DD Audio 1506 D4 ESP

Carbon Fiber Blend Cone (CFB) – The CFB composition employs a potent carbon fiber based cocktail to give you the highest strength to weight ratio of any pulp cone in the industry. Vario-density Extended Range Of Motion Surround (V-ROM) – Provides the ultimate in linear control at high excursion while still allowing for dynamic sounding bass reproduction. The control ribs are compressed to a lesser density than the main surround body to allow for a continuously variable control system. The harder you drive it the more control you get. Tuned Spider System (TSS) – Each suspension is tuned for specific performance traits, e.g. High Definition, Power Handling, X-Stiff Control. Super Frame (SFrame) – Maximizes spider diameter, cone diameter, suspension excursion, works as a secondary shorting ring and provides additional heat sinking for better heat flow from the coil.
