The 11" (279mm) woofer cone is engineered to deliver fast and tight, deep bass with low distortion and unwanted second and third order anomalies.
The JBL subwoofer system’s built-in amplifier is optimized to work as a system with the woofer. Its Class D design runs cooler and draws less current from your vehicles electrical system making it the perfect concealed subwoofer solution.
Gain control adjusts the volume level right from the drivers seat. Phase switch changes the input phase to inverted or noninverted. (This can sometimes be helpful for troubleshooting.) Crossover frequency control adjusts the crossover frequency to any point between 50Hz and 150Hz. Bass EQ control provides 12dB of boost.
The JBL BassPro Hub has line level inputs and speaker inputs that allow you to connect it to any car audio system making it a great upgrade to your factory system or the bass foundation of the aftermarket system of your dreams.
JBL speakers have to undergo a testing process that would destroy lesser speakers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
This is JBL—the legendary speaker and sound company that has excited audio enthusiasts for over seventy years. There's nothing better than riding with JBL.
