Beschreibung
The Power Tuned 818F sets the standard in the world of subwoofers. This 18" subwoofer is a premium product from DD Audio, the renowned manufacturer of audio equipment. With its advanced thermal cooling technology that masters even the strongest conversion of raw power into clean sound, the 818F stands for guaranteed longevity. The 800 series is already known for its high efficiency, but the 818F goes a step further with precision-engineered cooling improvements and groundbreaking design. The combination of a ventilated aluminum voice coil insert and a ventilated, finned aluminum heat sink ensures optimal heat dissipation. Other striking features include the higher excursion, which is made possible thanks to a stronger surround and a voice coil with a longer winding length, and the elegant design with engraved DD logos and a novel rubber boot design on the motor.
