JBL Grand Touring Series GTO1504D

The GTO1504D is a 15" Dual Voice Coil Subwoofer with Dual 4-Ohm Voice Coils. New proprietary frame, unique in-board motor structure and new cone design deliver a woofer that is a full inch shallower than equivalent sized models from competing brands. This approach allows for fit into more vehicles without a sacrifice in performance. Progressive spider provides better control at excursion limits and reduces woofer distortion. Hi-roll rubber surrounds provide exceptional cone edge suspension and long-throw linearity with the proper amount of control and stability at excursion limits. Vented pole-pieces provide additional cooling to the motor structure, resulting in an increase in the subwoofer's thermal power handling capability.
