A progressive spider for better control

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

Exceptional venting, play long and loud

Woofer motor structures heat up during use, causing power compression that reduces music’s dynamic range, lowering output levels and robbing the sound of its realism. JBL® woofers use vented motor structures and polepieces to give you serious thermal power-handling capability.

Proprietary JBL® Slipstream port technology

The patented JBL® technology creates uniformity of airflow. No distortion. No port noise. Only precise, high-output, thunderous bass reaches your ears. The double-flared shape of the oversized port is precisely calculated for greater low-frequency extension and woofer protection.

Oversized, heavy-duty and reliable

You won’t find a tougher or more reliable woofer. It has dual-stacked oversized magnets, oversized protection bars – massive metal-bar grilles for a beefy look and woofer-cone protection. Proprietary terminals take heavy-duty speaker wires and are designed exclusively for JBL® products.

Outstanding audio output, low distortion

With 275 watts RMS and 1100 watts of peak power handling, the GTO1202BR changes the experience of listening to your favorite music in your car. And a progressive spider gives better control for lower distortion at excursion limits.

Optimized band-pass tuning

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