Two Punch Stage 2 DVC Woofers: The enclosure houses two
front-firing 12" dual 4-ohm voice coil woofers. The cones are constructed
of high modulus, closed conical polypropylene and have ABS/Acrylic dustcaps.
Polypropylene is lightweight and strong, giving the woofers high power handling
capabilities with low distortion.
High Density Poly-Foam Surround: A high density compressed
half-roll sealed poly-foam surround allows Punch woofers to produce a more linear
excursion resulting in more bass output.
Spider: A compliant linear spider made from tear and
fatigue resistant poly-cotton improves mechanical stability under high excursion,
maintaining consistent excursion characteristics.
Voice Coil: The woofers use high temperature voice coils with
a spun-laced Nomex insulating reinforcement collar which offers superior heat
dissipation over other commonly used materials.
Venturi-Effect Cooling System: The Venturi-Effect Cooling
system gradually reduces the air-flow exhaust path area and increases the air
speed across the key thermal masses of the woofer's motor parts which helps
reduce voice coil temperatures, improves thermal dissipation, and improves overall
reliability of the speaker.
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.
Basket: The Rockford Punch woofers feature sturdy 16-gauge
geometrical compound bend frames for added stability.
Solid MDF Construction: The enclosure is constructed of high
quality 5/8" MDF (medium-density fiberboard), which resists flexing and has
Vented Enclosure: The vented enclosure is aided by precision
construction through computer design. The enclosure consists of two front firing
12" Punch Stage 2 woofers with a centered, proprietary high-flow, low-noise
port. The speaker terminals are located on the left side of the box (when facing
the box). The box is covered in black carpet.
Tuned Port: The enclosure uses a front-firing proprietary
high-flow, low-noise port to help produce deep and loud bass efficiently.
Box Carpeting: The enclosure is finished with high-density
carpeting for superior durability. The carpet color is black.
Speaker Terminal: The subwoofer enclosure uses one pair of
high current, spring loaded binding posts to connect your amplifier to the speaker box
for maximum current transfer. The binding posts are located on the left side of
the box and will accept pin connectors, single or dual banana plugs, or bare
wire up to 12 gauge.
Wiring: The two dual 4-ohm voice coil Punch Stage 2 woofers
are wired in a combination of series and parallel inside the box to present
a 4-ohm load at the enclosure's speaker terminals.
Power Handling: Combined, the subwoofers can handle up to 500
watts RMS; 1000 watts peak power.
Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team. They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
