DD Audio and European distributor AI Group have jointly developed a dedicated subwoofer for the European market.The Redline 600E series!

The result is a unique subwoofer with high sensitivity. Unlike other high sensitivity subwoofers, these elements also have a low FS, which allows you to produce REALLY BASS to the deepest Freuqenzkeller. 

The redesigned basket increases airflow and cools the voice coil more efficiently.It was the basketof the 700 series and the large lower suspensions were taken as a basis, which allow a large mechanical asulenkung. The motor is slightly larger than the normal 600 series and the voice coils are "Made In USA" - High Temp voice coils.

Triple voice coil ventilation, conductors braided into triple undersuspension, laminated undersuspension and extended pole pieces distinguish the new 600E series! The diaphragm is a blend of fiberglass and paper fiber and coated with a moisture-resistant coating. This creates a lightweight and strong membrane that can withstand any challenge!

The Redline 600e series is available with 2 × 2 or 2 × 4 Ohm voice coils. 10", 12" and 15" woofers are available.
