Description
The Power Tuned 818F sets standards 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, which masters even the strongest conversion of raw power into clean sound, the 818F stands for guaranteed longevity. The 800 series is already renowned for its high efficiency, but the 818F goes one step further with precision engineered cooling enhancements and groundbreaking design. The combination of a vented aluminum voice coil insert and a vented, finned aluminum heatsink ensures optimal heat dissipation. Other striking features are the higher excursion, 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 new type of rubber sleeve design on the motor.
