We believe in quality for the masses. The budget-minded audio enthusiast should be able to get quality car audio that fits into their price range. The REDLINE is our answer to that. These subs are hand-built in our offshore facility with the same high energy design philosophy as our HiDef and Power Tuned subwoofers making it possible to get the performance you demand, at the price you want.
The USA built, HiDef Tuned subwoofers feature a suspension that offers the perfect mix of control and efficiency, designed for systems where fidelity is the focus, and everyday listening will be done primarily inside the car. HiDef Tuned subs play fast, accurate and low. They work perfectly with the DD Box system, and due to their optimized suspension tuning, they also work great in acoustic suspension applications.
Our USA built, Power Tuned subwoofers are designed to push performance limits, yet still maintain a high level of control. Power Tuned subs feature additional mechanical and electrical damping to handle the rigors of crazy lows in daily high output applications. Power Tuned subs are meant to be heard not only in the car, but down the street... way down the street!
The Z series is the result of our ongoing study in the field of world subwoofer domination. The Z project represents the culmination of DD's ultimate engineering goal which is to push the limits of delivered energy by utilizing high-performance composite technologies. The Z series takes its place as the flagship of the DD sub line by having the highest motor strength, greatest voice coil cooling capability, most overbuilt design features, and last but not least True To The Source sound reproduction.
