SoundQubed introduces our competition grade subwoofers with high power 4 inch voice coils. The HDC-4 subwoofers feature our largest and most powerful motor ever, coupled to a new frame and suspension system.
The 9.25 inch diameter multi-layer spider system with integrated lead wires provides well controlled excursions needed for advanced box tuning. The high gap flux powered by the triple stack, 10 inch diameter magnets add extra control while increasing sensitivity. Our laminated kevlar cones are used due to their excellent strength and durability.
The voice coils are high temperature flat wire aluminum on black anodized aluminum formers. 10 gauge Direct Connect wiring is used to lower resistance and make multiple wire connections as easy as possible.
