DD Audio 718f-D4 4500W 18" subwoofer

The new 700f series offers a selection of DD AUDIO's sturdy subwoofers with exceptional power durability and because of this they are suitable for even the most violent use!

HEAT TRANSFER
The ″F″ series subwoofers are designed to significantly improve heat transfer. The two-stage aluminum cooling element conducts the heat away from the moving parts together with the ″Free Flow Cooling System″ significantly better than the traditional engine design.

MORE XMAX
Compared to the old d-series, the top plate and voice coil of the elements have been increased, with which the model series offers an even bigger range of motion = MORE BASS!

With the increased range of motion, the suspensions of the elements have also been designed to meet the new requirements. A higher top suspension attached to the cone with double stitching. Multi-layer lower suspension guarantees the element better control, tighter bass and longer durability.


The new Redline 700f series is available with 2x2 or 2x4 ohm voice coils. The coil diameter is 3″. 10″, 12″, 15″ and 18″ elements are available.
