DB DRIVE WDX8G0.4 8″ SUBWOOFER (pair)

Description

The engineers at DB Drive have designed this subwoofer from the ground up to shake the ground up. The 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.

• 2″ High Temperature Voice coil
• Reinforced paper cone
• Dual poly-cotton dampeners
• Stamped Cast basket
• Rubber gasket trim ring
• Large gauge compression terminals
• Protective magnet cover

RECOMMENDED ENCLOSURES

4 OHM DVC WIRING CONFIGURATION

You can change the wiring configuration of your speakers (Series, Parallel and Series / Parallel) to match the impedance loads that maximizes the power output of you amplifier. 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 above)

Parallel: Is the method of wiring where you wire match 2 speaker terminals with positive to positive terminal and negative to negative. (Illustration above)

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 above).
