Shallow Mount Design: The
Rockford Fosgate Punch P3 Shallow Subwoofer is designed and engineered with a
much smaller motor assembly which reduces the overall depth of the woofer
allowing it to fit in shallower enclosures and tighter locations of your
Removable Magnet Cover: The
woofer's PVC textured magnet covered can be removed to allow for even shallower
installation applications. The cosmetic semi-flexible PVC magnet cover can be
removed when additional mounting clearance is required. With the magnet cover
installed, the woofer has the following dimensions:
- Magnet Diameter: 6.625"
- Depth as Top: 3.805"
- Depth as Bottom: 4.08"
Note: The dimensions listed in the
Specifications Table are without the magnet cover.
Dual 2-ohm Voice Coils: This
woofer features dual 2-ohm voice coils that offer flexibility in wiring. When
the voice coils are wired in parallel with each other, the woofer presents a 1-ohm mono load. When the voice coils are wired in series with each other, the
woofer presents a 4-ohm mono load. In addition, each coil may be connected to a
different amplifier channel and each channel will see a 2-ohm load.
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.
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.
Linear Spider: A compliant
linear spider made from tear and fatigue resistant poly-cotton improves
mechanical stability under high excursion, maintaining consistent excursion
characteristics. The spider rests in a vented spider cavity to reduce heat
Spherically Vented Motor: The spherically
vented spider and pole piece efficiently exhaust excessive heat away from the
woofer. This excessive heat that is dissipated through the spherically vented
motor reduces the operating temperature of the voice coil by over 50-degrees
Fahrenheit increasing the life of the woofer.
Basket: The Rockford Punch3 Shallow Woofer
features a sturdy die-cast aluminum frame which adds rigidity and eliminates
multiple acoustic resonances.
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 0.9375" and the ring diameter is 13.083".
Reverse Mounting: The Rockford Punch
Shallow 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.
Break-In Period: Due to the design of the
Rockford Fosgate P3 Shallow subwoofer, a 24 to 48 hour "break-in" period is
required to allow for maximum excursion and low frequency extension. The shallow
woofer suspension is intentionally designed to optimize once the internal
components are exercised under normal music listening conditions.
Recommended Sealed Box Volume: The sealed box sizes recommended by Rockford Fosgate range from
0.60 cu/ft to 1.20 cu/ft. Within this range, the ideal size recommended by
Rockford Fosgate is 1.0 cu/ft, so this is the enclosure recommended by
Recommended Vented Box
Volume: The vented box size recommended by Rockford Fosgate
is 1.25 cu/ft, so this is the enclosure recommended by Crutchfield. One 4"
diameter x 12" long port should be used with the 1.25 cu/ft enclosure.
