DB DRIVE WDX 12inch Subwoofer WDX12 G1.D4

PRODUCT DESCRIPTION- Our engineers at DB Drive have designed this subwoofer from the ground up to shake the ground up. The double stitched foam surround along with the die-cast aluminum vented basket allow for maximum excursion while the protective magnet cover gives the woofer a rugged yet stylish appearance. 3″ BASV High Temperature Voice coil Non-Pressed paper cone Double stitched foam surround Dual poly-cotton dampeners Die-cast aluminum vented basket Rubber gasket trim ring Large gauge compression terminals Protective magnet cover Physical Structure- Outside Diameter (A) 12.70″ (323.50mm) Cutout Diameter (B) 11.10″ (281.18mm) Mounting Depth (C) 6.85″ (173.80mm) General Specifications- Structure 12″ (30.48cm) Woofer Dynamic Power Handling 2000 Watts Nominal Power Handling 1000 Watts Impedance Dual 4Ω Voice Coil Parameters- Resonant Frequency (fs) 40.93Hz D.C.

Wiring the same woofer or multiple woofers in these three different wiring configurations will result in different impedance loads.Series: Is the method of wiring of alternate positive with negative terminals (string method) (Illustration below)Parallel:Is the method of wiring where you wire match 2 speaker terminals with positive to positive terminal and negative to negative. (Illustration below)Series/Parallel: This configuration is a combination of both series and parallel. We recommend series for the terminal and parallel for the leads to amp. (Illustration below).
