Description
The DD AUDIO 715g-D2 is a 15-inch, or 38 cm, subwoofer from the Power Tuned 700 G series. It handles 2000 W RMS and 4500 W peak. Its D2 dual voice coil consists of two 2 Ohm coils.
This generation combines a longer coil, a thickened top plate, a deeper gap, and a reinforced magnetic assembly. The 280 oz triple-stacked magnet motor is complemented by a dual-stage aluminum heat sink and free-flow cooling. Available at Sound Auto Concept, the 715g-D2 integrates into a custom enclosure project whose sizing must take into account the acoustic parameters and the subwoofer's footprint.
- 3-inch high-temperature voice coil.
- High, double-stitched surround.
- Glass-fiber-reinforced non-pressed cone.
- Double-layer centering surrounds.
- Recommended bass-reflex enclosure volume: 3.0 to 6.0 cubic feet.
