## Description

Product Description               The JBL GT-BassPro12 powered subwoofer pumps out lush, car-rocking bass through a design so cool you won’t want to hide it in your trunk. The patented Slipstream port design delivers deep bottom end while minimizing turbulence. Turbulence, or port noise at high volume, isn’t just annoying; it’s a signal that the port is no longer working and you’re getting less bass than you paid for. The Slipstream design is carefully optimised for the combination of woofer, amp and enclosure, and no other company has it. And with the included remote control for drive-time adjustments, the only time you’ll need to stop is for gas.                  From the Manufacturer               VIEW LARGER       JBL GT-BassPro12 Add amazing bass in very little space. The JBL® GT-BassPro12 powered subwoofer is the easy way to add high-output, low-distortion bass to a car audio system. Its Slipstream port design delivers deep, bottom-end bass while minimizing port noise. It also features improved motor-structure venting for thermal protection, a progressive spider to ensure superior mechanical reliability and an amplifier that delivers maximum power and flexibility. And with the system’s remote level control, which lets you adjust bass level while driving, the only time you’ll need to stop is for gas.

The port’s dual flares form an adverse pressure gradient that eliminates port noise at high output – noise that signals that the port is no longer able to pass enough air to operate effectively. The Slipstream port provides clean, distortion-free performance even at the highest output levels.

What’s more, the GT-BassPro12 will automatically turn itself off a few minutes after the signal stops.Oversized speaker-protection barsYour JBL® GT-BassPro12 powered subwoofer looks every bit as powerful as it sounds.
