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 open the box,
verify contents, 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.
The cone uses a parabolic injection
molded polypropylene design. Polypropylene is lightweight
and strong, giving the woofer high power handling and low distortion.
Excursion Large Roll Surround:
A large edge roll surround allows Punch woofers to produce 20% more linear
excursion than standard surrounds, resulting in more bass output.
Anodized Aluminum Voice Coil
Former: Aluminum voice coil formers offer superior heat dissipation over
other commonly used materials. The hard-anodized finish on this 2" former increases
its strength. These two factors combine to improve the overall power handling characteristics
of the subwoofer.
Precision Stamped CRS Basket:
Reinforced cold roll steel basket legs dampen unwanted resonance for better bass
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.
Removable Magnet Cover: The
cosmetic magnet cover can be removed when additional mounting clearance is
required. With the magnet cover installed, the woofer has the following
- Magnet Diameter:
- Depth as top: 5.643"
The heavy-duty spring posts will accept pin connectors and bare wire up to 10
Concealing Ring: Once the
subwoofer is mounted, the concealing ring can be installed to hide the mounting
screws, giving the subwoofer a finished look. With the ring in place the
mounting height increases to 0.844".
