ENCLOSURES

For more than 60 years, JBL, Inc., has been 

delivering products embodying the technology 

developed in the professional arena – equipping 

leading recording studios and movie theaters, as 

well as live-music reinforcement in venues ranging 

from clubs to Woodstock. This expertise continues to 

drive products that provide the impact and excitement 

of a live performance. The JBL

®

 experience is for 

enthusiasts who won’t settle for anything less than 

“live” at home or on the go.

JBL GT5 enclosures deliver best-in-class performance 

for those looking to add bump in the trunk. Three 

loaded enclosures, the GT5-1202BP, GT5-1202BR and 

GT5-2402BR, are available in the GT5 lineup.

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.
