About the Rockford Fosgate P3D412

Dominic DeVito
Rockford Fosgate builds Punch Series Stage 3 subwoofers with advanced cooling technology and bulletproof cone materials so they'll give you years of trouble-free bass reinforcement.

Rockford Fosgate builds Punch Series Stage 3 subwoofers with advanced cooling technology and bulletproof cone materials so they'll give you years of trouble-free bass reinforcement.

Fiber cones deliver some of the truest low tones you'll ever hear, and they're reinforced with Kevlar® to add serious backbone to the rich sound quality. The extra-tall poly-ether-ester surround extends cone excursion, which translates into lows that are full and robust. A colossal 102-ounce magnet calls the shots, keeping cone movement under tight control for high accuracy.

The P3D412 12" subwoofer features a die-cast aluminum frame, motor cover, and trim ring, providing excellent heat transfer and reliable toughness. Rockford Fosgate's "Venturi-effect" design increases airflow through the sub's center area for maximum cooling. You get a sub that'll deliver long term performance and competition-worthy bass, even if you're only competing in the parking lot at the local shopping center.

Enclosure Compatibility


Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils that offer flexibility in wiring. When the voice coils are wired in parallel with each other, the woofer presents a 2-ohm mono load. When the voice coils are wired in series with each other, the woofer presents a 8-ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4-ohm load.

Woofer: The cone is constructed of Kevlar Fiber reinforced semi-pressed paper. The combination of these materials provide increased power handling capability, exceptional low bass response and long lasting durability.

Parabolic Cone Geometry Support System: By bonding a ABS/Acrylic parabolic dust cap of equivalent size to the cone body, a balanced geometrical structure is created. This system reduces piston flex and eliminates cone distortion.

High Excursion Tall Profile Surround: A tall profile, high excursion Poly-ether-ester surround allows for maximum linear travel without reducing overall piston size giving you the highest SPL levels possible.

High-Temp Voice Coils: The woofer uses a 2.5", 4-layer, high-temp, aluminum former or voice-coil with spun-lace Nomex reinforcement collars to provide excellent heat dissipation and SPL capabilities unlike many other plastic substitutes.

Dual Linear Spider with Vented Spider Cavity: A compliant dual linear spider improves mechanical stability under high excursion, maintaining consistent excursion characteristics. This eliminates the need for a "break-in period." The vented spider cavity helps improve the woofer's overall heat dissipation.

Double Stacked Magnet Motor Assembly: The stacked magnet assembly is used to create a powerful linear motor with increased excursion capability for superior bass output.

Optimized Motor Magnetics: The Punch3 woofer uses an extended pole piece and bumped backplate design to optimize its performance.

Venturi-Effect Cooling: The "Venturi-Effect" is created by gradually reducing the air-flow exhaust path area, which increases the air speed across the key thermal components of the speaker's motor parts maximizing cooling effectiveness. The benefit of the "Venturi-Effect" is the reduction of voice coil temperatures, substantially improving thermal dissipation, and improving overall reliability.

Basket: The Rockford Punch3 woofer features a sturdy die-cast aluminum frame which adds rigidity and eliminates multiple acoustic resonances.

Cast Aluminum Motor Cover: The woofer features a protective die-cast aluminum motor and magnet cover for improved heat dissipation.

Spring Post Assembly: The woofer features a custom insulated/isolated compression input terminal assembly with attached flexible, 16-gauge stitched tinsel lead wires that can withstand extreme duty cycles, fatigue and high current. The heavy-duty 10-gauge nickel spring posts will accept pin connectors and bare wire.

Decorative Ring: For an added decorative look the woofer comes supplied with a PVC decorative ring that mounts over the flange of the woofer. When using the PVC ring the woofer is first mounted into place with eight screws and then the ring is set on top the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. The decorative ring increases the top-mounting height of the woofer to 1.0625".

Reverse Mounting: The Rockford Punch woofer can be mounted in either direction. The aluminum decorative ring that is supplied with the woofer provides an easy and cosmetically finished look regardless of the mounting direction.

Enclosure Compatibility

Recommended Sealed Box Volume: The sealed box sizes recommended by Rockford Fosgate range from 0.75 cu/ft to 1.25 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 1.0 cu/ft, so this is the enclosure recommended by Crutchfield.

Recommended Vented Box Volume: The vented box size recommended by Rockford Fosgate is 1.79 cu/ft, so this is the enclosure recommended by Crutchfield. One 4" diameter x 10" long port should be used with the 1.79 cu/ft enclosure.
