Key Features : Proprietary Slipstream port technology The double-flared shape of the oversized port is precisely calculated, efficiently eliminating port noise. Even at highSPL, airflow through the port will remain uniform, offering better low-frequency extension and woofer protection. Significantly improved power-handling capabilities The new GT5 enclosure generation handles 10 percent more power than previous CS and offers nearly 20 percentmore Xmaxfor higher SPL. 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 (GT5-1204BR and GT5-2402BR) come with massive metal-bar grilles for a beefy look and perfectwoofer-cone protection. Optimized band-pass tuning Unlike many inexpensive band-pass subwoofers, the GT5-1204BP is able to reproduce even the lowest bass frequenciesthanks to a carefully tuned enclosure. Proprietary terminals The large terminals are designed exclusively for JBL products and accept heavy-duty speaker wires.
