
The large terminals are designed exclusively for JBL products and accept heavy-duty speaker wires.
